关于维生素E烟酸酯
Vitamin E Nicotinate can relax peripheral blood vessels, increase blood flow, reduce capillary permeability, and inhibit the synthesis of cholesterol.维生素E烟酸酯可放松周围血管，增加血流量，降低毛细血管通透性并抑制胆固醇的合成。 Large doses can lower serum cholesterol and diacylglycerol concentrations.大剂量可以降低血清胆固醇和二酰基甘油的浓度。 50% to 80% Vitamin E Nicotinate is absorbed in the intestines.肠道中吸收了13％至4％的维生素E烟酸酯。 Absorption requires the presence of bile salts and dietary fat, as well as normal pancreatic function.吸收需要胆汁盐和饮食脂肪的存在，以及正常的胰腺功能。 It binds to XNUMX-lipoproteins in the blood and is stored in whole body tissues, especially in adipose tissue.它与血液中的XNUMX种脂蛋白结合，并存储在全身组织中，尤其是在脂肪组织中。 The storage capacity is available for XNUMX years.存储容量为XNUMX年。 After metabolism in the liver, excretion is done through the bile and kidney.肝脏中新陈代谢后，通过胆汁和肾脏排泄。 Niacin is absorbed in the gastrointestinal tract.烟酸在胃肠道中吸收。 In the therapeutic amount of niacin, only a small amount of the original form and metabolites are excreted from the urine.在治疗量的烟酸中，只有少量的原始形式和代谢物从尿中排出。 When the dosage exceeds the need, most of it is excreted through the kidney.当剂量超过需要时，大部分会通过肾脏排泄。 In food, tryptophan is converted to niacin by intestinal bacteria, and niacin has peripheral vasodilating effects.在食品中，色氨酸被肠细菌转化为烟酸，烟酸具有外周血管舒张作用。
