Glycosyl

(biochemistry) A univalent functional group derived from the cyclic form of glycose by removal of the hemiacetal hydroxyl group.

A univalent radical resulting from detachment of a hydroxyl group from the hemiacetal of a cyclic glucose.

A radical derived from a carbohydrate.

• g. transferases — enzymes catalyzing the transfer of a monosaccharide unit from a nucleotide-linked sugar to the non-reducing end of an oligosaccharide chain, or to an appropriate functional group on a protein.

A glycosyl group is a univalent free radical structure obtained by removing the hemiacetal hydroxyl group from the cyclic form of a monosaccharide and, by extension, of a lower oligosaccharide.
