Verified step by step guidance1
Step 1: Understand the concept of essential amino acids. Essential amino acids are those that cannot be synthesized by the human body and must be obtained through the diet.
Step 2: Recall that there are 20 amino acids used to build human proteins. Out of these, some are classified as essential because the body cannot produce them.
Step 3: Identify the number of essential amino acids. Research and nutritional science confirm that there are 9 essential amino acids required in the human diet.
Step 4: Review the list of essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Step 5: Compare the given options (6, 9, 11, 15) and select the correct number of essential amino acids, which is 9.
