What do Biochemists study? - ANSWER 1. The relationship between structure and function of
biomolecules
2. Chemical reactions of organisms
3. Communication within and among organisms
Smaller elements are favored because they can form stable covalent bonds. T or F - ANSWER True.
Strong bonds form by significant overlap of atoms, such as carbon and hydrogen, allowing them to share
electrons.

Condensed structures give a better idea of a molecules structure, compared to chemical formula. T or F -
ANSWER T
Structural formula gives an even better idea of a molecules structure, compared to chemical formula -
ANSWER T
Advantage of cyclic carbon compounds - ANSWER They are more restricted in their movements and
orientation - advantageous for building structures and maintaining shape
Carbon can form double and triple bonds with other carbon atoms or atoms of other elements. T or F -
ANSWER T
Line-bond Drawing - ANSWER Most efficient method to show structure, but requires the most
interpretation.
Functional group - ANSWER specific arrangement of atoms; they define the chemistry of the molecule
and control the properties of the compound.
