Lipid Intermediates in the Synthesis of the Inner Core of Yeast Mannan

The synthesis by yeast microsomes of compounds that are probably dolichol‐pyrophosphate derivatives containing N,N′‐diacetylchitobiose and several mannose residues is described. However, the presence of monosaccharide residues other than N‐acetylglucosamine and mannose has not been ruled out. The am...
