Starch ph range
Webbtubes 3 (amylase, starch, pH 7.0 buffer), 7 (amylase, starch, pH 2.0 buffer), and 8 (amylase, starch, pH 9.0 buffer) reveal that amylase activity was highest at pH 7 This activity includes a number of negative controls. Which tube indiciates that the amylase solution was not contaminated with maltose? WebbThe major chemical component of the maize kernel is starch, which provides up to 72 to 73 percent of the kernel weight. Other carbohydrates are simple sugars present as glucose, sucrose and fructose in amounts that vary from 1 to 3 percent of the kernel. The starch in maize is made up of two glucose polymers: amylose,
