一般描述
偏亚硫酸氢钠（MBS，亚硫酸氢钠）是一种无机盐。它是亚硫酸的钠盐。在纺织和摄影行业，这种盐广泛用作还原剂。它通常作为防腐剂添加到各种食品和葡萄酒中。
应用
通过溶液中的自由基聚合时，亚硫酸氢钠可用于引发囊泡膜中心的聚丁二烯交联。 在各种研究中，在制备 6-羟基多巴胺储备液过程中，可以添加偏亚硫酸氢钠作为氧化剂。

The Neural Cell Adhesion Molecule (NCAM) plays a crucial role in development of the central nervous system regulating cell migration, differentiation and synaptogenesis. NCAM mediates cell-cell adhesion through homophilic NCAM binding, subsequently resulting in activation of the fibroblast growth factor
