Chapter 4 Objectives Anette Paez Name _________________________ Again, this chapter is a review of previously covered material. We will be moving
through the material very quickly, please see me for extra assistance if needed.
1. Why is organic chemistry so important in the study of biology?
All living things are made of cells, which are built into organic compounds
using carbons (DNA, RNA, Proteins, Carbs, Lipids)
2. Why was the Urey-Miller experiment so important?
Similar chemical reactions he conducted in his experiment, may have set the
stage for the origin of life on Earth (synthesis of some organic molecules)
3. What is special about carbon that makes it the central atom in the chemistry of
The electron configuration of carbon gives it covalent compatibility with many
different elements (Versatile building with 4 bonds) 4. Use the diagram below to label and contrast the three types of isomers. structural isomers
geometric isomers enantiomers Page 1 of 2 5. Create a table below: after each functional group – draw the structure, name the
compound, write and example and note the functional properties – (doesn’t this
look like great quiz material?)
Hydroxyl Group- Compounds
polar; can form H bonds with water
b. Carbonyl aldehyde Aldehyde end
Found in sugars c. Carbonyl ketone Ketone middle
Found in sugars d. Carboxyl Carboxylic acids
source of H(pos) e. Amino amines
acts as a base; picks
a pH(pos) from
f. Sulfhydryl Thiols
Stabilizes protein structure
g. Phosphate Organic Phosphates
Contributes neg. charge; Can react
with water, releasing energy (ATP
to ADP (energy)) Page 2 of 2 ...
