General description

Hexanoic acid is a resistance priming inducer that protects tomato plants from Botrytis cinerea.

Application

Hexanoic acid can be used:
  • To prepare polyethylene glycol derived nanomicelles as a non-viral gene carrier.
  • As a starting material to synthesize an amino acid L-norleucine.
  • As a reactant to prepare 4-methoxy phenyl hexyl ketone through Friedel−Crafts acylation of anisole using Hβ zeolite-based catalyst.
  • As a template in the preparation of highly conducting thin polypyrrole coated alumina composite particles.

Treatment with the resistance priming inducer hexanoic acid (Hx) protects tomato plants from Botrytis cinerea by activating defence responses. To investigate the molecular mechanisms underlying hexanoic acid-induced resistance (Hx-IR), we compared the expression profiles of three different conditions: Botrytis-infected plants...
Protocols
In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
