(amino-cleave)
split / remove amino link
Etymology
'amino-cleaving' is a modern compound formed from the combining form 'amino-' (from 'amine') and the present participle 'cleaving' (from the verb 'cleave').
'amino-' was coined in chemical nomenclature in the 19th century from 'amine' (itself from French 'amine'), while 'cleave' derives from Old English 'cleofan' meaning 'to split'; the two elements were joined in modern scientific English to describe actions on amino groups or bonds.
Initially 'cleave' meant 'to split or separate'; combined with the chemical prefix 'amino-' it evolved into the specialized technical sense of 'splitting or removing amino groups / breaking amino-containing bonds' in biochemistry.
