一般描述
二十碳五烯酸是通过亚麻酸合成的多不饱和脂肪酸(PUFA)。它分布于细胞膜的磷脂双分子层、大脑突触膜和视网膜中。它主要来源于鱼油、海草、浮游植物和亚麻荠。作为ω-3脂肪酸,它具有顺反构象。
应用
顺式-5,8,11,14,17-二十碳五烯酸已用于:
- 检测其对肝细胞脂肪变性的药理作用
- 作为拉曼光谱法的分析标准品表征人乳腺癌样本
- 小鼠胚胎成纤维细胞的脂质过氧化分析和细胞活性检测中的细胞预处理
生化/生理作用
5-脂氧合酶抑制剂;减少凝血噁烷 A2 生成。
二十碳五烯酸(EPA)是健康生活的必需脂肪酸,并且可缓解肥胖症。它可通过调节极低密度脂蛋白(VLDL)水平来降低甘油三酯水平。
