General description

Benzamide (Benzoic acid amide, BA) is an amide of benzoic acid. BA on crystallization in benzene (solvent) affords crystals suitable for X-ray analysis. Crystal structure studies suggest that its crystals are monoclinic having space group P21/c. Kinetics and mechanism of its reaction with hydrogen peroxide have been proposed.

Application

Benzamide was used to study the mechanism of photocatalytic decomposition of aqueous solution of acetic acid, acetamide and acetonitrile in the presence of semiconductors. Benzamide was used to develop a robust screening method to study biotransformations using (+)-γ-lactamase enzyme.

Biochem/physiol Actions

Inhibits poly(ADP-ribose) polymerase (PARP).

A (+)-gamma-lactamase was precipitated, cross-linked and the resulting solid crushed prior to immobilisation within a capillary column microreactor. The microreactor was subsequently used to study enzyme stability, activity, kinetics and substrate specificity. The thermophilic (+)-gamma-lactamase retained 100% of its initial
