Previous studies suggested that y87 Gln in hemoglobin (Hb) F is an important site for promoting inhibition of Hb S (cy#: polymerization by H b F. We engineered and isolated the double mutant ) using a yeast expression system and characterized polymerization properties of this modified tetramer in an effort to clarify the role of Gln at position 87 in inhibiting H b S polymerization. Electrop...

In this study, we conducted a series of polymerization studies hexyl methacrylate in dimethyl sulfoxide with (0.1 - 0.4) mol dm-3 monomer and (1 10-3 – 4 10-3) benzoyl peroxide as initiators at 70 °C. Using the well-known conversion vs. time technique, effects initiator concentration on rate (Rp) were studied. An order 0.35 was obtained accordance theory divergence from normal kinetics detected...
