Reid, M. E.; Bieri, J. G.; Plack, P. A.; Andrews, E. L. published the article 《Nutritional studies with the guinea pig. X. Determination of the linoleic acid requirement》. Keywords: CHROMATOGRAPHY; CITRATES; DERMATITIS; DIETARY FATS; ERYTHROCYTES; EXPERIMENTAL LAB STUDY; FATTY ACIDS, ESSENTIAL; GROWTH; GUINEA PIGS; KETOGLUTARIC ACID; LINOLEIC ACID; LIPID METABOLISM.They researched the compound: Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide( cas:129-18-0 ).Application In Synthesis of Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:129-18-0) here.
cf. CA 59, 9144d. Young male guinea pigs were reared for 6-14 weeks with purified diets containing varying levels of linoleic acid as corn oil, safflower oil, or methyl linoleate. A dietary level of about 1% of calories as linoleic acid was necessary for normal growth and skin condition. The fatty acid composition of erythrocytes from animals fed safflower oil was determined and the ratios of 5,8,11-eicosatrienoic-to-arachidonic (20:3/20:4) or oleic-to-linoleic ( 18:1/18:2) acids compared with the performance of the animals with respect to growth and dermal symptoms. One per cent of calories as linoleic acid gave a 20:3/20:4 ratio of 0.13 to 0.17, and a 18:1/18:2 ratio of 1.41 to 1.14. Homogenates of liver from linoleic acid-deficient guinea pigs had an elevated rate of oxidation of citrate and α-ketoglutarate.
