1H-13C HSQC difference spectrum showing only the components resulting from addition of sulfur in the DMSO swellable fraction. Assignments in 1, phenylalanine (from peptide/protein); 2, tyrosine (from peptide/protein); 3, unsaturations (HC=CH) in lipids, 4, anomeric protons (carbohydrates); 5, other CH in carbohydrates; 6, CH2 in carbohydrates; 7, α-protons in peptides and proteins; 8, methoxyl in lignin; 9, aliphatic linkages including signals from various lipids, and side chain protons in peptides.
