'antiproteolysis' originates from Greek/modern scientific formation, specifically the prefix 'anti-' (Greek 'anti') meaning 'against', and 'proteolysis' (from Greek 'proteo-' meaning 'protein' and 'lysis' meaning 'loosening, dissolving').

'antiproteolysis' was formed in modern scientific/biochemical English by adding the prefix 'anti-' to the existing term 'proteolysis' (itself from Greek roots 'proteo-' + 'lysis'), producing the meaning 'against proteolysis'.

Initially, 'lysis' (from Greek) meant 'loosening' or 'dissolution', and 'proteolysis' came to mean 'the breakdown/digestion of proteins'; 'antiproteolysis' was later coined to denote the prevention or inhibition of that breakdown.
