Webb13 C NMR spectra of native starches are typically analyzed as a composite of spectra from the amorphous (single chain) and the ordered double-helical components (Gidley and Bociek 1985). 13 C NMR spectrum of amorphous starch is often much broader than crystalline starch owing to broader conformational distributions. WebbActive site . The active site of HPA is a deep C-shaped pocket, formed by a cleft between the A and B domains. This site contains a trio of acidic amino acids (Asp197, Glu233, and Asp300) that together cleave α-(1,4) linkages in starch chains of 3 or more D-glucose units to produce shorter oligosaccharides with α-(1,4) and α-(1,6) linkages (Figure 7a).
