Whey protein
Whey protein is the collection of globular proteins that can be 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. Whey 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.In addition, whey protein is easily digestible.

Whey protein can be denatured by heat. High heat (like the sustained high temperatures above 72 degrees Celsius (160 degrees Fahrenheit) associated with the pasteurization process) denatures whey proteins, destroying some bioactive compounds, such as the amino acid cysteine. While native whey protein does not aggregate upon renneting or acidification of milk, denaturing the whey protein triggers hydrophobic interactions with other proteins, and the formation of disulfide bonds between whey proteins and casein micelles, leading to aggregation with other milk proteins at low pH.
Whey protein typically comes in three major forms: concentrate, isolate, and hydrolysate.

Concentrates contain a low level of fat and cholesterol but, in general, have higher levels of bioactive compounds, and carbohydrates in the form of lactose — they are 29%-89% protein by weight.
Isolates are processed to remove the fat, and lactose, but are usually lower in bioactive compounds as well — they are 90%+ protein by weight. Both of these types are mild to slightly milky in taste.
Hydrolysates are predigested, partially hydrolyzed whey proteins that, as a consequence, are more easily absorbed, but their cost is generally higher. Whey protein hydrolysate also tends to taste quite different than other forms of whey protein, usually in a way that many find undesirable but can be masked when used in beverages

Uses
More than other protein supplements, whey protein powder is commonly used by bodybuilders and other athletes to accelerate muscle development and aid in recovery. Some individuals with suppressed or otherwise abnormal immune systems or degenerative diseases use undenatured bioactive whey proteins to increase their antioxidant levels. Native whey proteins are a good source of cysteine, a conditionally essential amino acid, which is the rate-limiting factor for the body's production of glutathione, an important antioxidant.

In a study, it was found that whey supplements may prevent blood sugar spikes after high-carbohydrate meals, which is useful for diabetics.
As an athlete, you increase your need for protein with every set, rep, practice or big game. to make steady progress and gains, you must consume enough quality protein to push your body back into a state of positive nitrogen balance, is the perfect enviroment for muscle growth, recuperation and repair. used for muscle building, body building, gym, and all sports.
