Isoelectric point
1. Define Isoelectric Point.
The pH at which a molecule carries an equal amount of positive and negative charge is called the Isoelectric point. It is represented as pI. The isoelectric point can be defined for protein as well as for amino acids.
2. What is Isoelectric Point of Glycine?
The isoelectric point of Glycine 6.06.
3. Define Zwitter Ion.
It is an ionic form that is neutral but carries an equal amount of positive and negative charge.
4. What is Isoelectric Point of Histidine?
The isoelectric point of histidine is 7.59 .
5. What is Isoelectric Point of Casein?
The isoelectric point of casein is found in the range of 4.6 to 5.2.
6. What is Isoelectric Point of Arginine?
The isoelectric point of arginine is 10.76.
7. What is Isoelectric Point of Lysine?
The isoelectric point of Lysine is 9.74.
Isoelectric Point
Isoelectric Point is the basic concept in the field of biochemistry and protein chemistry which plays an important role in understanding the behaviour of molecules in different environments. The isoelectric point is a property of an Amino Acid or protein that is defined as the pH at which a protein molecule carries an equal positive and negative charge.
In this article, we will learn about the isoelectric point as well as the formula for the isoelectric point and also provide a step-by-step guide to help you easily calculate the isoelectric point. So, let’s start with the definition of isoelectric point first.
