Metabolite Identification
Common NameGDP-alpha-D-rhamnose
DescriptionGDP-alpha-D-rhamnose is a nucleotide sugar belonging to the class of glycosyl donors. Its chemical structure features a guanosine diphosphate (GDP) moiety linked to the sugar alpha-D-rhamnose, which is a 6-deoxy sugar. The identification of GDP-alpha-D-rhamnose was achieved through nuclear magnetic resonance spectroscopy, confirming its role as a product in specific biosynthetic pathways (PMID:11096116 ). This metabolite is involved in the biosynthesis of polysaccharides and glycoproteins, where it acts as a substrate for glycosyltransferases, facilitating the addition of rhamnose residues to growing carbohydrate chains. Additionally, GDP-alpha-D-rhamnose, along with other GDP-sugars like GDP-alpha-D-mannose and GDP-alpha-D-glucose, has been shown to exhibit strong inhibitory effects on certain enzymatic activities, indicating its potential regulatory roles in carbohydrate metabolism (PMID:213433 ). Overall, GDP-alpha-D-rhamnose serves as a critical component in the synthesis of complex carbohydrates, contributing to various cellular functions.
