​Proteins

​What are proteins made up of?

Multiple Choice

Which indicator can be used to test for the presence of protein?

• Benedicts

• Iodine

• Biuret

• Sudan Red

• Paper Bag

​Proteins

• Proteins contain the elements Carbon, Hydrogen, Oxygen, and Nitrogen (CHON)​

• Proteins are biomolecules or ​polymers.

  • Proteins are made up of re​peating units of amino acids

  • There are 20 different AA's that can be combined to make a protein

​Structural Formula for Amino Acids

​Amino Acids (there are 20 different ones) differ by their R group

Multiple Choice

The monomer of a protein is....

• Amino acids

• Fatty acids

• Glucose

• Starch

​- 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?

- Breakdown of a molecule by addition of water

​Hydrolysis (digestion)

​- Formation of a molecule by removal of water

​Dehydration Synthesis
