A beta turn is a turn in the primary structure, stabilized by hydrogen bonding. Because Proline has an odd, cyclic structure, when it forms peptide bonds, it induces a bend into the amino acid chain. I challenge you to draw the peptide chain with proline; you will see it.

WebThe isoelectric point of an amino acid is the pH at which the amino acid has a neutral charge. You will learn how to calculate the isoelectric point, and the effects of pH on the amino acid's overall charge. We will also discuss zwitterions, or the forms of amino acids that dominate at the isoelectric point.
WebOct 1, 2006 · Histidine is the only amino acid whose protonation state changes near this pH value (pK a ≈ 6–7). Generally, histidine is considered uncharged at neutral pH, and it becomes doubly protonated and positively charged at pH ≈ 6 and below, although the effective pK a of a specific histidine depends on its local environment. field hockey big ten tournamentWebNov 15, 2012 · Histidine (His) residues in proteins can attain three different protonation states at normal pH.
