Etymology
The word 'glycine' is a modern scientific coinage derived from the Greek root 'glykys', meaning 'sweet', due to the compound's sweet taste. The suffix '-ine', commonly used in chemical nomenclature, was appended to denote it as a nitrogenous base or amino acid. This construction follows the pattern of naming organic substances based on a key property (sweetness) and their chemical class. Thus, the literal "sweet substance" accurately describes the sensory characteristic that led to its identification and naming.
