title: The incorporation of [14C]glucosamine into dolichol diphosphate N-acetyl[14C] glucosamine by unbroken liver cells in culture.
abstract: Incubation of whole Chang liver cells with D-[1-14C]glucosamine results in incorporation of radioactivity into both proteins and lipids. A minor (approximately 3%) amount of the labelled lipid has the chromatographic, solubility and chemical properties of dolichol diphosphate N-acetylglucosamine. A similar compound is formed when membrane preparations of the cells are incubated with UDP-N-acetyl[14C]glucosamine. The same membrane fractions catalyse the transfer of [14C]-mannose from GDP-[14C]mannose to dolichol phosphate.
