Broad resonances at 2.04 and 2.08 ppm in 500 MHz Hahn spin-echo 1H NMR spectra of human blood plasma are assigned to the N-acetyl groups of mobile carbohydrate side-chains (largely N-acetylglucosamine and N-acetylneuraminic acid) of glycoproteins such as alpha 1-acid glycoprotein. Their intensities in spin-echo spectra correlate with clinical conditions in which an elevation of the level of 'acute-phase' glycoproteins is expected, and so may be of value in the study of certain diseases.
在500兆赫哈恩自旋回波1H核磁共振谱中，人血浆2.04和2.08 ppm处的宽共振峰归因于糖蛋白（如α1-酸性糖蛋白）中可移动碳水化合物侧链（主要是N-乙酰葡糖胺和N-乙酰神经氨酸）的N-乙酰基。它们在自旋回波谱中的强度与预期“急性期”糖蛋白水平升高的临床情况相关，因此在某些疾病的研究中可能具有价值。
