galactosamine

 [gah-lak″to-sam´in]
an amino derivative of galactose.

ga·lac·tos·a·mine

(gă-lak'tō-sam'ēn),
The 2-amino-2-deoxy derivative of galactose, in which the NH2 replaces the 2-OH group; the d-isomer occurs in various mucopolysaccharides, notably of chondroitin sulfuric acid and of B blood group substance; usually found as the N-acetyl derivative.
