What is whey protein?

Whey protein is a co-product of the cheese making process; it is the name for a collection of globular proteins that can be isolated from whey, a by-product of cheese manufactured from cow's milk. It is typically a mixture of beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%), which are soluble in their native forms, independent of pH. Whey has the highest biological value (Isolated Whey =100 and Whey protein concentrate =104)of any known protein. Whey is a component of milk. Simply put, it's the protein that remains after the cheese-making process uses, up casein molecules. There are other specific points: Liquid milk contains about 6.25% protein. Of that protein, 80% is casein and the remaining 20% is whey.

Whey is a complete protein, featuring all essential and non-essential amino acids. Whey also contains the highest concentrations of BCAAs for any protein in nature. (BCAAs comprise 47.5-50.5% of the essential amino acid profile of a good whey protein.) . Whey is comprised of nitrogen-containing compounds. The amounts of these globular protein fractions depend upon breed of cow, time of year, type of feed, country of origin, and lactation cycle of the animal. . These many variables add up to a wide-ranging diversity of protein fraction percent-ages and amino acid profiles among different whey protein powders. The type and quality of processing (filtering, ion exchange, heat temperature, acids or enzymes) explain other variations.

Whey Protein is composed of Four Main Fractions and Six Minor Fractions:

• Major Fractions % in Whey Molecular Weight (MW)
• Beta -lactoglobulin 46- 57% 18,400- 36,800 Daltons
• Alpha-lactalbumin 12 - 25% 69,000 Daltons
• Bovine serum albumin Approx. 10%' 69,000 Daltons
• Immunoglobulins Approx 10% 15,00 - 16,000 Daltons

How is whey protein made?

Whey protein is a co-product of the cheese making process. Listed below is a brief description of the steps involved in making BiPro pure whey protein isolate.
Steps

• Fresh milk is tested, approved by Quality Assurance experts and pasteurized.
• The casein, or "curd", and a portion of the milk-fat are separated out to make cheese.
• The remaining liquid whey goes through a series of fine, specialty filters to separate the whey protein from the lactose and other ingredients in the liquid whey.
• Concentrated liquid whey enters an ion exchange tower to further concentrate and purify the whey protein. Ion exchange is a gentle process and does not denature, or "break down", the whey protein.
• Next, the product enters a drying tower to remove water.
• The final step is to package the pure whey protein isolate powder into various size containers for use.

What are the benefits of whey protein?

• Compared to other proteins, on a gram-to-gram basis whey protein isolate delivers more essential amino acids to the body but without the fat or cholesterol.
• Whey protein concentrate also was found to be a potent inhibitor of oxidized low density lipoprotein cholesterol. Current research suggests that the conversion of LDL to oxidized LDL is the trigger that leads to atherogenesis(blocking the blood supply to heart)... the formation of the plaque and lesions associated with atherosclerosis.
• The body requires more energy to digest protein than other foods (thermal effect) and as a result you burn more calories after a protein meal.
• Whey powder is commonly used by bodybuilders and athletes desiring to accelerate muscle development and aid in recovery,to Repair body cells ,Build muscles and to Provide a source of energy.
• Whey protein isolate is pure protein with little to no fat or carbohydrates. It is a perfect complement to any low carbohydrate or low glycemic index diet plan.
• Protein helps to stabilize blood glucose levels by slowing the absorption of glucose into the bloodstream. This in turn reduces hunger by lowering insulin levels and making it easier for the body to burn fat.
• Whey protein contains bioactive components that help stimulate the release of two appetite-suppressing hormones: cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1).
• Whey protein intake improves nitrogen balance; Nitrogen balance refers to the condition in which the amount of dietary nitrogen intake is equal to the amount of nitrogen excreted. If the nitrogen balance is positive, this indicates that there may be a net growth in body tissues.

What Are The Side Effects of Taking Whey Protein?

There are no documented side effects provided a person does not have an allergy to dairy proteins or is lactose intolerant. If you have a dairy protein allergy please consult your physician before taking whey protein. If you are lactose intolerant choose a whey protein isolate which contains trace amounts of lactose, if any. Whey protein is a complete high quality protein and should be an acceptable protein source also for healthy pregnant women and children provided they are not allergic to dairy proteins. The second most abundant component in whey protein is alpha-lactalbumin, which is one of the main whey proteins in human breast milk. Infant formulas, including those for premature infants, often include whey protein. Whey protein is an easily soluble, very easy to digest protein.
