We will consider the Grignard chemical deacylation to study the regioanalysis of triacylglycerols (TAGs). Using a given TAG structure, a cross-contamination model is developed and used for evaluating the incidence of the acyl migration and its influence on the accuracy of a regiospecific analysis of the molecule. Despite unavoidable isomerization, the newly formed alpha,beta-diacylglycerols are considered as most representative of the original TAG composition. In this paper, we present evidence that in conditions of limited acyl migration, the regiospecific distribution could more accurately be determined from the alpha-monoacylglycerol rather than through calculations based on the alpha,beta-diacylglycerols fraction.

酰基迁移率对三酰基甘油区域分析准确性的影响-理论评估。

我们将考虑使用格氏化学脱酰来研究三酰基甘油（TAGs）的区域分析。使用给定的TAG结构，开发了一种交叉污染模型并将其用于评估酰基迁移的发生率及其对分子区域特异性分析准确性的影响。尽管不可避免地发生异构化，但是新形成的α，β-二酰基甘油被认为是最原始TAG组成的代表。在本文中，我们提供了证据，表明在酰基迁移受限的情况下，可以通过α-单酰基甘油而不是通过基于α，β-二酰基甘油分数的计算来更准确地确定区域特异性分布。
