Common NameUDP-alpha-D-galacturonic acid
DescriptionUDP-alpha-D-galacturonic acid is a nucleotide sugar that belongs to the class of uridine diphosphate sugars. Chemically, it is characterized by the presence of a uridine moiety linked to alpha-D-galacturonic acid, which is an acidic monosaccharide derived from galactose. The structure features a uridine diphosphate group attached to the anomeric carbon of the galacturonic acid, facilitating its role in glycosylation reactions. UDP-GalA serves as a crucial precursor for the synthesis of various bacterial and plant polysaccharides, contributing to the formation of structural components such as pectin in plant cell walls (PMID:19564155 ). Additionally, UDP-GlcA 4-epimerase (UGlcAE) is an enzyme that catalyzes the conversion of UDP-alpha-D-glucuronic acid to UDP-alpha-D-galacturonic acid, highlighting its metabolic interconversion within carbohydrate metabolism (PMID:15563616 ). This nucleotide sugar is integral to polysaccharide biosynthesis pathways, underscoring its importance in both plant and microbial biology.
