Chemical Information
FooDB NameUDP-D-Xylose
DescriptionUDP-D-Xylose, also known as UDP xylose or UDP-alpha, belongs to the class of organic compounds known as methionine and derivatives. Methionine and derivatives are compounds containing methionine or a derivative thereof resulting from reaction of methionine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. UDP-D-Xylose is an extremely weak basic (essentially neutral) compound (based on its pKa). UDP-D-xylose can be biosynthesized from uridine diphosphate glucuronic acid through its interaction with the enzyme UDP-glucuronic acid decarboxylase 1. In humans, UDP-D-xylose is involved in the metabolic disorder called galactosemia II (galk).
