​Group of biological molecule :​

​Proteins

​Elements:

​Proteins are made of amino acids.

​amino acids are small compounds that are made of carbon , nitrogen, oxygen , hydrogen , and sometimes sulfur.

​Overall structure :

​Amino acids share the same general structure.

​Function in living organism :

​Proteins make up 15 percent of human body and are involved in nearly

​every function of the body . Muscles , skin , and hair are made of protein cells contain 10,000 different proteins which provide structural support, chemical reaction ,and control cell growth .

​
