From: A rapid method for quantifying free and bound acetate based on alkylation and GC-MS analysis
The effect of sodium hydroxide added during the derivatization on hydrolysis of bound acetate. Whisker plot for the relative acetate background derived from procedure blank and N-acetylated biomolecules—BSA, N-acetyl-l-aspartate (NAA) and N-acetyl-l-cysteine (NAC). No significant deacetylation occurs during the derivatization procedure. Data are means ± SD of n = 5 for all conditions. Horizontal line and dot on box plot correspond to median value and outlier, respectively. Upper and lower end of box plot vertical line are maximum and minimum determined values, respectively
