Amino Acid Isoelectric Points The isoelectric point of an amino acid is influenced by its chemical structure, specifically the side chain (R group) that determines its properties. There are 20 common amino acids, each with a unique side chain, and their isoelectric points range from 5.5 to 12.0...

The isoelectric point (pI) of an amino acid refers to the pH at which the amino acid exists in its neutral, or zwitterionic, form. At the isoelectric point, the amino acid carries no net electrical charge because the positive charge on the amino group (+NH3) equals the negative charge on...
Amino acid, any of a group of organic molecules that consist of a basic amino group, an acidic carboxyl group, and a unique organic side chain. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Examples of amino acids include glyci

The seven descriptors selected using GA-PLS, which is a sophisticated hybrid approach that combines GA as a powerful optimization method with PLS as a robust statistical method for variable selection, were used as inputs of RBFNNs and SVM to predict the isoelectric point of an amino acid....

In all cases, the electrical charge of an amino acid in solution is determined by its isoelectric point and the pH of the medium. When the pH is higher than the isoelectric point, the amino acid will carry a negative charge due to the ionization of the carboxyl group. In contrast, when...
