Each carbohydrate residue is labeled with a unique letter for 36A (A to F) and 36B (A to F). Proton and carbon are indicated by letters H and C, respectively, and the numbers associated with them indicate their respective chemical shift values. A slash separates the proton and carbon chemical shifts (ppm). For each residue, the table shows the chemical shifts of every proton and carbon molecule attached to it at different positions. N-Ac, N-acetylation. 31P, phosphate.
