Keratin, collagen, elastin and fibronectin are some examples of fibrous proteins. Fibrous proteins contain repeating sets of amino acid residues that make them both strong and elongated. They are insoluble and carry out important tasks in the body.

Difference Between Globular and Fibrous Proteins. The word protein is derived from the Greek word ‘proteos’ meaning first. The name indicates that they are very essential for the growth and maintenance of the body. They occur in the protoplasm of the living cells. Proteins fulfill a wide range of functions such as mechanical movements, transporting cellular necessities such as oxygen, metal etc. Based on solubility they are classified into two groups: Fibrous and Globular proteins.

Collagen is the most abundant fibrous protein in the human body. A typical collagen molecule contains three polypeptide chains joined together by hydrogen bonds in the chain. Collagen is mostly found in the bones, skin and connective tissues within the body.

They are asymmetrical in shape and are a peptide chain held together by very strong intermolecular hydrogen bonds. Insulin and egg albumin are two examples of globular proteins, while keratin, fibroin and collagen are some examples of fibrous proteins. The word protein is derived from the Greek word proteos, meaning first.

Globular proteins are spherical, elliptical or oval in shape and soluble in water, acids and bases, while fibrous proteins are not soluble, except in strong concentrations of acid and alkali. Fibrous proteins are one of three types of scleroprotein that make up connective tissue, bone matrices, tendons and muscle fiber.

An easy way to differentiate the two is to picture their respective names; globular being glob-like and circular in structure, held together by a weak intermolecular hydrogen bond, whereas fibrous proteins look more similar to fibers of an elongated thread.

Globular structure and solubility[edit] The term globular protein is quite old (dating probably from the 19th century) and is now somewhat archaic given the hundreds of thousands of proteins and more elegant and descriptive structural motif vocabulary.

3-dimensional structure of hemoglobin, a globular protein. Globular proteins or spheroproteins are spherical (globe-like) proteins and are one of the common protein types (the others being fibrous, disordered and membrane proteins). Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins. There are multiple fold classes of globular proteins, since there are many different architectures that can fold into a roughly spherical shape.

They are long, elongated, thread-like and asymmetric in shape. They are spherical, oval or elliptical in shape. 2. The peptide chains are held together by strong intermolecular hydrogen bonds. The peptide chains are held together by relatively weak intramolecular hydrogen bonds. 3.

what are globular and fibrous proteins
Globular proteins are spherical, elliptical or oval in shape and soluble in water, acids and bases, while fibrous proteins are not soluble, except in strong concentrations of acid and alkali.
