Proteins
Chapter 6
Proteins
Chemistry in Biology
 A compound made of small carbon compounds
called amino acids
 Amino acids are small compounds that are
made of carbon, nitrogen, oxygen, hydrogen,
and sometimes sulfur.
Characteristics of Proteins
• Amino acids (monomers) are the basic
building blocks of polypeptides (polymers)
and polypeptides form proteins.
• Functions:
– structural components of cells
– catalyzing chemical reactions (enzymes)
– transporting substances within cells
– messenger molecules (hormones)
Chapter 6
Proteins
Chemistry in Biology
 Amino acids have a central carbon atom.
 One of the four carbon bonds is with hydrogen.
 The other three bonds are with an amino group
(–NH2), a carboxyl group (–COOH), and a
variable group (–R).

Chapter 6
Structures of Proteins
Chemistry in Biology
 The number and the order in which the amino
acids are joined define the protein’s primary
structure.
 After an amino acid chain is formed, it folds into a
unique three-dimensional shape, which is the
protein’s secondary structure, such as a helix or a
pleat.
Summary
• Write of brief, comprehensive summary (3-4
sentences) of your notes, focusing on the main ideas
and concepts.
• Be prepared to share you summary with your
classmates.
Chapter 6
Chemistry in Biology
Nucleic Acids
 Nucleic acids are complex macromolecules that store
and transmit genetic information.
 Nucleic acids are made of smaller repeating subunits
called nucleotides, composed of carbon, nitrogen,
oxygen, phosphorus, and hydrogen atoms.

Summary
• Write of brief, comprehensive summary (3-4
sentences) of your notes, focusing on the main ideas
and concepts.
• Be prepared to share you summary with your
