Question 1.

Which of the choices is a correct structure for L-valine?

An illustration shows the Fischer projections of three compounds. The first compound labeled one (Roman numeral) has a three-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group. C 2 is single bonded to an N H 2 group on the left and a hydrogen atom on the right. C 3 is an isopropyl group. The second compound labeled two (Roman numeral)has a three-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group. C 2 is single bonded to a hydrogen atom on the left and an N H 2 group on the right. C 3 is an isopropyl group. The third compound labeled three (Roman numeral) has a three-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to a hydroxyl group. C 2 is single bonded to an N H 2 group on the left and a hydrogen atom on the right. C 3 is an isobutyl group.
