A steroid alcohol compound found in or derived from flower tissues, related to plant sterols.
Formed from 'anthos' (flower) combined with 'sterol' (a class of organic compounds), with the suffix '-in' indicating a chemical compound. This term appeared in biochemistry literature in the early 20th century.
Plants produce sterols just like animals do, and finding them in flowers specifically led scientists to study whether flowers have special biochemical roles beyond reproduction—spoiler alert, they do!
