Carbohydrates • monomer is SACCHARIDE • simple sugars are one monomer - a monosaccharide • the carbon, hydrogen, and oxygen are in a 1:2:1 ratio Form Rings
Carb Facts! • function in storing energy for easy access for plants and animals • starches and sugars • Example: Glucose (C6 H12 O6) which is a monosaccharide used by all living things!
MonosaccharideEx: ribose and deoxyribose Disaccharide Ex: sucrose- table sugar Why are they called disaccharides? Polymer-a large molecule made up of smaller molecules
Carbohydrates • POLYSACCHARIDE is a carbohydrate made of long chains of sugars (3 or more monosaccharides) • Starch - Plants convert excess sugars into starches for long-term storage • Glycogen -Animals store glucose in the form of polysaccharide glycogen in the liver and muscles to be used as quick energy • Cellulose -a structural polysaccharide contained in the cell walls of plants • Chitin – a polysaccharide found in the cell walls of fungi and the exoskeletons of insects and arthropods
Dehydration Synthesis Releases Water when the bond is formed.
Hydrolysis • chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. One fragment of the parent molecule gains a hydrogen ion (H+) from the additional water molecule. The other group collects the remaining hydroxyl group (OH−).
Testing for Carbs • How do you know something contains carbohydrates? • Test with Benedict’s Solution • An indicator that changes color in the presence of disaccharides
