Normal hemoglobin is designated HbA. Under conditions of low [O₂], HbS aggregates and distorts the red blood cell into a sickle shape. See image of eight aggregated HbS molecules. Sickled red blood cells are relatively inflexible and may clog capillary beds, causing pain and tissue damage. The sickled red blood cells also have a shorter life span, leading to anemia. Which amino acids would be expected to produce a similar sickling effect if substituted for Val at position 6? arginine phenylalanine Aggregate of HbS molecules lysine leucine alanine Sickling occurs in deoxyhemoglobin S but not in oxyhemoglobin S.

Enz-SH + Ag+ → Enz–S-Ag + H* The affinity of Ag* for sulfhydryl groups is so great that Ag* can be used to titrate –SH groups quantitatively. To 10.0 mL of a solution containing 1.2 mg/mL of a pure enzyme, an investigator added just enough A£NO, to completely inactivate the enzyme. A total of 0.346 µmol AgNO, was required. Calculate the minimum molecular weight (M,) of the enzyme. minimum M, = The determined M, is not exact, but it is a minimum value for the M, of the enzyme. Why does the M, value obtained this way give only the minimum molecular weight? The Ag* would also react with the terminal carboxyl group. There is only one polypeptide chain. There are no disulfide bonds in the protein. O There is only one titratable –SH group per protein molecule.arrow_forward

The pI is the pH at which the substance has a charge of zero. It affects how the amino acid moves in gels of different pH values during electrophoresis.arrow_forward
