Esterified Fatty Acid Analysis

Fatty acids (FAs) play an important role in the human body and are used as biomarkers in the early stages of various pathological development. CD BioGlyco has been committed to FAs analysis and research for many years and has been greatly recognized internationally. We provide customers with analysis services of esterified fatty acids (EFAs) in diverse samples by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detector (GC-FID).

Background

Fat is composed of a complex mixture of FAs. FAs are essential nutrients for the human body and an important component of tissue cells. FAs include saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs). SFAs affect blood lipids. MUFAs have the effects of lowering blood sugar, regulating blood lipids, and lowering cholesterol. PUFAs have important regulatory effects on the structure and physiological functions of various tissues in the body.

In human blood, FAs exist in various compounds in a combined form, collectively referred to as lipids. In addition to EFAs, there are also non-esterified fatty acids (NEFAs) or free fatty acids (FFAs) in the blood. EFAs and NEFAs are metabolized through different pathways and play different roles. Synthesis of NEFAs produces EFAs and decomposition of EFAs produces NEFAs. FAs are used as biomarkers in the early stages of various pathological development. When studying the role and metabolism of FAs in the body, it is necessary to quantitatively analyze the free and bound forms of FAs present in biological samples.
