Proteins / Peptides
Nature of Proteins Effect of pH on solubility, denaturing proteins, hydrolysis in strong base, binding to coomassie blue, dying wool and cotton, gel filtration column, reaction of ninhydrin with amino acids and precipitating protein with ammonium sulfate are demonstrated.

Denaturation of Protein by Strong AcidJohn W. Moore, Jerrold J. Jacobsen, Gary Trammell, Kristin Johnson "Strong acid denatures egg white proteins.This video contains voiceover:""The tertiary structure of egg white proteins is held together by hydrogen bonding and hydrophobic interactions. Adding strong acid to the protein disrupts the intermolecular forces, and the tertiary structure is lost. The loss in protein structure is called denaturation. The proteins precipitate, forming a white solid."""
Molecules and Medicine (E. J. Corey, Barbara Czakó, and László Kürti)Robert E. Buntrock Looking for a book on common drugs and pharmaceuticals? On diseases and medical conditions? On pharmacology? In addition, do you need some background in chemistry to handle all of this information? If you want all of this, and in addition want it under one cover, then this is the book for you. Buntrock, Robert E. J. Chem. Educ.2008, 85, 1495.

Illustrating the Concepts of Isotopes and Mass Spectrometry in Introductory Courses: A MALDI-TOF Mass Spectrometry Laboratory ExperimentNancy Carter Dopke and Timothy Neal Lovett This article describes a matrix-assisted laser desorption/ionization (MALDI) mass spectrometry experiment in which students prepare peptide samples for mass analysis and then collect and analyze mass spectral data. The lab provides hands-on experience with research instrumentation and reinforces the concepts of isotopes, molecular masses, and molecular formulas. Dopke, Nancy Carter; Lovett, Timothy Neal. J. Chem. Educ.2007, 84, 1968.

A New Colorimetric Assay of Tabletop Sweeteners Using a Modified Biuret ReagentChristopher J. Fenk, Nathan Kaufman, and Donald G. Gerbig, Jr. Presents a new, fast and effective colorimetric analysis of aspartame that incorporates a less caustic biuret reagent and visible spectroscopic analysis for selective detection in aqueous solutions using readily available instrumentation. Fenk, Christopher J.; Kaufman, Nathan; Gerbig, Donald G., Jr. J. Chem. Educ.2007, 84, 1676.
