| Common Name | 8-Methylnonenoate |

| Description | 8-methyl-nonenoic acid is a fatty acid derivative from leucine/valine pathway.8-methyl-nonenoic acid plays a crucial role in determining the efficacy of capsaicin levels.It was evident that significantly high capsaicin was produced when 8-methyl-nonenoic acid was supplied individually and in combination with vanillylamine. This suggests that 8-methyl-nonenoic acid is very close in pathway, leading to capsaicin biosynthesis, and although vanillylamine is present in abundance, the quantity of 8-methyl-nonenoic acid determines the pungency in placental tissues of Capsicum. |
