Question

Can you attempt building models of biomolecules using commercially available atomic models (Ball and Stick models).

Answer 1

Ball and stick models are 3-D molecular models that can be used to describe the structure of biomolecules. 

In ball and stick model, the atoms are represented as balls whereas the bonds that hold the atoms are represented by the sticks. Double and triple bonds are represented by springs that form curved connections between the balls. The size and colour of various atoms are different and are depicted by the relative size of the balls.
It is the most fundamental and common model of representing biomolecular structures. 

In the above ball and stick model of D-glucose, the oxygen atoms are represented by red balls, hydrogen atoms by blue balls, while carbon atoms are represented by grey balls.
