代谢
醋酸能被胃肠道和肺部很好地吸收。醋酸根在氧化代谢或合成代谢中被完全利用。同位素实验表明,醋酸根用于形成肝糖原、碳水化合物中间体、磷脂和脂肪酸,以及胆固醇和类固醇的合成。此外,它还参与胺的乙酰化,并且可以通过转氨作用转化为丙氨酸,进而被纳入血浆、肝脏、肾脏、肠道粘膜、肌肉和大脑的蛋白质中。/醋酸/
Acetic acid is absorbed readily from the gastrointestinal tract and from the lungs. ... Acetate is completely utilized in oxidative metabolism or in anabolic syntheses. Isotope experiments have shown acetate to be utilized in the formation of glycogen, carbohydrate intermediates, phospholipids, and fatty acids, as well as in cholesterol and steroid synthesis. In addition, it participates in the acetylation of amines and may be converted to alanine by transamination and /from there/ incorporated into proteins of plasma, liver, kidney, gut mucosa, muscle, and brain. /Acetic acid/
