BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A hemoglobin molecule is made up of four polypeptide chains, two alpha chains of 141 amino acid residues each and two beta chains of 146 amino acid residues each.

Detailed explanation-2: -Hemoglobin is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom.

Detailed explanation-3: -The hemoglobin molecule is made up of four polypeptide chains (Alpha 1, Beta 1, Alpha 2, Beta 2), noncovalently bound to each other. There are four heme-iron complexes. Each chain holds a heme group containing one Fe++ atom. The heme-iron complexes are colored red because they give hemoglobin its red color.

Detailed explanation-4: -Normal hemoglobin consists of four globin chains, each holding a heme molecule that contains iron. Globin is a complex protein containing a precise sequence of amino acids that allows it to fold into a complex conformational pattern.

Detailed explanation-5: -Hemoglobin is a complex protein which has a quaternary structure and contains iron. There are four subunits in the hemoglobin molecule-two alpha subunits and two beta subunits.
