Verified step by step guidance

Understand the concept of essential amino acids: Essential amino acids are those that cannot be synthesized by the human body and must be obtained from the diet.

Identify the total number of amino acids: The human body uses 20 different amino acids to synthesize proteins.

Differentiate between essential and non-essential amino acids: Out of the 20 amino acids, some can be synthesized by the body (non-essential), while others cannot (essential).

Recall the number of essential amino acids: The human body requires 9 essential amino acids to synthesize all necessary proteins.

Review the list of essential amino acids: These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
