1. How much 5 m KOH must be added to 1.0 L of 0.1 M glycine at pH 9.0 to bring its pH to exactly 10.0?

Why are proline and glycine found so frequently in collagen?

For an α-helical polyalanine peptide 45.00 residues in length, calculate the melting temperature in °C. Tm= °C

Calculate the melting temperature of a 45.00 amino acid α-helical peptide if that peptide contains all alanines and a single internal glycine residue. Tm= °C

Calcuate the melting temperature if the 45.00 amino acid α-helical peptide contains 5.00 internal glycine residues and a glycine at the N-terminus of the helix. Tm= °C

Calculate the melting temperature for a 45.00 amino acid polyhistidine peptide at physiological pH in a 310-helix. Tm= °C
