Question

UV spectroscopy of proteins at 280 nm allows for the detection of proteins due to the absorbance of and the amount of absorbance correlates with . aromatic amino acids; concentration aromatic amino acids; mass charged amino acids; concentration charged amino acids; mass Based on your knowledge of amino acids and their properties, which of the following peptides would you expect to be the most hydrophobic? AVRSHK AVDSEQ VAFSWL PLRDKE A peptide bond is planar due to: steric interactions of the amino acid side chains hydrogen bonding charge repulsion esonance (bond delocalization) A given sample of water has a [OH-] concentration of 1.0*10-8 M. The pOH of the solution is solution is . pOH = 6 and pH = 6 pOH = 6 and pH = 8 pOH = 8 and pH = 6 pOH = 8 and pH = 8 pOH = 8 and you cannot determine the pH from the information given
