Concept explainers
Interpretation:
The configuration of the β-hydroxyacyl CoA formed by hydration during a turn of the β-oxidation pathway has to be determined.
Concept introduction:
Theβ-oxidation pathway is defined as a repetitive series of four biochemical reactions in which acyl CoA is degraded to acetyl CoA by the removal of two carbon atoms at a time. NADH and FADH2 are also produced in this pathway.
The configuration is defined as the spatial arrangement of atoms or groups in a molecule. The stereoisomers have the same molecular formula but a different arrangement of atoms in the three-dimensional space. The D and L notation describes the configurational stereochemistry of molecules.
In the D isomer, the hydroxy (-OH) group present on the farthest chiral centre from the carbonyl is present on the right side while in the L isomer, the hydroxy group present on the farthest chiral centre from the carbonyl is present on the left side.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.
