검증된 단계별 안내1
Understand the structure of each polysaccharide: Cellulose, Glycogen, Starch, and Chitin.
Cellulose is composed of β-D-glucose units linked by β(1→4) glycosidic bonds.
Glycogen is a branched polysaccharide made of α-D-glucose units linked by α(1→4) glycosidic bonds with α(1→6) branches.
Starch consists of two types of molecules: amylose (linear) and amylopectin (branched), both made of α-D-glucose units.
Chitin is composed of N-acetylglucosamine units, which are modified glucose molecules where an acetyl group is attached to the nitrogen atom of the glucose's amine group, making it a modified monosaccharide.
