Descrizione generale

Isovaleric acid, also known as 3-methylbutanoic acid, is commonly used for ester synthesis and as a building block in organic reactions. It is a volatile organic compound present in vinegar bait and is determined by solid phase microextraction. Isovaleric acid inhibits the synthesis of saturated fatty acids. It is a favorable carbon source for cell growth. Moreover, it is a promising odor indicator.

Applicazioni

Isovaleric acid inhibits the synthesis of saturated fatty acids.
