Pronunciation

Etymology

It is formed from English bio- + chemistry,[2][3][4][5] after biochemical, recorded from 1836, and slightly later than biochemist (1845).[2] Merriam-Webster treats it as an international scientific word, originally formed as German Biochemie;[6] the OED compares the German word, recorded from 1813 or earlier, and French biochimie (1838).[2] The prefix bio- is from Ancient Greek βίος (bíos, “life”).[3]

Earliest recorded meaning

The branch of science concerned with the chemical substances and processes of living organisms: first recorded in 1848, in The Lancet.[2][6] Etymonline dates the word, also written bio-chemistry, to 1857,[3] and Dictionary.com to 1880–85.[5]

Semantic evolution

The adjective came first: Etymonline dates biochemical to 1840, after German biochemisch,[3] and the OED to 1836.[2] From 1881 biochemistry was also the name of a system of alternative medicine related to homeopathy, which aimed to keep or restore the balance of the mineral constituents of the body; it was taken from the German Biochemie of W. H. Schüssler, whose work was translated that year.[2] The main sense has always been the scientific one, the chemistry of plant and animal life.[6][2]
