Muramic acid

(2R)-2-{[(2R,3R,4S,5S,6R)-3-amino-2,5-dihydroxy-6-(hydroxymethyl)oxan-4-yl]oxy}propanoic acid

C9H17NO7 (251.1005)


Muramic acid is an amino sugar acid. In terms of chemical composition, it is the ether of lactic acid and glucosamine. It occurs naturally as N-acetylmuramic acid in peptidoglycan, whose primary function is a structural component of many typical bacterial cell walls. Muramic acid, also known as muramate or murexide, belongs to the class of organic compounds known as sugar acids and derivatives. Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. Muramic acid is an amino sugar acid. It occurs naturally as N-acetylmuramic acid in peptidoglycan, whose primary function is a structural component of many typical bacterial cell walls. In terms of chemical composition, it is the ether of lactic acid and glucosamine. Muramic acid is a marker of bacterial peptidoglycan, in environmental and clinical specimens.

Fructose aminoacids are naturally occurring compounds derived from D-fructose and L-aminoacids. They are amadori products resulting from sugar-aminoacid interactions in food products, especially cooked foods [CCD]. N-(1-Deoxy-1-fructosyl)alanine is found in green vegetables and root vegetables. N-(1-Deoxy-1-fructosyl)alanine is found in green vegetables. N-(1-Deoxy-1-fructosyl)alanine is classified as a Natural Food Constituent (code WA) in the DFC.
