Which type of protein is found in milk?
- APepsin and lipase
- BChymotrypsin
- CTrypsin and amylase
- DCasein and whey protein
Solution & Step-by-step Explanation
Milk consists of two main types of high-quality proteins:
Casein: Makes up about 80% of the total protein Content in cow's milk and clots or curdles in acidic conditions.
Whey protein: Makes up the remaining 20% of milk protein and remains soluble in the liquid part after milk curdles.
Pepsin, trypsin, chymotrypsin, and lipase are digestive enzymes, not native milk proteins. Amylase is a carbohydrate-digesting enzyme.
