A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human
Evgen [1.6K]

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.
