Globular protein

Globular proteins or spheroproteins are one of the common protein types (the others being fibrous, disordered and membrane proteins). The name 'globular' is derived from their rounded, spherical shape, which is determined by their tertiary structure.

Structure

Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins. There are multiple types of globular proteins, each differing in their structure and functions. They are typically compact, soluble, and spherical in shape. They are also involved in various functions, including transport, enzymes, and antibodies.

Function

Globular proteins perform various functions in the body. They can act as enzymes, performing biochemical reactions including metabolism, DNA replication, DNA repair, and RNA synthesis. They can also act as transport proteins, binding small molecules or bio-macromolecules and carrying them throughout the body. Some globular proteins are involved in cell signaling, immune response, and maintaining the cell structure.

Examples

Some examples of globular proteins include hemoglobin, insulin, and immunoglobulins. Hemoglobin is a globular protein that transports oxygen from the lungs to the rest of the body. Insulin is a globular protein that regulates the metabolism of carbohydrates and fats in the body. Immunoglobulins are globular proteins that function as antibodies in the immune response.
