Ngokumalunga nobudala, umphumo wabantu abadala udla ngokuba ngcono kunolutsha; Ukususela kwinqanaba lempilo, abantu abagulayo badla umphumo we-peptide. Umntu osempilweni. Ngokuphathelele ukudinwa, abantu abadiniweyo benza ngcono kunabanye; Abantu ababetyando benza ngcono ngeepeptides kunabantu abangazange benze utyando... Ngenxa yokuba iipeptides zinexabiso eliphezulu lesondlo, kulula ukufunxa, ukunciphisa umthwalo wendlela yokwetyisa, ukukhuthaza ukuphiliswa kwenxeba kunye neempawu ezichasene nokudinwa, ngoko ke kuyafana neyeza elichanekileyo, xa abantu bekwimo yefiziyoloji, bafuna iipeptides ezinemisebenzi eyahlukeneyo ukuze zincedisane.
