一般說明

硫胺素或维生素B1带正电荷,是所有组织的基本成分。它在骨骼肌、肝脏、肾脏、心脏和大脑中含量较高。[1]硫胺素由一个嘧啶环组成,通过亚甲基桥连接到一个噻唑环。 [2]

應用

盐酸硫胺素已被用作以下物质的组分:
  • 维生素浓缩原液,用于制备培养火山富盐菌的Hv-Ca培养基[3]
  • 三乙酸磷酸盐(TAP)培养基,用于培养雪衣藻[4]
  • 改良Bold 3N培养基,用于培养小球藻[5]

生化/生理作用

硫胺素通过硫胺素二磷酸激酶进入细胞膜后转化为二磷酸硫胺素。[1]二磷酸硫胺素是一种活性辅因子,对于许多酶的机制至关重要,这些酶参与柠檬酸循环、糖酵解途径、支链氨基酸降解和磷酸戊糖通路。[6]硫胺素参与将食物转化为能量的过程,供中枢和外周神经系统运作使用。该维生素的低水平与谵妄、Wernicke脑病和Wernicke-Korsakoff综合征有关。[7]盐酸硫胺素是培养细胞能量代谢和氨基酸合成所必需的。它存在于许多经典和无血清配方中。

Antibiotic-tolerant persisters are often implicated in treatment failure of chronic and relapsing bacterial infections, but the underlying molecular mechanisms have remained elusive. Controversies revolve around the relative contribution of specific genetic switches called toxin-antitoxin (TA) modules and global modulation of
