In 1967, John Shepherd-Barron invented and installed an ATM in a Barclays Bank in London. Don Wetzel invented an American made ATM in 1968. However, it wasn't until the mid to late 1980s that ATMs became part of mainstream banking.
Hemoglobin is a globular protein made up of four subunits, each of which contains a polypeptide chain called globin and a heme group. Each hemoglobin molecule is composed of two types of globins organized into four subunits.The two sets of globin chains have minute differences in the sequence and types of amino acids comprising them. This amino acid sequence of a protein is called the primary structure.ach hemoglobin molecule is composed of two types of globins organized into four subunits.

Hemoglobin is present in red blood cells and is an essential chemical which carries oxygen from lungs to other parts of the body. It is metalloprotein having quarternary structure which contains iron and performs the important function of transporting oxygen via RBCs in blood in mammals as well as other animals.he name hemoglobin is made from the blend of heme and globin. Globin is the globular protein in which heme-an iron atom is embedded which is the main chemical binding oxygen. The common type of hemoglobin consists of four subunits: 1  Two alpha (Î±) subunits or globins.
