glyceraldehyde

/ˌɡlɪs.əˈræl.də.haɪd/

Definition

A simple sugar molecule consisting of three carbon atoms that serves as a fundamental building block in prebiotic chemistry.

Etymology

The name is a blend of 'glycerol,' referring to the sweet, syrupy alcohol it is derived from, and 'aldehyde,' the chemical functional group it contains. It was first synthesized in the 19th century by oxidation of glycerol.
