应用
Arachidic acid is used in the manufacture of pharmaceuticals, soaps, cosmetics, and food packaging because of its surfactant-like properties. Arachidic acid is a saturated fatty acid with a 20 carbon chain. Diets rich in saturated fats like arachidic acid are associated with increased levels of serum low density lipoproteins.

产品说明

应用

花生四烯酸已作为脂肪酸标准品用于 优化灵敏的高效液相色谱(HPLC)法，以对脂肪酸(FA)进行分析，定量测定细胞脂质提取物中的多不饱和FA(PUFA)。

包装

500 mg in poly bottle
1, 5, 10, 25 g in poly bottle

生化/生理作用

花生酸是一种 20 碳链的饱和脂肪酸。花生酸天然存在于鱼和植物油中。富含饱和脂肪(如花生酸)的饮食与血清低密度脂蛋白水平升高相关。

Ion Mobility: TWCCSN2 value of 187.2 Å2 [M-H]-

The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.

TWCCS measurements are expected to be within 2% of this reference value.
