Question

Isocitric acid, an intermediate in the citric acid cycle of food metabolism, has the systematic name (2R,3S)-3-carboxy-2-hydroxypentane-dioic acid. Draw the structure.

Short answer

The structure of isocitric acid which has the systematic name (2R,3S)-3-carboxy-2-hydroxypentane-dioic acid is

Step-by-step solution

Definition of structure

The arrangement of chemical bonds between atoms in a molecule is defined as the structure.

Explanations

The name of isocitric acid shows that it has a five-carbon straight chain with three carboxyl groups, one at $C_1$other attached to $C_3$, a third one at $C_5$and a hydroxyl group on $C_2$.

When viewed from the group of lowest priority, the groups with first, second, and third-highest priorities are arranged in a clockwise direction on $C_2$an in an anticlockwise direction on $C_3$.

The structure of isocitric acid which has the systematic name (2R, 3S)-3-carboxy-2-hydroxypentane-dioic acid is
