mucic acid[′myü·sik ′as·əd]
(also saccharolactic acid, tetrahydroxyadipic acid), HOOC[CH(OH)]4COOH, a crystalline substance with a melting point of 213°C. The crystals are poorly soluble in cold water, alcohol, and ether. Mucic acid is formed as a result of the oxidation of galactose, and this reaction is used for the detection of galactose in various polysaccharides. The acid may be obtained from gum arabic and pectic substances, the consistency of which was the source for the name “mucic.” Mucic acid is used in the synthesis of pyrrole and other heterocyclic compounds.
