title: The cell-envelope glycolipids of baker's yeast.
abstract: Sphingolipids were found to dominate in the glycolipids from the cell envelope of baker's yeast. A relatively large quantity of ceramides was detected. Among the several complex phosphosphingolipids described, ceramide-(P-inositol)(2)-mannose was the main component. About 55% of long-chain bases in sphingolipids consisted of C(18)-phytosphingosine (4D-hydroxysphinganine). Other bases, found in decreasing concentrations, were C(20)-phytosphingosine, C(20)-dehydrophytosphingosine, C(18)-dihydrosphingosine (sphinganine) and C(19)-dihydrosphingosine. The presence of sterol glycosides, sulpholipids, cerebrosides and acylglucoses was demonstrated.
