2.4.1. Substances derived from monosaccharides

Substances derived from monosaccharides

The main substances derived from monosaccharides with biological interest are aminoglucids, resulting from substituting an alcoholic group  for an amino group.

The most important are the D-glucosamine, the N-acetyl - glucosamine, which polymerised form the chitin of the exoskeleton of arthropods and is involved in the formation of the bacterial wall, the N-acetyl-muramic acid , also present in the bacterial wall, and sialic acids present in glycoproteins and glycolipids of the cytoplasmic membrane.
