What is the color of a solution when starch is added?
Benedicts tests for the presence of monosaccharides. It will turn a yellow to red color if it is a positive test, but it does not so starch does not contain monosaccharides. ...Actually..... If starch is heated at 250 degrees Celsius, it breaks down into sugar! a saccharide! The intense heat denatures the the starch and transforms it into sugar. Also, if you have starch and amylase ( enzyme found in your saliva) and heat that to 37 degrees Celsius, you will also get a sugar, but in the form of glucose!
