Analyze Diet

Topic:Protein

Proteins are essential macromolecules that play diverse roles in the physiology and health of horses. They are composed of amino acids and are involved in various biological processes, including tissue growth, repair, and the synthesis of enzymes and hormones. Dietary proteins are a key component of equine nutrition, influencing muscle development, immune function, and overall performance. Horses require a balanced intake of essential amino acids, which must be obtained through their diet, as they cannot be synthesized endogenously. This page compiles peer-reviewed research studies and scholarly articles that explore the types, functions, and dietary requirements of proteins in horses, as well as their impact on equine health and performance.

Equilibria of organic phosphates with horse oxyhemoglobin.
Biochemistry    December 5, 1972   Volume 11, Issue 25 4660-4668 doi: 10.1021/bi00775a004
Hedlund B, Danielson C, Lovrien R.Organic phosphates, ATP, AMP, and 2,3-di-phosphoglycerate (DPG) were interacted with horse oxyhemo-globin. Binding parameters were obtained by means of dialysis equilibrium in buffers at 5°, and from calorimetry at 5 and 25°, all in the pH mom 6.5-7.3. The calorimetric results were evaluated assuming a single strong site, and assuming that the pH shifts which occur in the absence of added salt are due to electrostatic effects and not to changes in side-chain titration, upon mixing samples previously ad-justed to the same pH. There was obtained for ATP and 2,3- diphosphoglycerate. respectivel...

Production of antibody to homologous -fetoprotein in rabbits, rats and horses by immunization with human -fetoprotein.
Journal of immunology (Baltimore, Md. : 1950)    November 1, 1972   Volume 109, Issue 5 957-960 
Nishi S, Watabe H, Hirai H.The production of antibody to homologous alpha fetoprotein (AFP) in rabbits, rats, and horses by immunication with human AFP is reported. The antigens were administered subcutaneously 5 times at intervals of 7-10 days. Rabbits and dogs received 1 mg of human AFP/ml of the homologous pooled newborn serum with each injection while the rats received 1/2 of the dose. The horses received 5 mg/ml/injection. 2 weeks after the last injection, antisera were collected and immunologic assays were performed by the Ouchterlony method and the reversed version of the Mancini method. High titered antibodies w...
A DNA-binding protein in the serum of certain mammalian species.
Proceedings of the National Academy of Sciences of the United States of America    November 1, 1972   Volume 69, Issue 11 3327-3330 doi: 10.1073/pnas.69.11.3327
Thoburn R, Hurvitz AI, Kunkel HG.Various mammalian species contain an anionic serum protein that reacts specifically with native DNA. It is considerably less reactive with single-strand DNA and does not react with monodeoxyribonucleotides, homopolyribonucleotides, or duplexes of homopolyribonucleotides. Synthetic dA.dT was an effective inhibitor of the reaction with native DNA, while Micrococcus luteus DNA and dG.dC were not inhibitory. This protein was encountered in the course of studies on DNA antibodies. Although it reacted with red cells coated with DNA and gave agar precipitation bands, it was clearly distinct from DNA ...

Infection and immunity    October 1, 1972   Volume 6, Issue 4 610-615 doi: 10.1128/iai.6.4.610-615.1972
McGuire TC, Crawford TB.Immunoglobulin A (IgA) was demonstrated in equine serum and secretions. This immunoglobulin had a molecular weight extending from 150,000 to 700,000 and reacted with specific antihuman alpha-chain antiserum. Antigenic determinants specific for secretory IgA were demonstrated and found to be absent on serum IgA. Antigen binding activity was detected in IgA from tears. Purified IgA was antigenically distinct from equine IgG, IgM, IgG(T), and aggregating immunoglobulin. Quantitative studies demonstrated that IgA was the predominant immunoglobulin in tears and milk but not in colostrum. The electr...

Endocrinology    July 1, 1972   Volume 91, Issue 1 101-106 doi: 10.1210/endo-91-1-101
Gospodarowicz D.A highly purified preparation of PMSG has been obtained from fresh serum and from a commercial preparation. Carbohydrate and amino acid compositions have been determined. The carbohydrate content of PMSG is 46.7% and the molecule is rich in Sialic Acid (13.5%). The apparent molecular weight of PMSG has been determined by SDS polyacrylamide gel electrophoresis. A molecular weight of 53,000 has been found for the unreduced and unalkylated molecule. After reduction and alkylation, the molecular weight fell to 23,000. From these values it has been concluded that PMSG is an oligomeric molecule comp...
The autoxidation of horse hemoglobin: the effect of glutathione.
Biochimica et biophysica acta    June 26, 1972   Volume 273, Issue 1 30-39 doi: 10.1016/0304-4165(72)90188-2
Rifkind JM.The reduced glutathione in the erythrocyte was found to inhibit the autoxidation of purified horse hemoglobin. It was observed that much higher concentrations of oxidized glutathione also stabilize hemoglobin. The stabilization by oxidized glutathione most likely involves the formation of a mixed disulfide with the reactive β-93 sulfhydryl groups on the hemoglobin. A similar effect is also observed with N-ethyl- maleimide and HgCl2 which also react with the sulfhydryl groups. The apparent stabilization by reduced glutathione is partially due to the reduction of ferrihemoglobin formed by autox...

Characterization of an equine infectious anemia antigen extracted from infected horse spleen tissue.
Infection and immunity    November 1, 1971   Volume 4, Issue 5 528-531 doi: 10.1128/iai.4.5.528-531.1971
Norcross NL, Coggins L.The spleens of horses infected with equine infectious anemia contain an antigen that is useful for a diagnostic immunodiffusion test. This antigen was extracted from the spleen by homogenization of the tissue, centrifugation, and precipitation from the supernatant fluid at 50% saturation with (NH(4))(2)SO(4). The antigen was purified by subjecting it to two cycles of electrophoresis in a continuous free-flow electrophoresis cell and finally filtering through a column of Sephadex G-200 gel. The antigen was found to be a small protein with a molecular weight of 27,500 and sedimentation coefficie...
