Cyclic forms of D-glucose: Haworth formulaThe furanose and pyranose forms of D-glucose can be presented using Haworth formula. The followingtemplates are used for this formula. Note the numbering of the carbon atoms and the anomeric carbon(this carbon defines the alpha and beta isomer).Furanose template (furan)Pyranose template (pyran)anomeric carbonanomeric carbonCompare the Fisher and Haworth formula of D-glucofuranose and D-glucopyranose. Notice that thegroups attached to C-1, C-2, and C-3 on the left side of the Fisher formula are written above the planeof the furanose template.Fisher formulaHaworth formulaH FOHH-2HOH,č 5-OHFOH-HHO-3H4онH1H-4H-5HOH36 CH2OHHOHAlpha-D-glucofuranoseAlpha-D-glucofuranoseHOH2C-онOHноHFOH-OHНоHH.OHHČH2OHBeta-D-glucofuranoseBeta-D-glucofuranose

Consider histidine as a free amino acid in aqueous solution. a) Draw the most likely structure of histidine under biochemical standard state conditions. Given that free histidine has the following three pKa values, assign each to its corresponding acidic hydrogen or conjugate base in the structure. pKa1 = 1.7; pKa2 = 6.2; and pKa3 = 9.1 b) For each pKa, give the corresponding expression for the equilibrium constant.

Hemoglobin is considered to be a tetrameric complex with a 64 kDa (α β)2. When attempting to purify hemoglobin, we must first purify the α and β monomers (about 16 kDa each) to prepare the tetramer. This is formed from the dimer intermediate: 2 α + 2 β -> 2 αβ -> (α β)2.
