Protein digestion in the human gut involves hydrolysis of peptide bonds by endopeptidases breaking down polypeptides into smaller peptide chains, exopeptidases removing terminal amino acids, and dipeptidases breaking down dipeptides into amino acids.
A digestão de proteínas no trato digestivo humano envolve a hidrólise de ligações peptídicas por endopeptidases que quebram polipéptidos em cadeias de péptidos menores, exopeptidases que removem aminoácidos terminais e dipeptidases que quebram dipeptídeos em aminoácidos.
