Review for Test Ch. 4,5,7,8
Key Ideas: (found in notes primary, book as reference)
 Properties of Carbon that make it so
important to life
 Draw basic organic structures (using
prefixes and suffixes
 Functional groups and their
properties
 Role of dehydration reaction in
formation of organic compounds
 Hydrolysis in the digestion of organic
compounds
 Recognize the four biological organic
compounds (carbohydrates, lipids,
proteins, and nucleic acids)
 Form and functions of biological
organic compounds
 Four structural levels of proteins and
functions
