Which of the following is a milk protein?

Correct option is D

The correct answer is (d) Casein.
· Casein is the primary protein found in milk and dairy products.
· It accounts for nearly 80% of the protein content in cow's milk and is an important source of essential amino acids.
· Casein is known for its slow-digesting properties, making it ideal for providing a sustained release of amino acids.
· It is widely used in food production and nutritional supplements.
Additional Knowledge:
· Galactose: A sugar found in milk, formed from the breakdown of lactose, not a protein.
· Rennin: An enzyme that helps in milk digestion by curdling milk, especially in young animals, but it is not a protein itself.
· Glycine: An amino acid found in various proteins, but it is not specific to milk protein.
