joined by peptide bond(s)
Etymology
'peptide-linked' is a modern English compound formed from 'peptide' + 'linked'. 'peptide' originates from Greek, specifically the element 'peptid-' from the Greek πεπτίδιον (peptidion), where the root πεπτέν/πεπτεῖν (peptein) meant 'to digest'. 'linked' is the past-participle form of 'link', which derives from an old Germanic root meaning 'to bind or connect.'
'peptide' was adopted into scientific vocabulary in the late 19th to early 20th century (via Neo-Latin/German/French scientific usage) to denote short chains of amino acids; 'link' evolved from older Germanic words for connection and became the modern English verb 'link', so the compound 'peptide-linked' arose in modern scientific English by combining these elements.
Originally the Greek root behind 'peptide' related to digestion, but in modern scientific usage 'peptide' came to mean a short chain of amino acids; accordingly, 'peptide-linked' now specifically means 'joined by peptide bonds' rather than anything relating to digestion.
