Proteins
Proteins contain the elements Carbon, Hydrogen, Oxygen, and Nitrogen (CHON)
Proteins are biomolecules or polymers.
Proteins are made up of repeating units of amino acids
There are 20 different AA's that can be combined to make a protein
4
Structural Formula for Amino Acids
Amino Acids (there are 20 different ones) differ by their R group
5
Multiple Choice
The monomer of a protein is....
Amino acids
Fatty acids
Glucose
Starch
6
- The product is called a protein
- The special bond is called a peptide
- Many amino acids linked together are called a polypeptide
- Therefore, proteins = polypeptides
How do AA's link together to form proteins?
