Many organic substances are negatively charged e.g., acetic acid, while others are positively charged e.g., ammonium ion. An amino acid under certain conditions would have both positive and negative charges simultaneously in the same molecule. Such a form of amino acid is called
1. | Positively charged form | 2. | Negatively charged form |
3. | Neutral form | 4. | Zwitter ionic form |
Which of the following is not an aromatic amino acid?
1. Phenylalanine | 2. Threonine |
3. Tyrosine | 4. Tryptophan |
An amino acid that is negative charged amongst the following will be:

3. Serine | 4. Lysine |
1. | Glycine | 2. | Alanine |
3. | Serine | 4. | Lysine |
1. | Lysine | 2. | Histidine |
3. | Arginine | 4. | Valine |
