Question

Define isoelectric point taking glycine and example

Answer 1

It is the ph at which the molecule is electrically neutral.

Glycine is the derivative of acetic acid and it's isoelectric point will be centered between the pH of the two ionizable groups that is carboxylic acid and amino acid group

Answer 2

Explanation:

The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I).[1] However, pI is also used.[2] For brevity, this article uses pI. The net charge on the molecule is affected by pH of its surrounding environment and can become more positively or negatively charged due to the gain or loss, respectively, of protons (H+).
