Etymology
'trypsin-resistant' is a compound of 'trypsin' and 'resistant'. 'trypsin' was coined in scientific Latin/English in the 19th century from Greek roots (from tryptein/'trypein' meaning 'to rub' or 'to wear away') via Modern Latin 'trypsinum' for the proteolytic enzyme; 'resistant' comes from Latin 'resistere' meaning 'to stand back' or 'to withstand', entering English via Old French and Latin-derived forms.
'trypsin' was formed in modern scientific usage (Modern Latin 'trypsinum' from Greek 'tryptein'), and 'resistant' entered English from Latin 'resistere' through Old French; the compound 'trypsin-resistant' was created in modern scientific English by combining these elements to describe resistance to the enzyme.
Initially the compound simply described the ability to 'withstand trypsin' in a literal biochemical sense; over time it has remained a technical term used in biology and biochemistry to denote materials, proteins, or organisms not cleaved or inactivated by trypsin.
