Net charge of a peptide at ph 7

WebSo the ph scale just provides scientists and chemists with a very compact method to represent the solution acidity. So because the proton iron source in an aqueous solution is typically quite small, we use the P scale in the form of the ph scale that provides a convenient way to represent the solution acidity. WebAn antimicrobial peptide, known as V13K, was utilized as the framework to study the effects of charge, hydrophobicity and helicity on the biophysical properties and biological activities of α-helical peptides. Six amino acids (Lys, Glu, Gly, Ser, Ala, and Leu) were individually used to substitute the original hydrophobic valine at the selected sixteenth location on …
