Document Summary
Proteins are large, complex molecules with many functions. Contain carbon (c), hydrogen (h), oxygen (o) and nitrogen (n) grouped together in love strands of amino acids (aa) Our body contains thousands of different proteins: in bones (osteocalcin), blood (hemoglobin), hormones (testosterone), muscles (myosin), organs (lipoproteins) They are made out of amino acids: ex. This is how: what makes the amino acids different from one another is the composition of the side the body makes new aa chain, essential important, not all have to be consumed. When 2 amino acids bond, the amino group of one binds to the acid group of another. Hemoglobin made of 4 polypeptide chains, folded in a way to give hemoglobin a distinctive shapeo is the iron containing, oxygen-transporting protein found in red blood cells. The shape of a protein determines the function of a protein. Change in the shape of the polypeptide will affect the shape of the red blood cell: ex.
