Glyceride Compositions of Natural Fats

Regularities in the glyceride structure of vegetable seed-fats.

The fatty acid and glyceride structures of Indian buffalo milk and depot fats, and some characteristics of eastern animal fats.

This work describes the fatty acid and glyceride structures of Indian buffalo milk and depot fats. Only three other an4lyses of buffalo milk fat exist in the literature (Bhattacharya & Hilditch, 1931; Heiduschka & Cicekdagi, 1940), in only one of which was an examination made of the glyceride configuration, while no analysis of buffalo depot fat has so far been reported. The work below was ther...

A Radioautographic Study of Glyceride Synthesis in Vivo during Intestinal Absorption of Fats and Labeled Glucose

Radioautography was used to detect the synthesis of labeled glycerides in intestinal absorptive cells following injections of fatty chyme and glucose-6-H(3) into ligated segments of upper jejunum of fasting rats. Absorption intervals ranged from 2 to 20 min. Labeling is evident throughout the cells in as short a time as 2 min. Most grains are present over droplets of absorbed fat beginning with...

Natural closures, natural compositions and natural sums of monotone operators

We introduce new methods for defining generalized sums of monotone operators and generalized compositions of monotone operators with linear maps. Under asymptotic conditions we show these operations coincide with the usual ones. When the monotone operators are subdifferentials of convex functions, a similar conclusion holds. We compare these generalized operations with previous constructions by...

Activity of microbial lipases on natural fats and synthetic triglycerides.

The positional and fatty acid specificities of lipases from several different microorganisms have been examined by gas-liquid chromatographic analysis of the free fatty acids following action on mixed triglycerides of known composition. Three types of lipases were found. Lipases of the first type, obtained from several microorganisms, attacked primarily the 1-position of the triglyceride in a m...
