The saturated fatty acids in the sn-1 and -3 position of triacylglycerols can exhibit different metabolic patterns due to their low absorptivity. This means that dietary fats containing saturated fats primarily in sn-1 and -3 positions (e.g., cocoa butter, coconut oil, and palm oil) can have very different biological consequences than those fats in which the saturated fats are primarily in the sn-2 position (e.g., milk fat and lard). Differences in stereospecific fatty acid location should therefore be an important consideration in the design and interpretation of lipid nutrition studies and in the production of specialty food products.
三酰甘油sn-1和-3位上的饱和脂肪酸由于其低吸收率而可能呈现出不同的代谢模式。这意味着,主要在sn-1和-3位含有饱和脂肪的膳食脂肪(如可可脂、椰子油和棕榈油)与饱和脂肪主要在sn-2位的脂肪(如乳脂和猪油)相比,可能具有非常不同的生物学后果。因此,立体特异性脂肪酸位置的差异在脂质营养研究的设计和解释以及特殊食品的生产中应是一个重要的考虑因素。
