不饱和脂肪酸是人体的必需脂肪酸。根据C = C双键的数量，不饱和脂肪酸分为单不饱和脂肪酸（0-9系列）和多不饱和脂肪酸。根据C = C双键的位置和功能，将多不饱和脂肪酸分为ω-6系和ω-3系列。
Unsaturated fatty acids have a variety of physiological functions, such as maintaining the relative fluidity of cell membranes, reducing high blood pressure, preventing vascular sclerosis, reducing high blood pressure and cholesterol. Supplementing EPA and DHA can enhance the body's immunity. At the same time, DHA is an important part of the retina, as well as an indispensable material basis for the formation, development and movement of brain cells. a-linolenic acid can improve the brain development and cranial nerve function of the fetus, and can enhance the vision of the fetus.
我过多或不足的不饱和脂肪酸n the diet may have an impact on human health. Therefore, it is necessary to detect the content of unsaturated fatty acids. Creative Proteomics has GC-MS and LC-MS detection platforms, which can achieve efficient and accurate determination of unsaturated fatty acids.
Absolute quantification: Use external standard method to quantify, and use internal standard for correction, qualitative and quantitative is more accurate.
High sensitivity: we use liquid chromatography coupled with triple quadrupole mass spectrometers for unsaturated fatty acids analysis service (Triple Quad™ 6500 LC-MS/MS System).
