the molecular receipt your cells leave behind, proving every chemical transaction they ever made
means A metabolite is any small molecule produced or consumed during metabolism — the intermediate or end product of your body's chemical reactions.
from From the Greek 'metabolē,' meaning 'change' (literally 'a throwing beyond,' from 'meta-,' beyond, plus 'ballein,' to throw) — the same root that gives us 'metabolism.' The '-ite' ending is the chemist's habitual suffix for naming a substance or product. So a metabolite is, quite plainly, the thing produced by change — a word assembled in the 19th-century language of biochemistry as scientists began tracing exactly what the body's reactions left behind.
