addtheose
addtheose is a hypothetical term referring to a class of organic compounds that are five-carbon aldoses. The "aldo" prefix indicates the presence of an aldehyde functional group, and "ose" is a common suffix for carbohydrates. Therefore, addtheose molecules possess a chain of five carbon atoms with a terminal aldehyde group and hydroxyl groups on the remaining four carbons.
The simplest addtheose is D-ribose, a fundamental component of ribonucleic acid (RNA). Other important addtheoses include
The stereochemistry of the hydroxyl groups on the carbon chain defines different isomers of addtheose. D-isomers
