What is the Zwitterion?

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

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 ?

(a) Write Zwitterion structure of glycine. (b) What is dematuration of proteins ?

Refer to the given graph showing state of ionisation of zwitterion. Select the correct statements regarding zwitterion. (i) Zwitterions can be formed from compunds that contain both acid groups and basic groups in their molecules. (ii) A zwitterion can act either as proton donor or proton acceptor. (iii) A monoamine monocarboxylic alpha -amino acid is a acid at high pH as both the groups (amino and carboxyl) lose a proton. (iv) Amino acids in solution at neutral pH exist predominantly as dipolar ions, the amino group is protonated (-NH_(3)^(+)) and the carboxyl group is deprotonated (-COO^(-)) .
