Long-chain Fatty Acid Analysis

Long-chain Fatty Acid Analysis

CD BioGlyco is a leader in the field of Fatty Acid Analysis. Our scientists have been committed to the research of long-chain fatty acids (LCFAs), have accumulated rich experience, and achieved many results. We provide customers with analysis services of a variety of LCFAs.

Function of LCFAs

FAs are a class of carboxylic acid compounds, which are the main components of neutral fats, phospholipids, and glycolipids. According to different carbon chain lengths, FAs are classified into short-chain fatty acids (SCFAs), medium-chain fatty acids (MCFAs), LCFAs, and very long-chain fatty acids(VLCFAs). They convert each other in the process of life and play an important role in regulating various physiological and biological functions in the organism.

LCFAs refer to FAs with 14 to 24 carbon atoms, such as palmitic acid, stearic acid, oleic acid, and α-linolenic acid. They are found in most fats and oils, including olive oil, soybean oil, fish, nuts, avocado, and meat. LCFAs have two main functions in animals: 1) As a component of phospholipids and other complex lipids, they are an important structural component of cell membranes; 2) As a part of triacylglycerol, it is an important energy source for many tissues, and it also plays an important role in activating protein kinase C (PKC) and nuclear transcription factor pathways.

LCFAs play a role in cells through passive diffusion or carrier-mediated transport across the plasma membrane. The uptake of LCFAs by adipocytes plays an important role in maintaining lipid homeostasis. Adipocytes produce lipoprotein lipase, which acts on lipoprotein particles to produce LCFAs. After passing through endothelial cells, LCFAs bound to mesenchymal albumin interact with adipocytes to participate in a variety of metabolic processes.

Our Services

LCFAs play a huge role in people's daily life, so scientists have been committed to the research of LCFAs. CD BioGlyco quantifies LCFAs by gas chromatography-mass spectrometry (GC-MS). Our analysis process is as follows:
