Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

A 3d structure of a biomolecule not only depends upon the covalent bond that it forms but also on the arrangement of its constitutent atoms in three dimensional space i. e. on the stereochemistry. All biomolecules are carbon containing compounds which exist as stereoisomers. Stereoisomers are chemical compounds with same chemical formula but different arrangement of atoms in 3d space. Van der Waals radius of an atom depicts the volume of space from which other molecules are excluded. The radius of an atom is proportional to it's van der Waals radius. It means that how different atoms of a biomolecule will be arranged in 3d space depends upon van der Waals radius which simply implies that van der Waals radius play an important role in deciding 3d structure of a biomolecule.
Thank you madam
