体外研究 |
Dibenzoyl Thiamine is a thiol-type thiamine composed of thiamine and benzoic acid. It is not decomposed by aneurinase (thiamine-decomposing enzyme), making it more suitable for food processing than thiamine hydrochloride |
体内研究 |
A chronic toxicity study in male Wistar rats for 6 months at dietary levels of up to 1000 ppm, shows Dibenzoyl Thiamine to be without specific toxic effects. A teratogenicity study in rats show Dibenzoyl Thiamine to be without embryotoxic or teratogenic effects. Tests for mutagenicity in bacterial systems, in the dominant lethal assay and in an in vivo cytogenetics test show Dibenzoyl Thiamine to be without mutagenic. Dibenzoyl Thiamine is metabolised to Vitamin Br and benzoic acid, and the benzoic acid moiety is almost quantitatively excreted in the urine, as hippuric acid |
推荐实验方法(仅供参考)
Animal Administration |
Rats: Groups of 65 male and 65 female Sprague-Dawley rats are fed diets containing Dibenzoyl Thiamine at levels of 1000 ppm (Group 1) and 10000 ppm (Group 2). A third group is fed a control diet. The animals are assigned by computer to groups on the basis of body weight, such that mean body weights in all groups are approximately equal. 10 Animals from each group are killed at 52 weeks, the remaining animals at week 105. All signs of ill-health or reaction to treatment are recorded daily. The animals are weighed at weekly intervals |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
