Whey Protein is a type of protein that can be used by both men and women for different things. Whey protein is the collection of globular proteins isolated from whey, a by-product of cheese manufactured from cow’s milk. It is typically a mixture of beta-lactoglobulin (~65 %), alpha-lactalbumin (~25 %), and serum albumin (~8 %), which are soluble in their native forms, independent of pH. The protein fraction in whey (approximately 10 % of the total dry solids within whey) comprises four major protein fractions and six minor protein fractions. The major protein fractions in whey are beta-lactoglobulin, alpha-lactalbumin, bovine serum albumin and immunoglobulins.
