TLDR
A rapid method for the stereospecific analysis of triglycerides based on enzymatic hydrolysis on thin layer plates was applied to a number of GlyCine max, Glycine soya, Avena sativa and Avena sterilis strains and large deviations from the common triglyceride pattern were not found.Abstract:
A rapid method for the stereospecific analysis of triglycerides based on enzymatic hydrolysis on thin layer plates was applied to a number ofGlycine max, Glycine soya, Avena sativa andAvena sterilis strains. The percentage of each fatty acid on thesn-1,sn-2- andsn-3-positions was linearly related to the total percentage of the fatty acid in the triglyceride. Large deviations from the common triglyceride pattern were not found.read more

Organization of Rapid Analysis of Lipids in Many Individual Plants
TL;DR: Modern plant breeding is largely empirical and produces large numbers of plants whose oilseed composition must be evaluated, and plant breeders turn to those skilled in oilseed analysis to identify those with interesting compositions.

Biomodification of fats and oils: Trials withCandida lipolytica
TL;DR: The greatest potential for biomodification by fermentation with C. lipolytica seems to be in altering glyceride structure, and the fatty acid composition of the yeast oil was quite similar to that of the substrate oil under optimum conditions of deposition.

Phospholipid fatty acid composition and stereospecific distribution of soybeans with a wide range of fatty acid composition
TL;DR: Stereospecific analysis showed that saturated fatty acids were primarily located at the sn-1 position of all PL, and changes of the saturates in PL were largely reflected on this position.

Improving the fatty acid composition of soybean oil
Earl G. Hammond,Walter R. Fehr +1 more
TL;DR: Recent work using hybrid crosses and induced mutations to improve the composition of soybean oil by breeding the beans for low linolenic acid in the oil is reported.

Evaluation of lipase selectivity for hydrolysis
TL;DR: The recovery of oleic acid from several lipase-catalyzed hydrolyses of 1(3)-palmitoyl-2-oleoyl -3(1)-stearoyl glycerol (POS) reported here, therefore, must be regarded as due to the presence of the lipases themselves.

Stereospecific analysis of triglycerides: an alternative method
TL;DR: A new method for the stereospecific analysis of triglycerides is demonstrated on a corn oil which had been analyzed by an earlier method, and has the advantage over the one reported previously of yielding direct analyses of the fatty acids in each of the three positions.

A micromethod for the stereospecific determination of triglyceride structure
TL;DR: Triglyceride lipase and diglyceride kinase can be used in a sensitive stereospecific analysis of the separate fatty acid compositions at the 1, 2 and 3 positions of a triglyceride.

Genetics, characteristics, and utilization of oil in caryopses of oat species
K. J. Frey,E. G. Hammond +1 more
TL;DR: Oats contained a lipase that made extraction of oil with low acid values difficult and was most active in oat doughs containing 25–50% moisture, and there was at least a 20-fold variation in lipase activity in Oat cultivars and collections.
