1. An active fraction which stimulates the exchange of phospholipids between microsomal fractions and mitochondria was isolated by gel filtration from potato tuber homogenates. 2. This fraction is probably a protein since the stimulatory factor is nondialyzable and temperature-sensitive. The
A method for rapid isolation of glyco- and phospholipids from potato leaves by a two-fold separation in a thin layer of silica gel is described. Using gas-liquid chromatography, the fatty acid compositions of monogalactosyldiglyceride, digalactosyldiglyceride, sulfolipid, phosphatidyl choline,
Four Canadian varieties of potatoes were examined for their lipid composition. Lipids, extracted with chloroformmethanol, were shown by TLC and column chromatography to consist of 16.5% neutral lipids, 45.5% phospholipids and 38.1% glycolipids. Among the phospholipids and glycolipids, phosphatidyl
