Essential Amino Acids | Mnemonic and Easy Way to Remember

The video discusses essential amino acids, which cannot be synthesized by the body and must be obtained through diet. It details each essential amino acid, including phenylalanine, valine, tryptophan, threonine, isoleucine, methionine, histidine, arginine, leucine, and lysine. A mnemonic, 'Private Tim Hall,' is introduced to help remember them. Arginine, cysteine, and tyrosine are conditionally essential. The video also highlights amino acids limited in plant-based diets, such as phenylalanine, methionine, threonine, and lysine, and concludes with a summary of their importance.

Which amino acid is characterized by a benzene ring attached to an alanine backbone?

• Phenylalanine

• Tryptophan

• Valine

• Threonine

What is unique about the side chain of valine?

• It has a sulfur group

• It includes a hydroxyl group

• It has a branched chain in the form of a V

• It contains a benzene ring

Which amino acid is sometimes considered essential only during childhood?

• Lysine

• Arginine

• Histidine

• Methionine

What happens to cysteine when methionine is not adequately consumed?

• It is converted to tyrosine

• It becomes essential

• It becomes non-essential

• It is synthesized from phenylalanine

Which amino acids are typically deficient in plant-based diets?

• Tryptophan, Histidine, Arginine, Methionine
