An in vivo 13C NMR study was performed to investigate whether the relaxation properties of the C-1 carbon of the glucopyranose residues of glycogen changed as the molecule increased in size. There was no change in resonance intensity or linewidth. Therefore, no significant change in T1 or T2 was observed.
进行了一项体内13C核磁共振研究，以调查糖原中吡喃葡萄糖残基的C-1碳的弛豫特性是否会随着分子大小的增加而发生变化。共振强度或线宽没有变化。因此，未观察到T1或T2有显著变化。
