抗坏血酸(即维生素 C)属水溶性维生素。是一种活性很强的还原性物质,参与机体的生理氧化还原过程,对机体新陈代谢起着重要作用。抗坏血酸参与细胞间质的生成,维持组织的正常功能;它对抗体形成和白细胞吞噬活性有激发作用,可增强机体的抗感染力;抗坏血酸还在防治心血管疾病和某些肿瘤方面有良好效果。同时,它与机体内某些其它营养素的代谢也存在着密切关 Ascorbic acid (ie vitamin C) is a water-soluble vitamin. Is a highly active reductive material involved in the body’s physiological redox process plays an important role in the metabolism of the body. Ascorbate participates in the formation of interstitial cells and maintains the normal function of the tissue. It stimulates the formation of antibodies and leukocyte phagocytosis and enhances the anti-infective power of the body. Ascorbic acid also has good effects in the prevention and treatment of cardiovascular diseases and certain tumors. At the same time, it is also closely related to the metabolism of certain other nutrients in the body
