MICROANATOMY

Detailed explanation-1: -Albumin helps maintain the colloid osmotic pressure of the blood. It is the smallest in size among the plasma proteins but makes up the largest percentage. The colloid osmotic pressure of the blood is important in maintaining a balance between the water inside the blood and that in the tissue fluid, around the cells.

Detailed explanation-2: -Human albumin is a small globular protein with a molecular weight of 66.5 kilodaltons (kDa). It consists of 585 amino acids which are organized into three repeated homologous domains and are made up of two separate sub-domains, A and B.

Detailed explanation-3: -Serum albumin is the largest protein component of human blood (50–60%), and is an important factor in the regulation of plasma volume and tissue fluid balance.

Detailed explanation-4: -Albumin is known as a multifunctional plasma protein. It is the main regulator of plasma oncotic pressure.

Detailed explanation-5: -The normal range is 3.5 to 5.5 g/dL or 35-55 g/liter. This range may vary slightly in different laboratories. Albumin composes 50%-60% of blood plasma proteins.
