Protein

 PROTIEN

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. Proteins contain hydrogen, oxygen, nitrogen, and carbon.

Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein

The monomers of protein is amino acid

The structure of amino acids determine the proteins shape, size.

The functions of protein:

Protein helps repair and build your body’s tissues. It drives metabolic reactions, maintains pH and fluid balance, and keeps the immune system strong. It also transports and stores nutrients and can act as an energy source.

Protein is crucial to good
health.

1. Growth and maintenance 

2. Causes biochemical reactions 

3. Acts as a messenger 

4. Provides structure

5. Maintains proper pH

6. Balances fluids

7. Bolsters immune health 

8. Transports and stores nutrients 

9. Provides energy

POLYPEPTIDE:

Its a polymer of amino acids joined by a covalent bond, known as a peptide bond.

the function of polypeptides in proteins:

DNA replication

LAB:

We did an experiment in the lab about which one these substances has the most amount of protein. The 4 substances were egg white solution, milk, soda, and water. With these substances we added biuret solution into each one of them to see which one has the most protein, and with doing so we realized that the egg white solution had the most protein.

Why do we need to eat foods that contain proteins?

Because it’s needed for growth and to repair the body tissues and is really important for healthy muscles and bones.

How many times a day should we consume foods that contain protein?

Every 2-3 hours.
