WebJan 1, 1996 · Molecular structure of amylose and amylopectin. Longer amylose molecules tend to make a product's texture stringy because of the way they associate. The molecular weight of the amylose also affects the elasticity of a gel. Longer molecules tend to associate more strongly and produce stronger, more brittle gels, but there is a limit to this effect. http://chemistry.elmhurst.edu/vchembook/547starch.html
