關於維生素E菸酸酯
Vitamin E Nicotinate can relax peripheral blood vessels, increase blood flow, reduce capillary permeability, and inhibit the synthesis of cholesterol.維生素E菸酸酯可放鬆周圍血管，增加血流量，降低毛細血管通透性並抑制膽固醇的合成。 Large doses can lower serum cholesterol and diacylglycerol concentrations.大劑量可以降低血清膽固醇和二酰基甘油的濃度。 50% to 80% Vitamin E Nicotinate is absorbed in the intestines.腸內吸收了13％至4％的維生素E菸酸酯。 Absorption requires the presence of bile salts and dietary fat, as well as normal pancreatic function.吸收需要膽汁鹽和膳食脂肪的存在，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.它與血液中的XNUMX種脂蛋白結合，並存儲在全身組織中，尤其是在脂肪組織中。 The storage capacity is available for XNUMX years.存儲容量為XNUMX年。 After metabolism in the liver, excretion is done through the bile and kidney.肝臟中新陳代謝後，通過膽汁和腎臟排泄。 Niacin is absorbed in the gastrointestinal tract.菸酸在胃腸道中吸收。 In the therapeutic amount of niacin, only a small amount of the original form and metabolites are excreted from the urine.在治療量的菸酸中，只有少量的原始形式和代謝物從尿中排出。 When the dosage exceeds the need, most of it is excreted through the kidney.當劑量超過需要時，大部分會通過腎臟排泄。 In food, tryptophan is converted to niacin by intestinal bacteria, and niacin has peripheral vasodilating effects.在食品中，色氨酸被腸細菌轉化為菸酸，菸酸具有外周血管舒張作用。
