At the isoelectric point, amino acids are present as

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. The isoelectric point of an amino acid is

A parallel plate capacitor is connected to a battery of constant emf. Let the electric field at a given point between the plate be E_(0) , when there is no medium between the plates. The new electric field at the point, If a medium of dielectric constant A is intoduced between them, is

At isoelectric point the amino acids have least /maximum solubility in water.

An amino acid reacts with 10ml 0.05MNaOH and the final solution has pH=2.30 When 20ml of these base is added in the resulting solution.The pH become 9.7 .Identify the amino acid and calculate the isoelectric point of the amino acid.This amino acid is prepared by the reaction of compound (X) with NH_(3) and further hydrolysis with HCN compound (X) is less C atom containing compound that gives postitive iodoform test and positive Fehling's solution test. Isoelectric point of the amino acid is:
