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 a molecule comprised of four subunits. Each subunit contains an iron containing pigment (heme) and a protein (globulin). There are two types of subunits, alpha and beta. Each gram of hemoglobin can carry 1.34 ml of oxygen.The oxygen carrying ability of blood is directly proportional to its hemoglobin concentration.emoglobin also serves as an important pH buffer in the extracellular fluid. 1  Normal hemoglobin values are: 2  Adult: (males): 13.5 - 17 g/dl. ( 3 Females): 12 - 15 g/dl. 4  Pregnancy: 11 - 12 g/dl. 5  Newborn: 14-24 g/dl 77% of this value is fetal hemoglobin, which drops to approximately 23% of the total at 4 months of age.
