B-type starch

WebNov 27, 2024 · In the current structure model of starch polymorphs, B-type starches contain more water molecules between double helices than A-type starches. The water molecules in the interhelical space of the B-type structure have a higher degree of freedom and a different local molecular environment. WebThe larger granules, A-type, are bigger than 10 mm in diameter, a lenticular shape being the first to develop in the endosperm, whereas the B-type starch granules are smaller than 10 mm in diameter and approximately spherical (Lan et al., 2008).
