What is a whey protein hydrolysate?

It is whey protein that has been hydrolyzed---which means it is sliced into smaller pieces by enzymes. What is hydrolysis? It is the process of enzymatic breakdown of protein, normally conducted in the GI tract (stomach and small intestine). Enzymatic hydrolysis can also be performed outside the human body, and this is how whey protein hydrolysates are processed. Food-grade enzymes are introduced to whey protein concentrate or isolate thus reducing the size of the protein molecules, called peptides. Is hydrolysis necessary? Yes. It is critical to absorption. All dietary protein must be reduced (hydrolyzed) to the smallest peptides called di and tripeptides, or free form aminos in order to be absorbed by the body (muscles, organs, etc). If you consume protein that is not hydrolyzed, like isolates, concentrates, blends, caseins, soy and caseinates, it must be hydrolyzed in your GI tract (stomach and small intestine). Whatever protein is not hydrolyzed down to di and tripeptides or free form aminos may not be transported into the blood for distribution to your muscles and other tissues. It will travel on into the colon where it is not absorbed and becomes food for bacteria. BNRG's exclusive DTP technology insures complete hydrolysis and absorption.*

How can I tell if a product has an effective level (High-DH) of hydrolysis?

The best test is to find out the percent of di and tripeptides. A High-DH will have over 30% to 40% di & tripeptides. Proto Whey has on average 40% di and tripeptides, which produces an AMW of less than 1,000 daltons. Just as important, a top quality High-DH, biologically-efficient protein product like Proto Whey contains low concentrations of amino acids; levels under 3-5% free form aminos. Some products attempt to deceive the consumer by reducing their average molecular weight tests by adding large amounts of free form aminos. This is not what a true High-DH hydrolysate protein is. Adding amino acids to a true High-DH product is a waste and. Also, check the ingredient listing to see if free form aminos are added, and for the inclusion of whey protein hydrolysates in the number one spot (although this will not tell you the DH of the hydrolysate).

Why are di and tripeptides a better form of protein nutrition than free form aminos?

Generally speaking the human body prefers di and tripeptides as the predominant source of absorbed protein. Certain tissues such as the brain, lungs and kidneys have a direct need for di and tripeptides. Furthermore, protein absorbed as di and tripeptides is not metabolized by the liver in the same way circulating amino acids are metabolized. Particularly large doses of free form amino acids (other than BCAAs, which normally by-pass first pass hepatic metabolism) directly absorbed from the gut. The di and tripeptides absorbed into the blood are utilized for protein synthesis at a higher rate.* Once absorbed, the di and tripeptides are not transaminated or deaminated by the liver to the same extent as circulating amino acids. The liver limits the amount of free aminos that can be in the blood at any one time, so large spikes in amino acids being absorbed from the gut after a heavy protein meal (containing over 20g protein) increases amino acid oxidation, which converts precious amino acids into energy rather than protein. Di and tripeptides do not have this limitation because they have their own high-throughput transporter (PEPT-1), so protein absorption is not limited in this way - a huge value to any athlete attempting to absorb large amounts of protein necessary for peak recuperation and muscle building.* In addition di and tripeptides utilize PEPT1 and PEPT2 transporters exclusively whereas free form aminos do not. Free amino acids use many low-throughput high-specificity amino acid transporters. Recent studies that measure the effects of di & tripeptides on their transporter systems (PEPT-1 particularly) have suggested that higher concentrations of di & tripeptides in the upper small intestines up-regulates the intestine's ability to consume more protein by increasing the density of PEPT-1 transporters in the upper intestine.* Other recent studies have suggested that the high utilization of these transporters may up-regulate virtually all metabolic functions that rely on protein such as muscular repair and neurological function.* I have heard that some proteins are fast and some are slow such as whey concentrate and isolate, casein, and blends which claim to have both.
