Question

Give an example of fibrous and globular protein

Answer 1

Hint: The globular protein is defined as the protein which is made up by the chain of amino acids or the polypeptide chain. The globular protein is joined with the peptides bonds. The fibrous proteins act as the structural protein and have elongated strands like structures.

Complete step-by-step answer:The fibrous proteins are considered as the major components of the connective tissue and blood vessels walls. They tend to contain the elongated chain of polypeptides which run parallel to one another and they are stabilized by the cross linkages. They help in providing support and also aid in the biomechanics. The common example of fibrous protein is collagen. It constitutes the\[30%\]of the total protein which is present in the body. The collagen is present in the form of triple helix which tends to come from the high abundance of glycine, hydroxyproline and proline. The fibrous protein is a thread like which can be occurring in singly or in groups. These proteins are tough , structural and non enzymatic.
The globular protein can act as enzymes by helping in catalyzation of the organic reactions. They also act as messengers, hormones, transporters and amino acid stokes. The example of globular protein is haemoglobin which is considered as the member of the globin protein family. The other globulins are alpha beta and gamma ( IgA, IgD, IgE, IgE and IgM.) The signal transduction proteins and enzymes with their metabolic functions are globular in shape. Haemoglobin is the main protein which is present in red blood cells.

Note: The globular proteins tend to be soluble and compact and considered as the integral part of biological processes in living organisms. They function as the enzymes, hormones and proteins. The collagen is fibrous protein which is present in skin, muscles and bones which helps in the regulation of blood sugar.
