FINAL EXAM REVIEW
1. WHAT DO YOU UNDERSTAND BY ORGANIC COM-
POUNDS?
•There can be various definitions of organic compounds but according to a biologist, organic
compounds are the type of compounds that contain carbon which include carbohydrates, pro-
teins, lipids and nucleic acids.
•In fact, all organic compounds are covalently bonded molecules, and many are large.
•Not only organic, but inorganic compounds or molecules such as water, salts and many acids
and bases are also equally essential for life.

•As it is seen that carbon is the basis of life.
•Everything that is found on this earth has carbon in it in one or the other form; or to put it in
another way there would be no life without carbon or its sources.
•Carbon chains form the backbone of most organic compounds or molecules.
•Isomers have the same molecular formula but different in structures.

Document Summary
Final exam review: what do you understand by organic com- 3. 1 life"s molecular diversity is based on the properties of car- bon : Isomers have the same molecular formula but different in structures. 3. 2 a few chemical groups are key to the functioning of biologi- cal molecules : the sex hormones testosterone and estradiol (a type of estrogen) differ only in the groups of atoms. 3. 3 cells make large molecules from a limited set of small mole- 3. 4 carbohydrates: the other name for sugar monomers is monosaccharides, a monosaccharide has a formula that is a multiple of ch. Disaccharides: which are two monosaccharides covalently bonded together which in- clude glucose and fructose which form sucrose as examples. Polysaccharides: which are many monosaccharides (basic building blocks) bonded together, which include glycogen (animals) and starch (plants) as examples. Animals do not have enzymes that can hydrolyze the glucose linkages in cellulose. 3. 8 fats are lipids that are mostly energy- storage molecules.
