Question

Choose the correct answer from the alternatives given:
The amino acids we cannot synthesize are called _____ and we______

• A. Unnecessary; therefore do not need them
• B. Limiting; must include them in our diet
• C. Anabolic; must use alternative amino acids
• D. Essential; must include them in our diet

Answer 1

Answer: (D)

Essential; must include them in our diet

There are 20 amino acids known. Out of these 20, 10 are considered as essential amino acids and the other 10 are considered as non-essential amino acids.

Essential amino acids include arginine, histidine, methionine, isoleucine, leucine, lysine, phenylalanine, tryptophan, threonine and valine.

Non essemtial amino acids include alanine, asparagine, asparatic acid, glutamine, glutamic acid, glycine, cysteine, proline, serine and tyrosine.

The essential amino acids cannot be synthesised by our own body, therefore, should be necessarily included in our diets.

Hence, the correct answer is 'Essential; must include them in our diet'
