digestion of proteins Flashcards
1
Q
how are proteins broken down
A
by a combination of different peptidases
2
Q
what do peptidases do
A
catalyse proteins into amino acids by hydrolysis the peptide bonds between amino acids
3
Q
what are endopeptidases
A
enzymes that act to hydrolyse peptide bonds within a protein
4
Q
what are exopeptidases
A
enzymes that act to hydrolyse peptide bonds at the ends of protein
5
Q
what do exopeptidases do
A
remove single amino acids
6
Q
what are dipeptidases
A
exopeptidases that work specifically on dipeptides
7
Q
what do dipeptidases do
A
act to separate two amino acids that make up a dipeptide by hydrolysing peptide bond
8
Q
where are dipeptidadses located
A
cell membrane surface of epithelial cells in small intestine
