The word 'amino-degrading' is formed in English from 'amino' (referring to amino acids or compounds) and 'degrading' (from 'degrade', meaning to break down).

'Amino-degrading' is a modern scientific compound word, combining 'amino' (from Latin 'ammoniacum', referring to ammonia) and 'degrading' (from Latin 'degradare', meaning to reduce in rank or break down).

Initially, 'degrading' meant to lower in rank, but in scientific contexts, it evolved to mean 'breaking down chemically', and 'amino-degrading' specifically refers to breaking down amino compounds.
