WebHemoglobin is a protein; a molecule contains four polypeptide chains (a tetramer), each chain consisting of more than 140 amino acids. To each chain is attached a chemical structure known as a heme group. Heme is composed of a ringlike organic compound known as a porphyrin, to which an iron atom is attached. WebIt actually is a porphyrin structure. And if you watch the video on chlorophyll, you'd remember a porphyrin structure, but at the very center of it, in chlorophyll, we had a …
