DEFINITION

Classification: 527/305

With aldehyde or derivative as a reactant other than as an aldose:

(under subclass 300) Subject matter wherein an aldehyde or derivative (other than an aldose) is present in addition to the carbohydrate or derivative.

(1) Note. The aldose sugars are carbohydrates, but their presence alone is not sufficient for this subclass since another aldehyde must be present.
