Aspartylglycosamine, also known as n4-(beta-N-acetyl-D-glucosaminyl)-L-asparagine or 1-beta-aspartyl-N-acetyl-D-glucosaminylamine, is a member of the class of compounds known as glycosylamines. Glycosylamines are compounds consisting of an amine with a beta-N-glycosidic bond to a carbohydrate, thus forming a cyclic hemiaminal ether bond (alpha-amino ether). Aspartylglycosamine is soluble (in water) and a moderately acidic compound (based on its pKa). Aspartylglycosamine can be found primarily in urine, as well as in human spleen tissue. Within the cell, aspartylglycosamine is primarily located in the cytoplasm. Moreover, aspartylglycosamine is found to be associated with aspartylglucosaminuria, which is an inborn error of metabolism. Large amount of aspartylglycosamine appears in patients with aspartylglycosaminuria corresponding to decreased activity of aspartylglycosamine amido hydrolase. Large amount of aspartylglycosamine appears in patients with aspartylglycosaminuria, which is a metabolic disorder associated with decreased activity of aspartylglycosamine amido hydrolase. [HMDB]
