Glycobiology

Mucopolysaccharidoses are inherited disorders in which inactivation of lysosomal enzymes results in accumulation of glycosaminoglycans within cells, causing tissue and organ dysfunction. A method to determine the unique end structures of the accumulated glycosaminoglycans offers a new way for diagnosis.
