Question

Draw three-dimensional representation of the following amino acids:

(a) L-alanine

(b) L-Leucine

(c) D-serine

(d) D-glutamine

Short answer

(a), (b), (c) and (d) The diagrams are drawn below

Step-by-step solution

3D representation of organic compounds: 

Solid wedge:The bond that protrudes out of the plane of paper towards the viewer.

Dashed wedge: The bond that project away from the viewer or into the plane of the paper.

The bond in the plane of the paper is represented by a line.

Step 2(a) : 3-D representation of L-alanine:

L-Alanine

Step 3(b): 3-D representation of L-Leucine:

L-Leucine

Step 4(c): 3-D representation of D-Serine:

D-Serine

Step 5(d): 3-D representation of D-Glutamine:

D-Glutamine
