Rennin in infants digests which substance?

Explanation:
In infants, a stomach enzyme called rennin acts on the milk protein in what the baby drinks. It specifically targets casein, causing the milk to coagulate into a solid curd. This curdling slows milk’s passage and makes the protein easier to digest with other enzymes later on. So the substance rennin works on is milk. Starch, fats, and other proteins in general are handled by different enzymes, but rennin’s role in infancy is the coagulation of milk protein.
