Topic:Cholesterol
Cholesterol in horses is a lipid molecule found in the blood that plays a role in various physiological processes, including cell membrane structure and hormone synthesis. It is obtained from dietary sources and synthesized in the liver. Cholesterol levels in horses can be indicative of metabolic health and are influenced by factors such as diet, age, and activity level. Measuring cholesterol concentrations can assist in assessing the nutritional status and detecting metabolic disorders in equines. This page aggregates peer-reviewed research studies and scholarly articles that explore the metabolism, regulation, and clinical implications of cholesterol in equine health.
Formation of estrogens by the pregnant mare. II. Metabolism of 14C-acetate and 3H-cholesterol injected into the fetal circulation. A mixture of 14C-sodium acetate and 3H-cholesterol was injected into the umbilical circulation of a pregnant mare in the 3OOth day of gestation. The abdomen was closed and urine was collected for 3.5 days. The mare delivered a normal live foal 23 days later. Steroid conjugates present in the maternal urine were hydrolyzed and separated into neutral and phenolic fractions. From the phenolic “sulfate” fraction estrone, 17α-estradiol, equilin, equilenin, and 17α-dihydroequilenin were isolated. Only estrone and 17α-estradiol contained both 3H and 14C, while the ring-B unsaturated estrogens ...
Composition of neutral lipids from erythrocytes of common mammals. The neutral lipids of the erythrocytes were investigated in several common mammals: cow, dog, goat, horse, pig, rabbit, rat, and sheep. Cholesterol content was determined by gas-liquid, thin-layer, and column chromatography, the last in conjunction with the IR spectrophotometry. The three methods yielded similar results. In every species investigated, cholesterol was the major neutral lipid; cholesteryl esters, triglycerides, and free fatty acids were detected only in trace amounts. It is concluded that these substances may have been contaminants from plasma lipoproteins or leukocytes rather t...
Serum lipid, lipoprotein and vascular tissue studies in cholesterol-fed horse. No abstract available
Levels of some chemical constituents in normal horse sera. THE chemical analyses reported in this paper arc the result of an investigation on the sera of thirty normal horses from a heavy draught horse stable in Glasgow. Determinations have been made of scrum proteins (albumin and total globulin), alkaline phosphatase, bilirubin, calcium, magnesium, inorganic phosphate and urea. Estimations of some of these constituents have already been carried out by a number of workers, but in the majority of cases the investigation has been confined to one or two constituents relevant to the problem being studied, and many of the data available are a by-product of...
