How Many Different Amino Acids Are There?
There are 20 different amino acids that are commonly found in proteins. These amino acids can be classified into two categories: essential amino acids and non-essential amino acids.
What are Essential Amino Acids?
Essential amino acids are amino acids that cannot be synthesized by the body and must be obtained through the diet. There are nine essential amino acids that humans need to consume in their diet to maintain optimal health.
What are Non-Essential Amino Acids?
Non-essential amino acids are amino acids that can be synthesized by the body and do not need to be obtained through the diet. There are 11 non-essential amino acids that the body can produce on its own.
