The study of biochemistry in horses encompasses the chemical processes and substances that occur within equine organisms. This field investigates the molecular interactions and pathways that are fundamental to horse physiology, including metabolism, enzyme activity, and genetic expression. Key areas of interest include the examination of metabolic disorders, nutrient absorption, and the biochemical basis of muscle function and energy production. Researchers utilize biochemical analysis to understand health and disease mechanisms in horses, contributing to the development of diagnostic tools and therapeutic strategies. This page gathers peer-reviewed studies and scholarly articles that explore various biochemical processes and their implications for equine health and performance.
Some aspects of the desoxyribonuclease activities of animal tissues. It has been found that many animal tissues contain "acid" desoxyribonucleases with pH optima near 5.2. A chemical method for the determination of this activity is described. The pancreatic desoxyribonuclease crystallized by Kunitz and shown to have a neutral pH optimum occurs in the pancreas together with the "acid" enzyme, but only the "neutral" enzyme occurs in the pancreatic juice. The ratio of "neutral" to "acid" DNAase activities in the pancreas is greater than 200, but in all other tissues examined there is no appreciable concentration of the neutral enzyme. It is concluded that neutral ...
The demonstration of a non-estrogenic uterine stimulating and estrogen augmenting substance in pregnant mares’ urine. THE occurrence of substances, in the extracts of human urine and of testes, that are capable of augmenting the effects of estrogens or androgens has been postulated and demonstrated by various workers. Freud and co-workers (1933, 1935) obtained factors from extracts of testes and human urine that augmented the effects of androgens, although possessing no androgenic activity themselves. Emmens (1938) described the presence of substances in the phenolic fraction of normal human female urine which in themselves were non-estrogenic, but when given orally, increased the potency of estriol injected ...
The action of acid phosphate on the anion permeability of horse erythrocytes. In 1941, Keilin & Mann described an optical method of studying the penetration of erythrocytes by bicarbonate ions and the intracellular activity of carbonic anhydrase. This method consists of converting the haemoglobin inside the cell to methaemoglobin and observing the transformation of the methaemoglobin from the acid to the alkaline form by the entering bicarbonate ions. During this work they noticed that this transformation did not occur if the methaemoglobin cells had been washed in acid phosphate and interpreted this as an effect on the permeability of the cells. Similar observations by...
Distribution of the fatty acids in the liver lipoids of the horse. IN the liver lipids of animals which have so far been examined it has been found1 that the phospholipids, as compared with the glycerides, contain less hexadecenoic acid but more stearic and highly unsaturated C20 and C22 acids, the latter being derived from dietary linoleic and linolenic acids2. Phospholipids, moreover, are generally regarded as selecting the more highly unsaturated acids from the diet3.
The esterases of horse blood; the specificity of horse plasma cholinesterase and ali-esterase. The research article delves into the exploration of the specificity of esterases in horse blood, particularly plasma cholinesterase and the ali-esterase, drawing a clear distinction between the two, which had […]
