Trimethylacetaldehyde
Based on 1 Customer Validation
Trimethylacetaldehyde (Pivalic aldehyde; Pivalaldehyde) is an inhibitor of E. coli betaine aldehyde dehydrogenase (ALDH) with a Ki of 4.5 mM. Trimethylacetaldehyde serves as a substrate for Drosophila melanogaster alcohol dehydrogenase (AdhS), undergoing oxidation and disproportionation reactions with the release of NADH, and also forms an inactive binary enzyme-aldehyde complex via a compulsory ordered reaction mechanism.

Biological Activity
Description
In Vitro
Trimethylacetaldehyde (100 mM) competitively inhibits purified betaine aldehyde dehydrogenase from Escherichia coli MC4100 (pFF423), with an apparent inhibition constant of 4.5 mM, and reduces the enzyme activity to 11% of that in the control group at a concentration of 100 mM[2].
