What is Whey Protein
Whey protein is actually a term used to describe a group of globular proteins that can be separated from whey. When cow’s milk is used to manufacture cheese, it also leads to the production of whey, which may or may not be discarded. It is a mixture of lactoglobulin, alpha-lactalbumin and serum albumin.
Similar to protein found in egg white, whey protein can also be irreversibly changed by heat. When made part of the pasteurization process, it becomes less bio-active. If not, whey protein naturally becomes bio-active which basically means it contains a high concentration of cysteine and consequently glutathione, an antioxidant that is essential to improved fitness and health.
