Summary Introduction

To predict: The pI for pepsin proteins.

Introduction:

Isoelectric point (pI) refers to the pH at which the net charge of a molecule becomes zero or the molecule becomes electrically neutral.

Summary Introduction

To determine: The functional groups that must be present to confer this pI on pepsin.

Introduction:

Isoelectric point (pI) refers to the pH at which the net charge of a molecule becomes zero or the molecule becomes electrically neutral.

Summary Introduction

To determine: The amino acids in proteins that would contribute the functional groups.

Introduction:

Amino acids are the monomer units of proteins. These are basically organic compounds consisting of a carboxylic group (-COOH-) and an amino group (-NH2). Along with these functional groups, a side chain (R group) is also present in all the amino acids.

Please draw the structure in the box that is consistent with all the spectral data and alphabetically label all of the equivalent protons in the structure (Ha, Hb, Hc....) in order to assign all the proton NMR peaks. The integrations are computer generated and approximate the number of equivalent protons. Molecular formula: C13H1802 14 13 12 11 10 11 (ppm) Structure with assigned H peaks 2.08 3.13
A 0.10 M solution of acetic acid (CH3COOH, Ka = 1.8 x 10^-5) is titrated with a 0.0250 M solution of magnesium hydroxide (Mg(OH)2). If 10.0 mL of the acid solution is titrated with 10.0 mL of the base solution, what is the pH of the resulting solution?
