How many amino acids in myoglobin
WebHow many amino acids are there in myoglobin? Myoglobin, the oxygen carrier in muscle, is a single polypeptide chain of 153 amino acids (see also Chapters 7 and 10). The capacity of myoglobin to bind oxygen depends on the presence of heme, a nonpolypeptide prosthetic (helper) group consisting of protoporphyrin IX and a central iron atom. WebThe number of amino acids is different in both types of polypeptide chains. Each alpha chain contains 141 amino acids. ... It is also synthesized in the liver, the site of production of various other heme proteins like myoglobin and cytochromes, etc. The process of heme synthesis begins with glycine and succinyl CoA to form Aminolaevulinic acid ...
