Hydrolysate refers to any product of hydrolysis. Protein hydrolysate has special application in sports medicine because its consumption allows amino acids to be absorbed by the body more rapidly than intact proteins, thus maximizing nutrient delivery to muscle tissues. It is also used in the biotechnology industry as a supplement to cell cultures.
Whey Protein Hydrolysate 
Unlike concentrate or isolate forms of whey protein, hydrolysates are enzymatically predigested for maximal speed of absorption. This additional processing often comes at an increased cost, but is considered superior for post-workout muscle hypertrophy. Additionally, some individuals who experience intestinal problems with WPC or WPI may not experience problems when consuming hydrolysate.
Whey protein hydrolysate is distinct from hydrolyzed collagen. Hydrolyzed collagen is produced from collagen found in the bones, skin, and connective tissue of animals. The amino acid content of hydrolyzed collagen is the same as collagen, which is deficient in one of the nine essential amino acids. This distinguishes hydrolyzed collagen from whey protein hydrolysate, which is derived from the whey protein fractions of cow's milk. Whereas hydrolyzed collagen is often used to improve skin, bone, and joint health, it is not typically used for weight training because it does not contain all of the essential amino acids.
