Verified step by step guidance

Understand the definition of essential amino acids: Essential amino acids are those that cannot be synthesized by the human body and must be obtained through dietary sources.

Differentiate between essential and non-essential amino acids: Non-essential amino acids can be synthesized by the body, whereas essential amino acids cannot.

Consider the role of essential amino acids in nutrition: Since the body cannot produce these amino acids, they are crucial components of a balanced diet.

Evaluate the options given in the problem: Identify which option correctly aligns with the definition of essential amino acids.

Recognize the importance of essential amino acids during various life stages: Essential amino acids are always required, not just during periods of rapid growth.
