DEFINITION

Classification: 516/192

The compound is a carbohydrate* or carbohydrate-derivative*:

(under subclass 191) Subject matter in which the organic* compound which contains oxygen is a carbohydrate* or carbohydrate-derivative*, such as, monosaccharide or polysaccharide.

(1) Note. Carbohydrates are compounds which are saccharides whose monomeric units are polyhydroxy mono-aldehydes or polyhydroxy mono-ketones, having the formula C n(H 2O) n, where n is five or six, or the corresponding cyclic hemiacetals thereof. Carbohydrate-derivatives maintain the carbon skeleton and the carbonyl function or hemi-acetal function of the saccharide.
