Identify the correct statement related to amino acids
Options
- ANonessential amino acids cannot be synthesized in the body
- BThese are soluble in ether
- CThese are low melting solid substances
- DIn aqueous solution they exist as zwitter ion
Correct answer
D. In aqueous solution they exist as zwitter ion
Step-by-step solution
Essential amino acids cannot be synthesized in our body so we need to take them in our diet. Amino acids are soluble in water but generally insoluble in organic solvents. Due to crystalline nature, they are high melting solids because of dipole-dipole interactions. They exist as dipolar zwitter ions in aqueous solutions.
