how many amino acids are there in a complete protein
The term complete protein refers to amino acids, the building blocks of protein. There are 20 different amino acids that can form a protein, and nine that the body canât produce on its own. These are called essential amino acids âwe need to eat them because we canât make them ourselves. In order to be considered âcomplete,â a protein must contain all nine of these essential amino acids in roughly equal amounts. Yes, meat and eggs are complete proteins, and beans and nuts arenât. But humans donât need every essential amino acid in every bite of food in every meal they eat; we only need a sufficient amount of each amino acid every day.
