1. Identify the structural formula. Use these choices:
a.
amino acid
b.
maltose
glucose
In your book, read about carbon compounds, carbohydrates, lipids, proteins, and nucleic acids.
Examine each group of terms. Cross out the one term that does not belong with the
others, then write a name for the group. Use these choices:
c.
proteins
_glucose_
_amino acid_
_maltose_
For each statement, write the letter of one of the structural formulas in number 1
above. A letter can be used more than once.
