Question
Chapter 2, Problem 3P
Interpretation Introduction
Interpretation:
The given amino acids should be matched to the appropriate given side chain type.
Concept introduction:
Amino acids are so named because they all are weak acids. All amino acids have at least two dissociable hydrogens, (diprotic), and some have three dissociable hydrogens and are triprotic.

- . Separating Glycated Hb From Normal Hb (Integrates with Chapters 5and 6.) Human hemoglobin can react with sugars in the blood(usually glucose) to form covalent adducts. The a-amino groups ofN-terminal valine in the Hb b-subunits react with the C-1 (aldehyde)carbons of monosaccharides to form aldimine adducts, whichrearrange to form very stable ketoamine products. Quantitation ofthis “glycated hemoglobin” is important clinically, especially fordiabetic individuals. Suggest at least three methods by which glycatedHb (also referred to as HbA1c) could be separated from normal Hband quantitatedarrow_forwardMore ratios.

- Peptides. 1. Draw the peptide Ala-Glu-Gly-Lys, as it would occur at physiological pH = 7.4. The R groups of Ala and Gly are not acidic or basic, therefore do not have a pka and the charge on these R groups is therefore independent of pH. Glu is acidic and Lys is basic, therefore the charge on these amino acids is pH dependent. The pKas are shown below. pKa N-term = 9.0 C-term = 3.5 Glu4.1 Lys = 10.5 2.

- Draw the structure. Saccharide X occurs in the roots of several species of plants. Deduce the structure of saccharide x from the following data: 1. Acidic hydrolysis of 1 mol of stachyose yields 2 mol of D-galactose, 1 mol of D-glucose, and 1 mol of D-fructose. 2. Stachyose is a nonreducing sugar. 3. Treating stachyose with an a-galactosidase produces a mixture containing D-galactose, sucrose, and a nonreducing trisaccharide called raffinose. 4. Acidic hydrolysis of raffinose gives D-glucose, D-fructose, and D-galactose. Treating raffinose with an a-galactosidase yields D-galactose and sucrose. Treating raffinose with invertase (an enzyme that hydrolyzes sucrose) yields fructose and melibiose 5. Methylation of saccharide x followed by hydrolysis yields 2,3,4,6-tetra-O-methyl-D-galactose, 2,3,4-tri-0-methyl-D-galactose, 2,3,4-tri-O-methyl-D-glucose, and 1,3,4,6-tetra-O-methyl-D-fructose.arrow_forwardPlease help me with this question.
