Abstract
Summary: Evidence has been presented that the proportions of the glyceride types and isomeric forms in some fats in which C16−C18 chains are greatly in excess can be determined by calculations based on a) the percentage of saturated acyl groups in the whole fat, b) the percentage of saturated groups in the 2‐monoglycerides which can be derived from the fats by hydrolysis, c) the assumption that all the saturated and unsaturated acyl groups (S and U) present in each of the three positions in the molecules are dispersed therein at random, and d) the assumption that the proportions of S and U in the 1‐positions are identical with those in the 3‐positions. The method may apply to all predominantly C16−C18 fats and to other fats as well.
