title: Studies on the diversity of inositol-containing yeast phospholipids: incorporation of 2-deoxyglucose into lipid.
abstract: Seven inositol-containing phospholipids in Saccharomyces cerevisiae can be resolved by two-dimensional chromatography on silicic acid-impregnated paper. Four of these lipids are stable to mild alkaline methanolysis; one of these has already been characterized as a mannosyl di(inositolphosphoryl) ceramide. Addition of labeled 2-deoxy-d-glucose to a growing culture results in label appearing in five lipids, some of which are alkali-stable and have the same R(F) values as the alkali-stable inositol-containing phospholipids. These lipids are labeled rapidly. The deoxyglucose is incorporated intact, probably in a glycosidic link, since the deoxyglucose is released by mild acid treatment.
