General description

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)

Biochem/physiol Actions

Linoleic acid increases cell proliferation and gene expression of PPARα and its target genes such as acyl-CoA oxidase in primary duck hepatocytes .
