title: [Initial stages in the mechanism of protein glycosylation in human breast neoplasms].
abstract: It is discussed the rol of lipid intermediates in the biosynthesis of eucaryotic glycoproteins. Microsomal fraction isolated from malignant human breast tumors transferred Man and Glc from GDP-(14 C)-Man and UDP-(14 C)-Glc into lipid linked sugars and glycoproteins. The transference of Dol-PP-oligosaccharide to endogenous acceptor proteins was catalyzed for the same microsomal fraction.
