◉ What is the L configuration of a sugar in a Fisher projection?
Answer: hydroxyl on left
◉ What is the difference between glycogen and amylopectin?
Answer: glycogen- has branches about every 10 residues (more highly
branched)
amylopectin- has branches about every 25
◉ What is amylose made up of?
Answer: glucose
◉ What makes up starch?
Answer: amylose
amlyopectin
◉ What is a glycosidic bond?
