2. What is Collagen?
Collagen is a type of protein can be found in mammals and humans. Collagen basically supports skin, teeth, cartilage, bones, tendons and muscle. Collagen makes up 25% of our proteins in our body. Collagen is basically like a glue that holds our body/parts together. If we didn’t have Collagen then our bodies would fall apart.

3. What Other Organisms use this Protein?
Collagen can be found in Humans, and Animals.

4. Structure Of Collagen
Collagen is a fibrous protein molecule . These fibers intertwine with each other just like a rope. They are very tough and can resist a pulling force. Collagen contains large amounts of glycine and proline, as well as two amino acids that are not inserted directly by ribosomes.

6. Why I chose this Protein?
I chose this Protein because I never knew played a big part of our life. For instance growing up and getting older. Collagen ages when we get older. It develops wrinkles in our skin that makes us look older.
