一般描述
用于质量控制的经认证的制药二级标准品，为制药实验室和制造商提供了一种方便且经济的替代方案，可用于内部工作标准品的制备。硫胺素焦磷酸是转酮酶的辅酶，转酮酶催化核酮糖-5-磷酸裂解，生成D-甘油醛-3-磷酸。该反应需要加入受体醛，例如核糖-5-磷酸、甘油醛或乙醇醛。
应用
这些二级标准品是合格的认证标准物质（CRM）。它们适用于多种分析应用，包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。
分析说明
这些二级标准品可追溯至USP、EP（PhEur）和BP一级标准品。

Obesity surgery is acknowledged as a highly effective therapy for morbidly obese patients. Beneficial short-term effects on common comorbidities are practically undisputed, but a growing data pool from long-term follow-up reveals increasing evidence of potentially severe nutritional and pharmacological consequences.
