“Excess vitamin A stimulated the incorporation of mannose into rat liver mannosylretinylphosphate (MRP), dolichylmannosylphosphate (DMP), and into glycoproteins by over 200% during a 20-min labeling period.”
“The results suggest that excess vitamin A stimulates the incorporation of mannose into glycoproteins by enhancing the synthesis of lipid intermediates involved in specific mannosyl transfer reactions.”
