2022年6月1日 · Folate (also known as Vitamin B9) and vitamin B12 (cobalamin) are essential water-soluble compounds that are part of the one-carbon metabolism cycle. They play an essential role in DNA production, amino acid homeostasis, antioxidant activities and epigenetic regulation (Lyon et al., 2020).

维生素B1主要功能是在能量代谢和神经细胞中发挥作用，缺乏会导致脚气病（出现水肿或者肌肉萎缩）、心脏扩大衰竭、肌无力、疼痛、冷漠、短时记忆差、糊涂烦躁、行走困难、瘫痪、厌食和体重下降。 摄入过量的症状现不明显。 推荐摄入量：男性1.2毫克每天、女性1.1毫克每天。 主要食物来源：180克纯瘦猪排骨、80克炒瓜子、7个土豆，以上任一种都可以满足人体对维生素B1一天的需求量，另外全谷物、豆类、肝和植物种子也富含维生素B2。 PS:维生素B1的消化吸收会 …

2024年3月29日 · Vitamins B9 and B12 are involved in the metabolic pathway that converts homocysteine into methionine, a benign amino acid. By keeping homocysteine levels in check, the combined intake of B9 and B12 plays a vital role in cardiovascular health, reducing the risk of heart attack, stroke, and peripheral vascular disease [3] .

2022年4月21日 · 而人體代謝同半胱胺酸的作用需要維生素B6、B9（葉酸）及B12，所以日常生活補充足夠的B6、B9、B12能預防心血管疾病及腦血管疾病。 改善貧血：B6、B9、B12.

2024年8月20日 · Vitamins B12 (cobalamin) and B9 (folate) are both coenzymes necessary for DNA synthesis, and their deficiencies are primary causes of megaloblastic anemia (Figure 1). Deficiencies in B12 and/or folate can have profound clinical consequences, with substantial morbidity and potentially long-lasting sequelae.

2024年1月8日 · Water soluble means they aren’t stored by your body, so you need to eat them daily for the best effects. (One exception to this is vitamin B12. Excess B12 is stored in your liver.) Coenzyme means they work to power enzymes. Enzymes are proteins that help speed up chemical reactions in your body. But they can’t work on their own.

Vitamins B9 (folate) and B12 are essential water-soluble vitamins that play a crucial role in the maintenance of one-carbon metabolism: a set of interconnected biochemical pathways driven by folate and methionine to generate methyl groups for use in DNA synthesis, amino acid homeostasis, antioxidant generation, and epigenetic regulation.

2016年8月24日 · For instance, B12 and B9 (folate) together help to make red blood cells. B12, B6, and B9 team up to control blood levels of the amino acid homocysteine, high levels of which have been associated with possible heart disease. B12 deficiency: Who is at risk? Most healthy adults get sufficient B12 from their regular diet.

2023年6月1日 · 维生素b9---叶酸. 生理功能. 叶酸的生理功能是作为单碳转移酶系的辅酶， 参与dna和rna合成和氨基酸代谢，以促进正常细胞分裂、红细胞生成和高半胱氨酸转化为蛋氨酸。 在快速生长的时期，如 胎儿发育期，叶酸是至关重要的。 缺乏症状. 叶酸缺乏会导致严重后果

2021年12月28日 · Vitamins B9 and B12 are the only water-soluble vitamins stored in our liver. All other water-soluble vitamins are excreted in the urine. Vitamin B 9: 3-4 months. Vitamin B 12: 3-4 years. The dose depends on age, pregnancy, and breastfeeding.
