Abstract
The functional properties of haemoglobin from the Lesser Rorqual whale (Balaenoptera acutorostrata) have been characterized as a function of the heterotropic effector concentrations and temperature. The results obtained suggest the existence of sophisticated modulation mechanisms based on the interplay of organic phosphates, carbon dioxide, lactate and temperature. These, together with the very small apparent heat of oxygenation (delta H) of oxygen binding, have been physiologically interpreted on the basis of the specific metabolic needs of this diving mammal.
摘要
小须鲸（Balaenoptera acutorostrata）血红蛋白的功能特性已被表征为异向效应物浓度和温度的函数。所得结果表明，基于有机磷酸盐、二氧化碳、乳酸和温度之间的相互作用，存在复杂的调节机制。这些因素，再加上氧结合时非常小的表观氧合热（ΔH），已根据这种潜水哺乳动物的特定代谢需求进行了生理学解释。
