Whey Protein: What Is It?

 

 

Whey proteins are globular proteins that can be isolated from whey. Generally, this collection of proteins are a mixture of:

• beta-lactoglobulin (66%);
• alpha-lactalbumin (26%); and,
• serum albumin (8%).

Approximately 10% of the dry solids in whey make up the protein components of whey. These may be broken down into four major protein fractions: beta-lactoglobulin; bovine serum albumin; alpha-lactalbumin; and, immunoglobulins. These proteins possess significant disease-fighting abilities. Additionally, whey comprises six minor protein fractions.

 

 

Whey Protein Powder: Why Proteins From Whey Are Good For You

 

 

Powder from whey protein is the most commonly used protein supplement used by bodybuilders and other athletes. Whey protein powder is used to accelerate the development of muscles in addition to aiding in the body's recovery.

 

In order to increase their antioxidant levels, individuals with degenerative diseases, suppressed or abnormal immune systems ingest undenatured whey proteins for their source of cysteine (a conditionally essential amino acid that is the rate limiting factor for the body's production of glutathione, an important antioxidant.

 

 

 

 

 

With the strengthening of the body's immune system, whey protein powder has been found to enhance the consumer's skin, hair and nails as well.

 

When combined with a healthy diet and regular exercise, protein powder from whey has been found to consistently and noticeably increase muscle growth by stimulating the amino acids responsible for muscle endurance, enhancement and growth and also assists in reducing muscle deterioration.

 

 

 

 

 

 

 

 

Forms of Whey Protein

 

 

Typically whey protein is found in three major forms: concentrate, hydrolysate and isolate.

 

Whey Protein Concentrate: Containing higher levels of bioactive compounds and carbohydrates in the form of lactose, concentrates of whey protein contain a low level of fat and cholesterol and are 29% to 89% protein by weight.

 

Whey Protein Hydrolysate: Easily absorbed due to being predigested, hydrolyzed whey protein tends to be higher in cost. Due to the processing, many find the taste of whey protein hydrolysate to be less than desirable and thus this type of whey protein is commonly found in beverages or powders mixed with flavours that mask the taste.

 

Whey Protein Isolate: Processed to remove the fat and lactose, isolate whey proteins are also lower in bioactive compounds as well and are usually over 90% protein by weight.

 

 

 

 

 

 

 

Protein from whey, a complete protein containing all of the essential amino acids required for muscle growth and repair from stressful events such as endurance training and resistance training.
