What is Whey Protein?

The process of acidifying milk brings both a solid part, called the curd, and a liquid part called whey. The whey component can be turned into powder by water removal, and sold to the muscle craving persons around the world. Whey protein is among the most easily absorbed and convenient forms of protein available for fitness enthusiasts who want to get muscles fast.

However, many fitness freaks don’t realize that there are four major forms of protein that are offered by every whey protein supplier.

Following is a synopsis of those four major types of whey protein.

Concentrate:

This is a major form of whey protein and is a byproduct of the cheese manufacturing process. It varies in potency from 29%-89% protein by weight. The concentrate is relatively low in fat and cholesterol than other forms of protein. It’s crucial to note because concentrate is the least processed protein and is typically has the highest level of bioactive compounds, and carbohydrates in the form of lactose.

An array of scientific case studies and literature have acknowledged a relationship between protective effects and bioactive compounds against several adverse health conditions. The conditions include cardiovascular disease, hypertension, and cancer.

Isolate:

The second significant form of protein isolates and is usually carries 90%+ protein by weight. It is typically lower in bioactive compounds.

Whey protein isolate is among the purest forms of protein as a staple for many fitness freaks who look to build lean muscle mass. Since everyone’s body is unique; therefore, if you are intolerant to lactose, it is recommended to start with small amounts to start with.

As always, the best practice is to consult your trainer or physician before beginning any new exercise, or nutrition plan. A drawback of the refined nature of isolates is that it happens to be a bit pricier compared to whey protein concentrate.

Hydrolysates:

This type is known as protein hydrolysates that are predigested, or partially hydrolyzed whey proteins. The procedure of hydrolyzation uses enzymes to dissociate the protein strands into smaller chains called peptides. Peptides, in turn, permits them to travel through the digestion process more quickly. As a processed protein compare to concentrate or isolate, it is quite potent and is rapidly absorbed.

It is found that it’s common to discover hydrolysates in a blended form. However, it is generally slightly harder to find in a pure form compared to isolate and concentrate. It is also vital to note that highly-hydrolyzed whey is supposed to be less allergenic to those with milk allergies than other types of whey. That is why it is commonly known as a component in infant formula. As among the most processed and pure whey, it’s generally the highest-priced protein than other major forms of whey protein.

Casein:

Out of the protein found in milk, approximately 20% is whey protein, and the remaining 80% is casein. An attractive molecular feature of casein is its capability to clot in the stomach. As a result, it makes it a protein that liberates amino acids into the bloodstream slower and for an extended time. Whereas the rate of release following ingestion of whey isolate seems to decline after 2 hours or so. This property makes casein a useful protein to incorporate into the fitness program diet when a slow release of amino acids is desirable, such as in the evening hours before you are going into the night.
