Terms & Properties

Preferred Name: Whey Protein Isolate

Definition: A biologically active, cystine-rich, whey-based protein isolate. Whey protein isolate is broken down in the body into cystine and glutamylcystine, which travel safely in the blood stream, upon cell entry, deliver a sustained amount of free cysteine to the cells. The available cysteine allows cells to synthesize glutathione (GSH), a tripeptide containing amino acids glycine, glutamate and cysteine, thereby maintaining and increasing intracellular GSH concentrations. GSH plays a major role as an antioxidant, thereby protecting cells from oxidative damage due to harmful substances such as free radicals and reactive oxygen compounds.

NCI-GLOSS Definition: A powdered form of proteins taken from whey, which is the liquid left over when cheese is made from cow's milk. Whey protein powder is used to increase protein in the diet and is being studied for possible health benefits.
