heparan sulfate

 [hep´ah-ran]
a sulfated mucopolysaccharide structurally related to heparin, which occurs normally in the liver, aorta, and lung; it is an accumulation product in several mucopolysaccharidoses.

hep·a·ran sul·fate

(hep'ă-ran sŭl'fāt),
A heteropolysaccharide that has the same repeating disaccharide as heparin but with fewer sulfates and more acetyl groups; accumulates in people with certain types of mucopolysaccharidosis.
Synonym(s): heparitin sulfate

heparan sulfate

/hep·a·ran sul·fate/ (hep´ah-ran) a glycosaminoglycan occurring in the cell membrane of most cells, consisting of a repeating disaccharide unit of glucosamine and uronic acid residues, which may be acetylated and sulfated; it accumulates in several mucopolysaccharidoses.

heparan sulfate

(hĕp′ə-răn)
n.
A glycosaminoglycan found on cell surfaces and basement membranes in mammals that regulates a wide variety of biological processes, including angiogenesis and blood coagulation. Also called heparitin sulfate.
