Question
Which of the following enzymes carries out initial step in the digestion of milk in humans?
-
Rennin
-
Lipase
-
Trypsin
-
Pepsin
Solution
D.
Pepsin
In human milk protein digesting enzyme in stomach is pepsin.In calves it is renin.It is alos present in small amounts in human infants but not adults. Pepsin acts on water soluble 'caseinogen (milk protein) to form soluble 'casein'. This combines with calcium salts to form insoulble calcium paracaseinate, which gets readily digested enzymatically.
