Beta-lactoglobulin

• Whey protein is made up of 65 percent beta-lactoglobulin. This molecule exists mainly to provide food and energy to the other parts of our cells. Cells need energy to transport protein, waste and synthesize reactions. In order for the whey powder to work quickly and efficiently, the supplement must provide more food for the cells to work faster.
  
  

Alpha-lactalbumin

• Whey protein is made up of 25 percent alpha-lactalbumin. This molecule increases the production of lactose. Lactose is a sugar found in milk. By providing more of this type of sugar, the body has more energy to repair damaged muscles faster. By working out, you literally destroy the muscular tissue. The body sends its own protein to repair the damage. By adding this extra protein to your body, you are helping the repair process.
  
  

Serum Albumin

• Whey protein is made up of 8 percent serum albumin. This molecule ensures that your blood vessels maintain a high level of pressure. The goal of whey powder is to repair your muscles as quickly as possible. By making sure your blood vessels are open and flowing freely, the protein can be delivered faster.
  
  

Immunoglobulins

• Whey powder contains immunoglobulins, or antibodies, which protect your body from foreign objects such as bacteria and viruses. Working out puts your body at a higher risk for infections. The body becomes preoccupied with repairing the damage being done to muscles. Foreign objects have more opportunities to infiltrate your immune system. By taking whey powder, you introduce an extra form of protection against a potential illness.
