ChEBI: Geranic acid is a polyunsaturated fatty acid that is octa-2,6-dienoic acid bearing two methyl substituents at positions 3 and 7 (the 2E-isomer). It has a role as a pheromone, an EC 1.14.18.1 (tyrosinase) inhibitor, a plant metabolite, an antifungal agent and a melanin synthesis inhibitor. It is a polyunsaturated fatty acid, a methyl-branched fatty acid, a monoterpenoid and an alpha,beta-unsaturated monocarboxylic acid. It is a conjugate acid of a geranate.
Geranic acidacid is produced
1) from 2-Methylhepten-2-one-6 with Iodoor Bromoacetic ester and a Zinc type catalyst.
2) by oxidation of Citral.
Medium strength odor, green type; recommend smelling in a 10.0% solution or less.
Sweet, woody, leafy, fruity body with some mouthfeel effects at 20 ppm.
Geranic acid is a monoterpenemainly used in flavor, fragrance, cosmetics and agro-industries. In vitro studies show that geranic acid exhibits strong inhibitory activity against Fusarium graminearum and Colletotrichum graminicola, the two main fungal pathogens of maize. It may be responsible for the potent tyrosinase inhibitory activity of lemongrass (Cymbopogon citratus).
Odor (neat): sweet, floral green, geranium leaf-like, woody with a citrus orange body nuance.
