ʻO ka Peptide kahi mea biochemical ma waena o ka amino acid a me ka protein. ʻOi aku ka liʻiliʻi o ke kaumaha ma mua o ka protein, akā ʻoi aku ka nui o ke kaumaha ma mua o ka amino acid. He ʻāpana o ka protein. ʻO ia hoʻi, mai ka ʻoi aku o ʻelua a i ʻole ka nui o nā amino acid peptide bond polymerization i loko o kahi peptide, a laila mai nā peptides lehulehu me nā kaulahao ʻaoʻao polymerization i loko o kahi protein. ʻAʻole hiki ke kapa ʻia ka ʻakika amino he peptide, pono e ʻoi aku ma mua o ʻelua mau waikawa amino i hoʻopili ʻia e kahi hui kaulahao peptide e kapa ʻia he peptide; ʻAʻole i kapa ʻia ka nui o nā waikawa amino i hui pū ʻia he peptides; Pono e hoʻopili ʻia nā ʻakika amino e nā mea paʻa peptide, e hana ana i "chain acid amino", "string amino acid", hiki ke kapa ʻia ke kaula o nā waikawa amino he peptide. .
