Untalan CHEM 160.1 – 1L AY 2013 – 2014 Groupmates: Sonette Yao Kristopher Quilan Laboratory Instructor Carmelo C. Briones I. Introduction Analyzing proteins in determination of protein concentration by spectrophotometry is important. It determines to what concentration of a certain protein is in a crude sample. In this technique‚ a wide

ntroduction In this experiment we created standards to be able to compare a mystery substance off of. We were tasked to investigate a murder that took place by analyzing a man’s last meal to find out where he had ate based on the content of his stomach. Before we could test the mystery substance we had to establish standards‚ so we could compare off of them. Based on the results of this lab‚ we believed that the victim last ate at Buffalo Wild Wings (Veliz). Methods and Materials We started this

Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together‚ they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction (which
