L-Pentaguluronic acid（Cat No.:I044865）is a rare uronic acid derived from L-pentose sugars, structurally characterized by a five-carbon backbone with a terminal carboxylic acid group. Though less common than hexuronic acids like glucuronic or guluronic acid, it may occur as a degradation product or intermediate in specific biochemical or synthetic pathways. Its potential role in carbohydrate metabolism and structural polysaccharides is of interest in glycoscience. L-Pentaguluronic acid’s functional groups allow for hydrogen bonding and metal coordination, making it a candidate for exploring bioactive polymer design, analytical chemistry, and niche biochemical applications.
