Amylose and amylopectin and starch

Starch = alpha 1-4 glucan : two parts

What is reducing sugar?

Can open up their ring and then have a double o bond which is reactive (aldehyde group and so glucose can change from alpha to beta gluicose

Reducing sugar aldehyde

Aldhyde group R-C (double O and 1 H) react with copper forms a red colour , can be measured with spectrohptometer, can then be against glucose standard conc. To measure the amount of reducing ends
