Although what ISAF will leave behind is better than what was there in 2001, Afghanistan remains a battered land.
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. When you eat protein, your body breaks it down into amino acids that are used for several purposes.
Proteins are molecules made of amino acids. They are coded for by our genes and form the basis of living tissues. They also play a central role in biological processes.For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.ideo: Role of proteins in human development. Each protein has a specific role in our body. However, scientists have discovered that some proteins perform more than 1 role. For example, Dr Julia Horsfield leads the Chromosome Structure and Development Group at the University of Otago.
