Description générale
Linoleic acid is an octadecadienoic acid and has two double bonds at carbon 9 and 12. It is an essential polyunsaturated fatty acid (PUFA) abundantly found in plant oils.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here
Application
This analytical standard can also be used as follows:
- Multi-residue analysis of oleic acid and other related fatty acids using a derivatization-free method based on gas chromatography-flame ionization detection (GC-FID)
- Separation and quantification of palmitic, oleic, linoleic, and linolenic acids from 186 samples of sea buckthorn seed oil using near-infrared spectroscopy (NIR) in combination with four different combinations of multivariate calibration methods— partial least squares (PLS), PLS-uninformative variables elimination (UVE), PLS- competitive adaptive reweighted sampling (CARS), and multiple linear regression (MLR)-UVE
- Separation and determination of fatty acids by gas chromatography (GC) and amino acids by ultra-fast liquid chromatography-ultraviolet (UFLC-UV) detection from goldband goatfish harvested during different seasons
- Ultra-performance liquid chromatography-mass spectrometry (UHPLC) method-based separation, identification, and determination of eight saturated and unsaturated fatty acids in eight different commercial samples of olive oil without any prior sample treatment
- Magnetic solid-phase extraction of free fatty acids from edible oil samples using monodisperse magnetic single-crystal ferrite (Fe3O4) nanoparticles for their determination by gas chromatography-flame ionization detection (GC-FID)
Actions biochimiques/physiologiques
L'acide linoléique augmente la prolifération cellulaire ainsi que l'expression des gènes du récepteur PPARα et de ses gènes cibles tels que l'acyl-CoA oxydase dans les lignées primaires d'hépatocytes de canard.
