SUMMARYGas liquid chromatography was used to investigate the influence of several T, S and unclassified cytoplasms on the fatty acid composition of oil from A632 and CrS4HLA maize seeds. The fatty acid compositions of the A632 and CrS4HLA seeds differed markedly from each other with respect to oleic and linoleic acids but were stable within each seed line with respect to all sixteen of the cytoplasms tested.

Fatty Acid Compositions

The fatty acid compositions of the oils of several spore forms of seven species of Gymnosporangium were determined by gas–liquid chromatography. No simple relationships were found between the host plants and the compositions of the spore oils. cis-9, 10-Epoxyoctadecanoic acid was found in the teliospore oil of five of the species. The oil of basidiospores closely resembled that of teliospores but there was considerable variation in the oil of aeciospores. In one species the aeciospore and teliospore oils were very similar to each other, in another species there was partial resemblance, and in a third species they were different. The fats from four "axenic" cultures of Gymnosporangium juniperi-virginianae Schw. were analyzed, and were quite different from those of any of the rust species but resembled those frequently obtained from the vegetative stages of many species of fungi.

Oil extracted from four different varieties of corn (Zea mays) were evaluated in terms of lipid, glyceride and fatty acid compositions. The total lipid extracts were fractionated into lipid classes by silicic acid chromatography. The neutral lipids were found to be 96.80 - 97.50 %; glycolipid 1.50-1.66 %; phospholipid 0.80-0.95 % respectively. The fatty acid composition of triglyceride (TG) fraction was analysed by gas liquid chromatography (GLC). The percentage composition of fatty acid were found to be linoleic acid 35.62 to 49.5 %, palmitic acid 8.7 to 9.9 %, stearic acid 1.9 to 2.3 %, myristic acid 0.9 to 1.6 % and linolenic acid 0 to 2.2 %.

Fatty Acid Compositions

The lipids of the subcellular fractions of ovine heart homogenate have been separated by chromatography on silicic acid into cholesteryl ester, glyceride and free fatty acid, and phospholipid fractions. Gas–liquid chromatography was used to determine the fatty acid compositions of these fractions.In all the subcellular organelles, phospholipid was the major lipid class, but in the cell sap fraction, glycerides predominated.By means of this lipid fractionation, and the presence in this tissue of two unusual major components, it has been possible to demonstrate a differential distribution of fatty acids between the separate subcellular fractions. The significance of this finding has been discussed in relation to the functions of lipids, the processes of fatty acid desaturation in the cell, and membrane biochemistry.The phospholipids of ovine mitochondria have been shown to be markedly saturated by comparison with the properties of this fraction in other mammals, and the implications of this lack of polyunsaturated components are considered in the Discussion.
