A study of the subunit structure of the extracellular hemoglobin of Lumbricus terrestris.
The dissociation of the extracellular hemoglobin of the earthworm Lumbricus terrestris was investigated. At neutral pH, its sz00,~ = 58.9 f 0.2 S and D:o,w = 1.61 f 0.05 X 1O-7 cm2 s-l corresponded to a molecular weight of 3.23 f 0.18 x 106. A minimum molecular weight of 24,000 per heme group was determined from the iron and heme contents, 0.221 f 0.011 weight % and 2.78 =k 0.14 weight %, respe...
متن کاملThe extracellular hemoglobin of the earthworm, Lumbricus terrestris. Determination of subunit stoichiometry.
The giant extracellular hemoglobin of the earthworm, Lumbricus terrestris, has four major O2-binding chains, a, b, and c (forming a disulfide-linked trimer) and d ("monomer"). Participation of additional "linker" chains L1, L2, and L3 is necessary for the assembly of the approximately 3,900+ kDa two-tiered hexagonal structure. We have determined the proportions of linker chains, trimer, and cha...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
