DEFINITION

Classification: 536/1.11

Carbohydrates or derivatives:

(under the class definition) Compounds which are saccharides whose monomeric units are polyhydroxy mono-aldehydes or polyhydroxy mono-ketones having the formula Cn(H2O)n (wherein n is five or six) or the corresponding cyclic hemiacetals thereof; or the reaction derivatives thereof in which the carbon skeleton and the carbonyl function or hemi-acetal function of the saccharide unit are not destroyed.

(1) Note. Carbohydrate degradation products which contain fewer than five carbon atoms are not provided for in this or indented subclasses, but are in appropriate subclasses in classes in the 532-570 series.

(2) Note. Alcohol, acid, and amine derivatives of carbohydrates which are formed by the alcohol, acid, or amine function replacing the oxygen of the carbonyl group of the carbohydrate are classified in the appropriate alcohol, acid, and amine subclasses in Classes 568, 562, and 564, respectively.
