Abstract

Lipids of plants, animals and microorganisms frequently contain minor amounts of lipophylic derivatives of ethyleneglycol and related lower dihydric alcohols, which mostly have been overlooked in the part. Methods for the quantitative determination of diols in lipid hydrolyzates have been developed. In some particular cases, e. g. lipids of marine invertebrates, regenerating rat liver and young corn seeds comparatively high diol/glycerol ratios were found. Various methods for the structural investigation of diol lipids, including mass‐spectrometry and combined GLC‐mass‐spectrometry are described. The chemical structure of a number of diol lipids including simple neutral lipids, diol galactolipids and diol cholinephosphatides has been clarified, the existence of other types is probable. The biosynthetic pathways of the diol lipids seem to be similar to those of the glycerolipids.
