The acid used for preliminary separation of biomolecule in a living tissue is
1 trichlorobenzoic acid
2 benzoic acid
3 trichloroacetic acid
4 acetic acid
Explanation:
(c) In order to study the various biomolecules found in living tissues, the living tissues are ground in trichloroacetic acid using a mortar and a pestle to form a thick soup. It is then strained to obtain two fractions : acid soluble and acid insoluble fraction. Chemicals present in both the fractions are further separated by various analytical techniques and identified.

Which of the following shows zwitter ionic form?
(b)
shows zwitter ionic form. Zwitterions
are those ions that are electrically neutral overall but contain non adjacent regions of positive and negative charges. They are sometimes referred to as dipolar ions. Free amino acid found in cells is an example of zwitterion. General structure of an amino acid exposes two parts, or groups, of the molecule that can function as an acid/base pair, the $-\text{COOH}$ and $-\text{N}{{\text{H}}_{2}}$ groups.
