Most common element present in human body is:
1. | Oxygen | 2. | Carbon |
3. | Hydrogen | 4. | Sulfur |
When we homogenize any tissues in an acid the acid soluble pool represents

Amino acids, as the name suggests, have both an amino group and a carboxyl group in their structure. In addition, all naturally occurring amino acids (those which are found in proteins) are called L-amino acids. From this, can you guess from which compound can the simplest amino acid be made?
1. | Formic acid | 2. | Methane |
3. | Phenol | 4. | Glycine |
1. | Thymine | 2. | Thymosine |
3. | Thymidylic acid | 4. | Cytidylic acid |
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:
1. Glutamic acid | 2. Lysine |
3. Arginine | 4. Histidine |
The simplest α amino acid is:
1. Glycine | 2. Alanine |
3. Serine | 4. Lysine |
