1. Proteins are one of the main structure of most function of cells. 2. A protein is a polymer constructed from a set of just 20 kinds of monomers called amino acids.
3. They form structure of such as hair and fur, muscles, and provide long-term nutrient storage.
4. Proteins are created by cells and cells create proteins by linking amino acids together into a chain called a polypeptide.











Questions:


1. Give at least two examples of proteins you can "see" in the world around you. What are their functions?
Egg white(non-fried), hair. They make up muscles and provide nutrient storage.




2. Relate amino acids, polypeptides, and proteins.
Amino acids make up proteins and polypeptides but polypeptides are in a shape of a chain and proteins are not




3. Explain how heat can destroy a protein.
When heat get into a protein, it can make it lose it's normal shape, this process is called denaturation.




4. Which parts of an amino acid's structure are the same in all amino acid? Which part is unique?
All Amino acid monomers contains carbon.
It's unique part is the difference of the side group
