Protein is an essential nutrient, needed for growth and repair of tissues. For this reason, it is listed on food labels. It is actually the amino acids that proteins are made of that we need to make our own proteins. So before we can use the protein in our food we have to digestit ie break it down into amino acids. The amino acids are then absorbed into the blood and used to make new proteins. Amino acids which are present in excess are broken down in the liver into a substance called urea which we excrete in the urine. Amino acids which the body cannot make, and so must be obtained from our food, are called essential amino acids. Amino acids which the body can make are called non-essential. Proteins are sometimes classified as first class (which contain all of the amino acids which we need) and second class (which lack some essential amino acids). http://www.netfit.co.uk/nutrition/nutrition/proteins.htm http://www.nutrition.org.uk/home.asp?siteId=43§ionId=299&which=1
