Document Summary

Compounds with a ratio of: 1 c 2 h 1 o. Monosaccharides: 1 sugar when put into water, they form 6 ringed carbon. Disaccharides: 2 sugars produced through condensation reaction (dehydration synthesis) dehydration: synthesizing a polymer; removal of water hydrolysis: breaking down a polymer; adding of water. Polysaccharides: many sugars cellulose: structural (sugar in clothes) starch: storage (plants) glycogen: storage (animals) Fatty acids: a hydrocarbon chain with a carboxyl group on one end. Saturated fats: carbons are carrying maximum number of hydrogen; they are single bonded to each other: unsaturated fats: carbon carbon double bonds, reducing the number of hydrogen; actually better for us. Triglycerides (fats: a glycerol molecule with 3 fatty acid chains attached. Phospholipids: a glycerol molecule with 2 fatty acid chains and a phosphate group attached. Steroids: 4 carbon rings with various side groups; three 6-sided rings and 1-5 sided ring (carbon rings)

Can somebody check if my answer is rght? Thank you

Complex carbohydrates

Indicate whether each of the following statements about polysaccharides is True or False.

1. Polysaccharides are long polymers made of many nucleotides that have been joined through dehydration synthesis. False
2. Cellulose is the main storage polysaccharide in plants while glycogen is an important storage polysaccharide in many animals. False
3. Both starch and glycogen are composed of Î±-glucose subunits. True
4. Starch is composed of amylose and amylopectin, which are unbranched and branched chains of Î±-glucose subunits, respectively. False
5. Like amylopectin, glycogen is insoluble in water, but it has a longer average chain length and fewer branches. True
6. Although some polysaccharides are used to store energy, others serve as structural material for cells. True
7. The principal structural polysaccharide in plants is starch. True
8. Cellulose is composed of a long, branched chain of Î²-glucose subunits. True
9. The starch-hydrolyzing enzymes produced by most organisms cannot break the bond between two Î± -glucose subunits because they only recognize Î² linkages. False
10. Chitin is a structural polysaccharide found in the exoskeleton of arthropods and the cell wall of many fungi. True
