title: L-fucose metabolism in cystic fibrosis fibroblasts.
abstract: The capacity of skin fibroblasts from cystic fibrosis (CF) and non-CF individuals to incorporate exogenous L-fucose into various metabolic pools was compared. Incorporation into intracellular acid-soluble pools and extracellular glycopeptides was measured by a dual-label co-chromatographic technique, whereas total macromolecular incorporation was measured by a single-label procedure. Although CF and normal fibroblasts incorporate exogenous fucose into intracellular acid-soluble and high molecular weight compounds in a similar manner, CF cells appear to be characterized by an increased incorporation of label into low molecular weight extracellular glycopeptides.
