Description

General description

2-Methylbutyraldehyde has been identified as one of the important flavor compounds in barley crystal malts, baked potatoes, whole milk powder (WMP).

Application

• In Staphylococcus aureus, the acyl-CoA synthetase MbcS supports branched-chain fatty acid synthesis from carboxylic acid and aldehyde precursors.: This study explores the role of the enzyme MbcS in Staphylococcus aureus, demonstrating how it utilizes 2-Methylbutyraldehyde as a precursor in the synthesis of branched-chain fatty acids, which are essential for bacterial growth and virulence (Dos Santos Ferreira et al., 2024).


• Volatile Short-Chain Aliphatic Aldehydes Act as Taste Modulators through the Orally Expressed Calcium-Sensing Receptor CaSR.: This study investigates how volatile short-chain aldehydes, including 2-Methylbutyraldehyde, modulate taste perception through the calcium-sensing receptor CaSR, providing insights into their potential applications in food and flavor industries (Kitajima et al., 2023).
