syntheses; recrystallization and flash chromatography for purification of partial acylglycerols; and thin‐layer chromatography (TLC) separation of DAG. For this work, 1‐MAG intermediates and subsequent diacid 1,3‐DAG were prepared using non‐enzymatic methods, whereas, monoacid 1,3‐DAG were prepared by enzymatic methods. It was not always possible to obtain pure samples of target compounds—in recrystallizations
介绍了制备1,3-DAG的完整方法(包括合成,纯化和分析)。对于成功的综合项目,应考虑每个特定过程的优点和缺点,并应采取措施来弥补或平衡潜在的缺点。为此,我们描述了与以下相关的一些挑战:化学和酶催化的酰基甘油合成;重结晶和快速色谱法纯化部分酰基甘油;和DAG的薄层色谱(TLC)分离。对于这项工作,使用非酶法制备1-MAG中间体和随后的二酸1,3-DAG,而通过酶法制备单酸1,3-DAG。f。此外,DAG的TLC R f由两个主要因素决定:酰基链长度和位置异构性。有趣的是,虽然位置异构的作用众所周知,但酰基链长度在这些分离中的作用只是最近才被发现。
