棕榈酸的代谢及生理功能与在三酰甘油上结合的位置有关。在代谢过程中通常是1,3位的脂肪酸首先被胃酶和胰酯酶水解下来形成2-棕榈酸单甘酯和游离脂肪酸,2-棕榈酸单甘酯可以直接被人体吸收。母乳脂肪酸的20%～25%是棕榈酸,而且70%的棕榈酸在Sn-2位置上被脂化;相反,存于植物油和非牛奶脂肪内的棕榈酸主要在Sn-1和Sn-3的位置上脂化,而结合在1,3位置上的棕榈酸不易被机体吸收,容易形成不溶性的皂化钙随粪便排出体外,导致能量和钙的流失。

Spin-orbit torque （SOT）,as a promising writing method for magnetic random-access memory （MRAM）,has garnered widespread interest for over a decade [1].Heavy metals,such as β-W,have been broadly adopted as spin current sources,but suffer from phase change at a limited thickness,resulting in a dramatic reduction of the charge-tospin conversion efficiency θSH[2].The thickness limitation leads to stringent etching conditions and large distribution among devices,posing challenges for simultaneously satisfying SOT efficiency,etching-stop margins,and back-end-ofline （BEOL） compatibility.
