Question

What are essential amino acids?

Hint:

Essential amino acids = Not synthesized in body → Must be taken in food.

Answer 1

Concept:
Amino acids are the fundamental building blocks of proteins. They are categorized into:

• Essential amino acids
• Non-essential amino acids

Definition:
Essential amino acids are those that the human body cannot synthesize in adequate amounts and must, therefore, be acquired through the diet.
Explanation:
Since the body cannot produce essential amino acids, they need to be provided by protein-rich foods such as:

• Milk
• Eggs
• Meat
• Pulses and legumes

Examples of essential amino acids:
Some essential amino acids include:

• Valine
• Leucine
• Isoleucine
• Lysine
• Methionine
• Threonine
• Phenylalanine
• Tryptophan

Importance:
Essential amino acids are crucial for various bodily functions:

• They are required for the growth and repair of tissues.
• They are vital for enzyme and hormone synthesis.
• They play a significant role in immune function.

\[ \therefore \text{Essential amino acids must be supplied through diet.} \]
