Immune Function. Your immune system relies heavily on proteins. When your body is exposed to potentially harmful substances, such as bacteria or a virus, your immune system sends out proteins called antibodies.These antibodies seek out and attack the virus or bacterium in an attempt to neutralize it and prevent it from multiplying and causing illness.rotein is considered a macronutrient, which means that your body needs it in large amounts every day to function properly.

Proteins vary in structure as well as function. They are constructed from a set of 20 amino acids and have distinct three-dimensional shapes.
