Lignin inter-monomeric and end-unit linkage types in undigested and digested diets of N. hirtum. Oxygenated aliphatic (a and c) and aldehyde (b) sub-regions of 2D HSQC NMR spectra of pine wood and Shorea artificial diet lignocellulose samples before (“original”) and after (“digested”) digestion by N. hirtum larvae. Boxes labeled × 2 represent regions with the scale vertically enlarged by twofold. In d, normalized signal intensity values of the major lignin inter-monomeric linkage types (Iɑ, IIɑ and ½IIIɑ) and aldehyde (IV′γ and IV′′ɑ) and HPV/HPS (½IV′′′β) end-unit signals expressed as percentages of Iɑ + IIɑ + ½IIIɑ are shown. Data labeled × 5 indicate that the reported values are multiplied by 5 for visualization purposes. Peak assignments are listed in Table 2
