Carbohydrates - energy transport - (ANSWERS)glucose in blood
Sucrose in plants
Carbohydrates - building material - (ANSWERS)chitin in arthropod
skeletons
Cellulose in plants
Molecular recognition and communication at the cell surface -
(ANSWERS)membrane glycoproteins and glycolipids, such as the MHC
complex on the surface of our cells
Simple sugar - (ANSWERS)3-7 carbons
Contain hydroxyl and carbonyl groups
Eg. Glucose, galactose, fructose
Disaccharides (and oligosaccharides) - (ANSWERS)two (or a few)
monosaccharides attached together
Eg. Glucose + glucose = maltose

Cellulose - (ANSWERS)principle component of plant cell walls
Glucose linkage: β(1-->4)
Chitin - (ANSWERS)principle component of arthropod exoskeletons and
fungal cell walls
Glucose linkage: β(1-->4)
How are cellulose and chitin different - (ANSWERS)chitin has an acetyl
amine group instead of one of the hydroxyl groups
Hydrophobic - (ANSWERS)not water loving
Hydrophilic - (ANSWERS)water loving
Carbohydrate - (ANSWERS)a simple sugar containing aldehydes or
ketones with 3-7 carbons
