Which one of the following statements is not correct?
Options
- AExcept glycine all other naturally occurring -amino acids are optically active
- B-amino acids have maximum solubility at their isoelectric point
- CA tripeptide has two peptide bonds
- D-amino acids exist as Zwitter ions
Correct answer
B. -amino acids have maximum solubility at their isoelectric point
Step-by-step solution
At isoelectric point, the amino acids have the least solubility in water and this property is used for the separation of different amino acids obtained from the hydrolysis of proteins.
