Properties of
Proteins
Proteins
Have Many Different Biological Functions
Proteins
Are Very Large Molecules
Proteins
Have Characteristic Amino Acid Compositions
Some
Proteins Contain Chemical Groups Other Than Amino
Acids
Working with
Proteins
Proteins
Can Be Separated and Purified
Individual
Proteins Can Be Quantified
Proteins
Can Be Characterized by Electrophoresis
The
Antibody-Antigen Interaction Is Used to Quantify
and Localize Proteins
The Covalent
Structure of Proteins
The
Function of a Protein Depends on Its Amino Acid
Sequence
The Amino
Acid Sequence of Polypeptide Chains Can Be
Determined
Short
Polypeptides Are Sequenced Using Automated
Procedures
Large
Proteins Must Be Sequenced in Smaller Segments
Amino Acid
Sequences Can Be Deduced from DNA Sequences
Amino Acid
Sequences Provide Important Biochemical
Information
Homologous
Proteins from Different Species Have Homologous
Sequences
