L-Dopa _____. Question 31 options: 1) is still marketed as a racemic mixture 2) was first isolated from the leaves of the broad bean Vicia faba 3) is a chiral molecule with two chirality centers 4) has only one enantiomer that is active against Parkinson's disease 5) More than one of the statements above are true. Which structure represents the three-dimensional structure of the Fischer projection shown? and 3) and 2) and , is a naturally occurring amino acid that is chiral. What is the pair of enantiomers of alanine? Question 34 options: 1) Alanine, 4) 3) 2) Question 33 options: 1)

Explanation / Answer

31) 5

was first isolated from the leaves of the broad bean Vicia faba

has only one enantiomer that is active against Parkinson's disease.

these two are correct. and L-Dopa has only one chiral carbon is there.

33) 4

34) 2

All amion acids are L- amino acids . L-amino acids only having biological activity. so option 2 indicate L-conformation. L- configuration based on L- glyceraldehyde.(relative configuraTION)
