Whey protein is a protein derived from whey, the liquid part of milk that separates from the curds during cheesemaking. It's a mixture of different proteins, primarily:
- α-lactalbumin: A protein that plays a crucial role in lactose synthesis.
- β-lactoglobulin: This protein is the most abundant in whey and is known for its ability to bind to and transport fatty acids.
- Serum albumin: This protein is important for maintaining blood pressure and volume.
- Immunoglobulins: These proteins are part of the body's immune system and help fight off infections.
While whey protein is primarily made up of these proteins, glycomacropeptide, which is not a protein but a complex sugar molecule, is also a significant component.
Whey protein is a popular supplement among athletes and fitness enthusiasts due to its high protein content, fast absorption rate, and potential benefits for muscle growth and recovery.
