Whey protein as defined by Wikipedia, as the collection of globular proteins that can be isolated from whey, a by-product of cheese manufactured from cow's milk. Whey or milk plasma is the liquid remaining after milk has been curdled and strained; it is a by-product of the manufacture of cheese or casein and has several commercial uses. It is typically a mixture of beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%). These are soluble in their native forms and has an independent ph. Whey as compared to other sources of protein like egg and meat, has the highest biological value (BV) of any known protein.
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. Each of these components has important disease-fighting effects.
Forms of Whey Protein
The three major forms of whey protein comes in concentrates, isolates, and hydrolysates. Knowing the different characteristics of these proteins can help an athlete or a bodybuilder in choosing the right kind of whey protein he must take.
Concentrates contain a low level of fat and cholesterol. In general,concentrates have higher levels of bioactive compounds, and carbohydrates in the form of lactose. It contains 29%-89% protein by weight.
Isolates are processed to remove the fat content and lactose. Isolates are usually lower in bioactive compounds as compared to concentrates. They are 90%+ protein by weight. It taste mild to slightly milky which is more preferred by most users. Whey protein isolate has approximately 50% more leucine than soy protein isolate. It is considered as the best protein.
Hydrolysates are easily absorbed and are predigested. These are partially hydrolyzed whey proteins that can be easily absorbed by the body. Hydrosylates cost higher than the other forms of protein. It tastes different from other types but it tastes better when used with beverages.
