Trick to differentiate essential and non-essential amino acids

Amino acids are the building blocks of proteins and are classified as essential and non-essential depending on the body's ability to synthesize them. Essential amino acids are those that cannot be synthesized by the body and must be obtained through diet, while non-essential amino acids can be synthesized by the body. Here's a trick to differentiate between essential and non-essential amino acids:

Remember the acronym "PVTTIM HALL"
- PVTTIM HALL stands for Phenylalanine, Valine, Threonine, Tryptophan, Isoleucine, Methionine, Histidine, Arginine, Leucine, and Lysine.
- The first 6 amino acids, PVTTIM, are essential amino acids, while the remaining 4, HALL, are non-essential amino acids.

Explanation in details

1. Amino acids
Amino acids are the building blocks of proteins. There are 20 different amino acids that combine in various ways to form proteins.

2. Essential amino acids
Essential amino acids are those that the body cannot synthesize and must be obtained through the diet. There are nine essential amino acids: phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, histidine, arginine, leucine, and lysine.

3. Non-essential amino acids
Non-essential amino acids are those that the body can synthesize on its own. There are 11 non-essential amino acids: alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, tyrosine, and ornithine.

4. PVTTIM HALL
To remember the essential and non-essential amino acids, you can use the acronym PVTTIM HALL. The first six letters, PVTTIM, represent the essential amino acids, while the remaining four letters, HALL, represent the non-essential amino acids.

5. Phenylalanine (P)
Phenylalanine is an essential amino acid that is important for the synthesis of neurotransmitters, such as dopamine and norepinephrine.

6. Valine (V)
Valine is an essential amino acid that is important for muscle growth and repair.

7. Threonine (T)
Threonine is an essential amino acid that is important for the synthesis of proteins and the formation of collagen.

8. Tryptophan (T)
Tryptophan is an essential amino acid that is important for the synthesis of serotonin, which regulates mood and appetite.

9. Isoleucine (I)
Isoleucine is an essential amino acid that is important for muscle metabolism and energy production.

10. Methionine (M)
Methionine is an essential amino acid that is important for the synthesis of proteins and the metabolism of fats.

11. Histidine (H)
Histidine is an essential amino acid that is important for the synthesis of histamine, which is involved in immune responses.

12. Arginine (A)
Arginine is a non-essential amino acid that is important for the synthesis of nitric oxide, which regulates blood flow and immune function.

13. Leucine (L)
Le
