how are proteins classified on the basis of molecular shape
Answers
Answer:
On the basis of their molecular shapes proteins are classified as
(1) Fibrous proteins: The proteins in which the polypeptide chains lie parallel (side by side) to form fibre-like structure, are called fibrous proteins. The polypeptide chains held together by hydrogen bonds. These proteins are insoluble in The fibrous proteins water. are tough and insoluble in water, and dilute acids or bases.
(2) Globular Example: myocin (in muscles), keratin (in hair, nails, skin). fibroin (in silk). collagen (in tendons), etc. The proteins have spherical shape. This shape results from coiling around of the polypeptide chain of protein, proteins: and have intramolecular hydrogen bonding are called globular proteins. They are soluble in water and dilute acids or bases. Example : Haemoglobin (in blood), albumin (in eggs), insulin (in pancreas), etc.
Answer:
On the basis of molecular shape,proteins are classified into two types—fibrous proteins and globular proteins. ... They are folded to form a sphericalshape, have intramolecular hydrogen bonding and have weak intermolecular forces as compared to fibrousproteins.
