What is Zwitterions.

What is a Zwitterion ? Or what is an isoelectronic point?

What is the Zwitterion?

Assertion (A)Glycine exists as Zwitterion. Reason ( R) It behaves as Lowry-Bronsted acid and base.

(A) Alpha amino acids generally exists as zwitterions. (R) The basic amino groups of alpha -amino acids donates a proton to the carboxylic group.

All proteins are made up of alpha -amino acids which act as the building blocks. alpha -amino acids that are synthesised in the body, are known as non-essential alpha -amino acids while the one which the body fails to synthesise, are called essential alpha -amino acids. All of them exist as dipolar ions also known as Zwitterions. For all the alpha -amino acids, there is a certain pH of the medium known as isoelectric point at which the dipolar ions behave as electrically neutral species. In acidic medium, the ion migrates towards cathos while in basic medium, it migrates towards anode on passing electric current. Which of the following is not an essential alpha -amino acid ?
