Glucuronic acid is a sugar acid derived from glucose, with its sixth carbon atom oxidized to a carboxylic acid. In living beings, this primary oxidation occurs with UDP-α-D-glucose (UDPG), not with the free sugar. Glucuronic acid, like its precursor glucose, can exist as a linear (carboxo-)aldohexose (<1%), or as a cyclic hemiacetal (furanose or pyranose). Aldohexose… WebMay 11, 2024 · GlcUA, glucuronic acid; Rha, rhamnose. ... To test for phosphodiester bonds, CPS–PG was subjected to digestion by 48% hydrofluoric acid (HF).
