(plus I just took a test with this question)
A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.
- All living organisms, from bacteria to people, depend on amino acids for survival.
- The same 20 types of amino acids are present in all living things.
- Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
- Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.
