The direct incorporation of U-13C glucose was estimated by the intensity increase of m/z to F(F was parent fragment, and n was the carbon number in the fragment), while the total isotope incorporation from the added 13C could be calculated according to the abundance ratio increment summation from m/z (Fa+1) through (Fa was the fragment containing all original skeleton carbons, and T was the carbon number in the amino acid molecule). The 13C enrichment in the target compound was expressed as atom percentage excess, and that of D-amino acid needed to be corrected by the coefficient of hydrolysis-induced racemization. The 13C enrichment reflected the carbon turnover velocity of individual amino acid enantiomers, and was powerful to investigate the dynamics of soil amino acids.
外加葡萄糖直接合成氨基酸的比例可利用质谱碎片的相对强度变化来评价(n为质谱碎片F中含有的碳原子数目);而源于葡萄糖的13C同位素在氨基酸分子中的富集程度是所有同位素峰相对强度变化的总和。13C在目标化合物中的富集比例用原子百分超评价,D氨-基酸的APE还需进一步利用水解诱导的外消旋化系数校正。13C在目标化合物中的富集程度可反映各氨基酸手性异构体的碳循环速率大小,是研究土壤氨基酸动态变化的有力工具。
