产品描述

General description

Biotin is readily available in several foods, like whole grains, nuts, legumes, unpolished rice and egg yolk. The normal gut flora also produces this vitamin.[7]

Application

生物素已被用于检测展示亲和素的噬菌体的功能。[3]该产品还被用于标记猪抗兔 IgG 抗体和过氧化物酶。[4]

Biochem/physiol Actions

Biotin acts as an important cofactor for carboxylase enzymes in various metabolic pathways. Biotin favors keratin synthesis and hence is used as a supplement for hair and nail growth. Deficiency of biotin shows several symptoms such as alopecia, conjunctivitis, seborrheic dermatitis, depression, lethargy, hypotonia and seizures.[7]

生物素也称为维生素 H 或维生素 B7,是一种水溶性 B 族维生素,可诱导大鼠肝脏、肾脏、结肠、小脑和心脏中鸟苷酸环化酶活性增加 2-3 倍。[5]还能刺激精子活力,延长冷冻保存的人体精子的存活时间。[6]
