当叶酸及VitB12缺乏时,则出现代谢障碍,其中,最明显的是dTMP合成受阻,导致DNA合成障碍,细胞有丝分裂减少,出现巨幼红细胞性贫血。VitB12缺乏会影响正常神经髓鞘脂质合成,出现神经症状。VitB12的吸收需内因子的参与,故萎缩性胃炎所致内因子缺乏可影响其吸收,引起恶性贫血,须注射VitB12。
Folic Acid是合成叶酸,它的通用名为蝶酰谷氨酸,是人工合成的叶酸。 Folate是活性叶酸,它的通用名是5-甲基四氢叶酸,是天然果蔬中提取的叶酸经还原、甲基化后得到的活性叶酸。 2、代谢途径不同 Folic Acid与Folate代谢步骤也有很大差别: Folic Acid合成叶酸,在肝脏处进行代谢。体内首先转化为蝶酰多聚谷氨酸,进而转化...
