Omega-6 Fatty Acid Analysis

Omega-6 Fatty Acid Analysis

Omega-6 fatty acids are essential in the human body. Omega-6 fatty acid analysis helps people to study its mechanism of action and analyze food ingredients. CD BioGlyco provides customers with omega-6 fatty acids quantitative analysis services by gas chromatography-mass spectrometer (GC-MS).

What Is Omega-6 Fatty Acid?

According to the position of the first double bond at the methyl end of the fatty acid, polyunsaturated fatty acids (PUFAs) are divided into omega-3 (ω-3) and omega-6 (ω-6) groups. Counting from the carbon on the methyl end and the double bond position at the 6th carbon is called omega-6 fatty acid. Omega-6 fatty acids are essential in the human body, but the body cannot produce them by itself and needs to be obtained from food. Food sources of omega-6 fatty acids are very rich, such as corn, soybeans, vegetable oil, fried foods, beef, lamb, etc. Omega -6 fatty acids include linoleic acid (LA) (18:2), conjugated linoleic acid (CLA) (18:2), gamma linolenic acid (GLA) (18:3), dihomo gamma linolenic acid (DGLA) (20:3), arachidonic acid (20:4), epinephrine (22:4) and eicosatetraenoic acid (ETA) (20:4).

Omega-3 fatty acids are an important component of the immune system, endocrine system, and nervous system, and play an important role in the synthesis of neurotransmitters in the nervous system. It has significant effects on tumors, endocrine system diseases, digestive system diseases, and autoimmune diseases such as Parkinson's disease, psychosis, depression, etc. In addition, it is also obvious in the prevention and treatment of cardiovascular diseases. The role of omega-3 in the prevention and treatment of human diseases: 1) Maintain the homeostasis of the human body; 2) Regulate enteral and parenteral nutrition; 3) Anti-tumor effect; 4) Anti-cardiovascular diseases.

Omega-6 fatty acids coordinate hormone levels, promote inflammation, maintain healthy nerve function, regulate menopausal premenstrual syndrome, and promote skin health. Long-term excess omega-6 fatty acids cause chronic heart attacks, thrombotic stroke, arrhythmia, arthritis, osteoporosis, inflammation, mood disorders, obesity, cancer, and other diseases. The drugs used to treat these diseases are usually effective by blocking arachidonic acid in omega-6 fatty acids.
