what is the difference in monosacchrides, disaccharides, andpolysacchrides?
What are the structures of glucose, frustose, sucrose, lactose,and starch, such that you could predict their responses in thefollowing tests:
Benedicts test (remains bright blue if negative for a reducingsugar, turns any other color if positive for reducing sugar. Testsfor free or potentially free aldehyde or ketone groups)
Seliwanoff’s Test (turns red or pink, speed of color changeindicates ketose vs. aldose, and monosacchride vs.disaccharide)
Iodine Test – tests for polysaccharides, turns blue-black instarch, red-to-brown color in other polysaccharides
