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

Model the structure of the following carbohydrates:Amylose

AmylopectinGlycogen

For each:What is it formed up of?

What is the function?

Looking at amylose and amylopectin what are the differences? Why are there these differences?

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.
