Fucoxanthine

/ˌfjuːkoʊˈzænθiːn/ noun

Definition

An alternative spelling or variant form of fucoxanthin, the brown pigment in brown algae used in photosynthesis.

Etymology

Variant spelling of fucoxanthin with the chemical suffix -ine (an alternate form of -in). Both spellings appeared in early 20th century chemical nomenclature before standardization.

Kelly Says

The existence of both 'fucoxanthin' and 'fucoxanthine' shows how chemical naming evolved—older literature sometimes used -ine endings for plant pigments, creating variant spellings that scientists gradually standardized.
