Nutrient Key Information
Nutrient Name:	生物素 Biotin (维生素 B7)
Nutrient Category:	Vitamins and Other Components
Measuring Unit:	µg
Nutrient Summary:	生物素Biotin是一种维生素B（维生素 B₇）。它帮助身体将食物中的碳水化合物、脂肪和蛋白质转化为能量。
Nutrient Function:	生物素在依赖于碳酸氢盐的羧化反应中作为辅酶发挥作用以从食物中产生能量。 • 蛋白质、碳水化合物和脂肪代谢 • 参与糖异生、脂肪酸合成以及某些脂肪酸和氨基酸的分解 • 能量存储（大多数生物素储存于肝脏中） • 在组蛋白修饰、基因调控和细胞信号传导中起关键作用。备注： 1. 含有生物素的膳食补充剂宣称生物素能改善头发、皮肤和指甲的健康，但是，需要更多的科学研究来支持这些说法。 2. 作为一种B维生素，生物素 Biotin 是水溶性维生素。水溶性维生素直接进入血液中，在体内不易储存。

备注：
1. 食物的生物素含量通常没有记录，因此在食物营养查询结果中您可能看不到的生物素含量值。
2. 生物素存在于许多天然食物中，但其浓度各不相同。
3. 生蛋清含有一种与生物素结合的蛋白质，它阻止生物素在小肠中被吸收。

Additional Nutrient Information
Nutrient Summary	生物素Biotin是一种维生素B（维生素 B₇）。它帮助身体将食物中的碳水化合物、脂肪和蛋白质转化为能量。
Deficiency Health Effects	生物素缺乏症在美国非常罕见。生物素缺乏可能导致： • 眼睛、鼻子和嘴巴周围出现红色鳞状皮疹 • 头发稀疏和体毛脱落 • 结膜炎 • 中枢神经系统疾病，例如抑郁、嗜睡、幻觉、以及手、臂、腿或脚的麻木。
Effects if Above Upper Limit	目前没有足够的有关过量食用生物素的不利影响数据，所以上限还没有确定。非常高的生物素摄入量可能会干扰使用“生物素-链霉亲和素”技术的诊断测试，例如测量甲状腺激素。它可能会产生错误的正常或异常结果。
