Organic Molecules - Carbohydrates
Monosaccharides • _________ sugars (one molecule)• simplest• *glucose, fructose
Disaccharides • ________ sugars• combination of two monosaccharides• *_________ = glucose + fructose• *_________ = glucose + galactose
Polysaccharides • ____________ composed of several sugars• can be same monomer (many of same monosaccharide) or mixture of monomers• _____________ carbohydrates: glycogen (animals) starch (plants)
• _____________ carbohydrates: chitin (animals), cellulose (plants)
What are carbohydrates?Task

What are carbohydrates?Amylose – Alpha glucose 1-4 links
Amylopectin – Alpha glucose 1-4 and 1-6 branching links.
Glycogen – Similar structure to amylopectin but much more regular branching.
Amylose less readily digested than amylopectin and glycogen.
