yeah it is made of amino acids but your body cant use it in the form you eat it ie meat etc - it has to break ot back down into amono acids and then synthesize it the metabolism back into a structure that your body requires, then it sends it to the needed parts of your body. You don't end up with a bit of chicken in your bicep but the amino acids used to create tthe new cels for your bicep may have originally come from a piece of digested chicken. Thats where vits, mins and enzymes come in.
