Description
Technical field
The present invention relates to a kind of complex compounds, especially sucrose copper complex and preparation method thereof, and disclose its purposes.
Background technique
Nineteen twenty-eight, the Hart of University of Wisconsin (WisconsinUniversity) after research feeding milk by occurring
The rat of anaemia, after proposing that addition copper and iron are necessary this viewpoint to the formation of ferroheme, copper is important in nutrition
Property just gains recognition.Hereafter research confirms that the hematopoiesis of copper and body has close relationship in succession.Animal goes out after lacking copper
Existing low pigment small cell anemia.Further study showed that copper is joined by influencing absorption, release, transport and the utilization of iron
With hematopoiesis.Suitable copper can promote the absorption of enteron aisle iron, promote intracorporal iron to enter marrow by storing place, make nothing
Machine iron becomes Organic Iron, the exchange between ferric iron and ferrous iron is completed, to be conducive to the transport and utilization of iron.Copper can also add
The synthesis of fast hemoglobin and porphyrin promotes erythroneocytosis mature and discharges.
Animal is the reduction of blood copper first after lacking copper, and the decline of liver copper deposit then develops to serum and red blood cell copper content subtracts
It is few, it is formed Hypocupremia (hypocupperemia).The absorption of animal with Hypocupremia, enteron aisle iron is reduced, liver,kidney,spleen
And serum levels of iron reduces, serum be averaged the reduction of iron saturation degree, the raising of total iron integration capability, and the iron stored in tissue cannot be mobilized.
Thus iron be gathered in it is various cannot discharge and transport into the cell, marrow is suppressed using the process of iron, the synthesis of hemoglobin
It reduces, the maturity period of erythroneocytosis extends, and the lost of life of mature erythrocyte, the iron plasma clearance time extends.Thus it leads
It causes red cell volume to reduce, low pigment small cell anemia occurs.At this time, take orally or inject iron and vitamin B12Without effectiveness,
And after giving a small amount of mantoquitas, the metabolic disorder of iron, which can get, to be significantly improved.If being injected intravenously mantoquita albumen, the disappearance of above-mentioned symptom
It is more rapid.Accordingly, influence of the copper to body iron metabolism and hematopoietic function is mainly carried out by ceruloplasmin.
Copper is the composition of many enzymes in body.Such as cromoci, tyrosinase, ascorbic acid oxidase, uricase
Contain copper with galactase.These enzymes are transformed into O in superoxide anion free radical2And H2O2During play it is important
Catalytic action.In addition copper is also the important composition of superoxide dismutase and monoamine oxidase system.These enzymes are primarily present
In intracorporal elastic fibrous tissue and connective tissue, lysine residue is changed into aldehyde radical in catalyzed elastomeric protein peptide chain.And by with
The similar aldehyde radical or amino of intermolecular another peptide chain carry out aldol condensation or aldimine condensation, and then are formed between elastic protein fiber
Covalently cross-linked structure.Elastomer is set to become insoluble state, to maintain the toughness and elasticity of tissue.After lacking copper, cell color
The activity reduction of plain oxidizing ferment, catalase, phosphatide enzyme, succinate dehydrogenase, fatty Phosphorylation events delay, cell
Respiratory metabolism and fission process cannot normally carry out.
Since lysyl oxidase activity reduces after lacking copper, covalently cross-linked structure forms barrier in elastin laminin and collagenous fibres
Hinder, collagen and elastin laminin are mature slowly, and tissue elastase content is reduced, and the brittleness of the tissues such as blood vessel, bone is caused to increase
Add, angiorrhoxis, the osteodystrophies symptom such as skeleton deformity, fracture occurs.Copper is as superoxide dismutase and cytochromes
The prothetic group of oxidizing ferment can promote the synthesis of cephalin and participate in Energy Metabolism of Brain Tissue.Scarce copper can cause cephalin dyssynthesis,
There is incoordination, hindlimb paralysis.In addition, myocardium inner cell chromo-oxidase is more sensitive to scarce copper, scarce copper can cause cardiac muscle
Denaturation and heart failure.
Copper grows animal hair and pigmented influence has been confirmed by many scholars.The physical characteristic of wool, including
Crimpiness all relies on the presence of disulfide group inside, and disulfide group not only influences the arrangement of keratin long-chain in wool fiber and determines
To, while also being combined by the intersection of disulfide group or in conjunction with keratin, forming distinctive curling in wool fiber.And copper is herein
Be chiefly to facilitate in the process disulfide group formation and disulfide group intersection combine or and keratin combination.Lack the sheep of copper individual
Hair lacks crimpiness, even straight line wool or " silk thread hair ", greatly affected the quality of wool.In default of curling
Wool elasticity is abnormal, and tensile strength reduces.In terms of the pigmentation of hair, copper can promote the formation of tyrosinase and increase
Its strong activity.And tyrosinase is the premise that tyrosine is changed into melanin --- the catalyst of DOPA.And by DOPA
The participation of copper is also required for during being changed into melanin again.Therefore, some research discoveries, in dark hair copper content compared with
It is high.Copper can make the coat of animal fade after lacking, especially circumocular hair most fugitive color.Pig is removed in the animal of coloured coat
Outside, performance of the coat colour fading than anemia comes fastly after lacking copper.It is believed that the achroa of hair, which can be used for animal, lacks copper
Early diagnosis.In addition, it is reported that, the curling of wool, which disappears, also can be used as its early diagnosis for lacking copper.
Copper is the prothetic group of brain superoxide dismutase, can promote the synthesis of cephalin, and is the auxiliary of cytochrome oxidase
Base has the function of transmitting generation of the electronics to guarantee ATP.Scarce copper will cause shrinking of brain tissues, and regression occurs for grey matter and white matter
Venereal disease becomes, and neuron is reduced, drowsiness, reduces to the susceptibility of body stimulation.Copper excessively can also cause brain tissue and nerve cell
Lesion occurs, causes incoordination and spirit variation.Copper has an effect on the function of organism endocrine body of gland, to adjust body extensively
Various activities, copper can promote hypophysis growth hormone releasing (GH), thyrotropic hormone (TSH), metakentrin (LH) and
Corticotropin (ACTH), can also influence the synthesis of adrenocorticotro and catecholamine.Otherwise it is above-mentioned to swash
The variation of element also will affect the metabolism of copper in body.In addition, copper in conjunction with some drugs after can enhance its effect, in swine rearing
In the process, with high-copper cooperation antibiotic growth-promoting effect become apparent than individually with copper or antibiotic, mechanism need into
One step research.
Many researchs in recent years prove that there is also extremely close relationships between copper and the reproduction of animal.Someone
Think, breeding activity is than maintaining normal vital movement to need more copper (Van Niekrk, 1988).It, can when amount of copper is normal
To maintain the During Pregnancy of animal to be normally carried out, after lacking copper, embryonic death often occurs and is absorbed, breeding potential is caused to decline,
Lacking the ox fertility that copper weed is herded on the ground reduces, while post-estrus occurs and prolonging or inhibit, even if being pregnant sometimes, it is also possible to go out
Now miscarry.After raising seriously to lack feed 20 weeks of copper (0.7-0.9 μ g/g), egg production reduces hen, copper in blood plasma, liver and egg
Lower than normally, the hatching rate of hatching egg declines rapidly level, and the embryo of this hatching egg shows anaemia, and hypoevolutism is being incubated for 72-96h
Bleeding rate is very high afterwards.By inference, all these performances, it may be that due in embryonic development early stage, the generation and connective of red blood cell
The reason that tissue is obstructed.On the other hand, copper is also apparent from the inhibiting effect of reproduction, and mechanism of action mainly has: 1.
Low concentration copper ion has certain toxic action to sperm；2. copper oxide can reduce the viscosity of cervical discharge, and energy
Cervical mucus is dissolved, to interfere the movement of sperm and the implantation of zygote；3. secretory endometrium cell neutral and alkali phosphoric acid
The activity of enzyme, carbonic anhydrase and β hyaluronidase is inhibited by copper ion.But copper ion, which has, improves proliferative phase of endometrium cell
The effect of middle acid phosphatase, to influence reproductive process；4. a part of copper ion that endometrium absorbs can interfere or a word used in person's names
The content and metabolism of zinc, manganese, molybdenum, iron etc. in anti-endo cell, and research has obtained sufficiently importance of the zinc to fertility in many ways
Certainly.
Copper is microelement necessary to animal, they play an important role in animal body, and lacking microelement can be with
Cause being greatly lowered for growth of animal and production performance, directly influences the culture efficiency of raiser.Conjunction of the copper in ferroheme
It is many kinds of enzymes such as Ferroxidase, lysyloxidase, peroxide at playing an important role in the maturation with red blood cell
The constituent of mutase and cytochrome C oxidase etc., in vivo pigment deposition, neurotransmission and carbohydrate and protein,
It plays an important role in terms of amino acid metabolism, while also participating in composition, the calmness of coat pigment and the brain cell and spinal cord of bone
Matter etc..
The content and potency of contained microelement are needed there are larger difference through feed addictive form in feedstuff
It is added.It is mostly in use using inorganic microelements, inorganic microelements such as copper sulphate in production and practice at present
Have the following deficiencies: that bioavailability is low, animal is only capable of not being utilized using the inorganic microelement below of additive amount 10%
Part is then excluded the burden for not only causing to waste but also increase animal body and environment in vitro；In addition the microelement gold of ionic state
Belonging to ion is influenced in enteron aisle by phytic acid, oxalic acid and cellulose, its absorptivity is further decreased；Antagonism between element simultaneously
Effect also influences biological value, and the redox reaction between metal ion can damage vitamin, to make nutriment
It is lost, reduces its absorption rate.
With the development of feed industry and the progress of aquaculture, the feed addictives such as microelement, amino acid, which have become, matches
Close the indispensable raw material of feed.The micro of various dose is added according to different animals nutritional need in people in mixed feed
