Opis

General description

Palmitoleic acid (C16:1, n-7, POA) belongs to the group of natural omega-7 monounsaturated fatty acids and occurs abundantly in plant and fish oils. Cis-palmitoleic acid is known to support glucose and lipid metabolism.

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.

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)
• 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)
• Comparative evaluation of high-performance liquid chromatography (HPLC) and gas chromatography (GC) methods for the determination of cis- and trans- palmitoleic acids in fish oil samples, using a modified potassium hydroxide ester exchange method
• 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
• 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
