| Application: | This analytical standard can also be used as follows: • Simultaneous identification and quantification of fatty acids from blood plasma samples after their methyl derivatization by large-volume injection (LVI) gas chromatography combined with vacuum ultraviolet spectroscopy (GC-VUV) • Determination of the fatty acid composition of sunflower seed oils extracted from 93 different sunflower varieties by near-infrared reflectance spectroscopy (NIRS) combined with modified partial least squares (MPLS) and partial least squares (PLS) regression methods • 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 • 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) • 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 • Development of a liquid chromatography-mass spectrometry (LC-MS) method to measure seven fatty acid esters of hydroxy fatty acids (FAHFAs), four fatty acids, and four cardiovascular-related biomarkers in plasma samples of 57 healthy individuals |
| General description: | Oleic acid is a long-chain unsaturated fatty acid, having a double bond between C9 and C10 with a cis configuration. It is the most found fatty acid and occurs in most oils and fats to some extent. |
