OLIGOSACCHARIDE
Pronunciation (US): | (GB): |
I. (noun)
Sense 1
Meaning:
Any of the carbohydrates that yield only a few monosaccharide molecules on complete hydrolysis
Classified under:
Hypernyms ("oligosaccharide" is a kind of...):
carbohydrate; saccharide; sugar (an essential structural component of living cells and source of energy for animals; includes simple sugars with small molecules as well as macromolecular substances; are classified according to the number of monosaccharide groups they contain)
Hyponyms (each of the following is a kind of "oligosaccharide"):
disaccharide (any of a variety of carbohydrates that yield two monosaccharide molecules on complete hydrolysis)
tetrasaccharide (any of a variety of carbohydrates that yield four monosaccharide molecules on complete hydrolysis)
trisaccharide (any of a variety of carbohydrates that yield three monosaccharide molecules on complete hydrolysis)
Context examples:

(Phytohemagglutinin, NCI Thesaurus)
A glycosylation site is an amino acid residue within a peptide that accepts oligosaccharide via amide linkage, specifically through amide nitrogen of asparagine via N-acetylglucosamine, as one of the post-translational modifications.
(N-Glycosylation Site, NCI Thesaurus)
