Critical Review: Essential Fatty Acids on Shrimp Feeding
Four types of poly unsaturated fatty acids (PUFA) are essential for all shrimp species, linoleic (LOA, 18:2n-6), alfa-linolenic (ALA, 18:3n-3), eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3) acids. Moreover, the arachidonic acid (ARA, 20:4n-6), even when present, seems to be, in crustaceans, not so important or yet dispensable. It is relevant knowing that cholesterol as much...
متن کاملBiosynthesis of cholesterol and fatty acids in tumor-bearing animals.
Much information has been published on the relationship of lipides to tumorigenesis (17), but most of the work has been concerned primarily with the more quantitative aspects of lipides in tumors and in the tissues of tumor-bearing ani mals. Investigations on the course of lipide bio genesis have been few. In a continuation of earlier work in this laboratory with normal animals (23), it seemed ...
متن کاملThe biosynthesis of radioactive fatty acids and cholesterol.
The biological synthesis of long chain fatty acids from acetate by slices of rat liver tissue was demonstrated by Bloch, Borek, and Rittenberg (1) in 1946, and has been repeated by several investigators (2, 3). The effect of insulin on this incorporation was studied by Bloch and Kramer (2), who reported that, whereas insulin inhibited the incorporation of labeled acetate into fatty acids, the c...
متن کاملEffects of dietary cholesterol and fatty acids on plasma lipoproteins.
The effects of dietary cholesterol and fatty acids on low density and high density lipoproteins (LDL and HDL) were studied in 20 young men. After 2-3 wk of evaluations on ad lib. diets, basal diets, which consisted of 15% protein, 45% carbohydrates, 40% fat, and 300 mg/day of cholesterol, were given for 4-5 wk (Basal). The ratio of dietary polyunsaturated to saturated fatty acids (P/S) for diff...
متن کاملThe synthesis of radioactive cholesterol and fatty acids in vitro.
It has been established that rat liver slices are able to convert acetate (l), acetone (2), pyruvate (3, 4), butyrate, hexanoate, and octanoate (4) to cholesterol and long chain fatty acids. Zabin and Bloch (5) and Price and Rittenberg (6) administered 1 ,3-C14-acetone to rats and demonstrated that it is converted to fatty acids and cholesterol. The former investigators (5) also reported that m...
