The O<sub>2</sub> and CO<sub>2</sub> combining properties of <i>Palaemon adspersus</i> hemolymph is studied, aiming to assess respiratory function and the environmental and metabolic adaptations of hemocyanin of natant decapods where, in contrast to the intensively-studied, larger and predominantly less active reptant decapods, virtually no information is available.  2.  The hemolymph shows a high O<sub>2</sub> carrying capacity (mean=2.8 vol%), a low O<sub>2</sub> affinity (at 15 °C half-saturation tension,P 50=16 and 37 mm Hg at pH 7.85 and 7.65, respectively), pronounced cooperativity in O<sub>2</sub> binding (Hill''s coefficient,n2.8) and a large, pH dependent Bohr factor (=logP 50/pH=-2.0 and -0.9 at pH 7.85 and 7.4, respectively) (Figs. 1 and 2). These qualities are distinct from those typifying reptant hemocyanins and appear illsuited for O<sub>2</sub> transport at low ambient tensions, but well-adapted for O<sub>2</sub> delivery in tissues at high P <sub>O 2</sub>, supporting high levels of metabolism and activity.  3.  CO<sub>2</sub> has a specific, augmenting effect on O<sub>2</sub> affinity at high pH (Fig. 3), indicating carbamate formation with an opposite oxygenation-linkage as in vertebrate hemoglobins. Astrup titrations indicate the presence of a small but distinct Haldane effect at physiological pH, and buffering capacity varies greatly (HCO<sub>3</sub>/pH-4.4 to -9.3 mmol·1-1<sup>-1</sup>·(pH unit)1 depending on hemocyanin concentration) (Fig. 4). Equilibrium curves of total, non-protein-bound CO<sub>2</sub> show large capacitance for transport at low, in vivo CO<sub>2</sub> tensions (Fig. 4).  4.  The data are discussed comparatively, particularly as regards hemocyanin function in reptant decapods, and the O<sub>2</sub>, CO<sub>2</sub> and proton exchanges involved.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Oxygen and carbon dioxide transporting qualities of hemocyanin in the hemolymph of a natant decapod <i>Palaemon adspersus</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:31:00.883317","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1981,"MonPub":null,"DateUpdate":"2009-05-18","DateCreate":"2009-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1981MW60000003","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/BF00782589"},"refs":null,"anarec":{"AnaID":135744,"PubliDate":1981,"Pagination":"21-27","XtraPublOfAnaID":null,"ISBN":null,"Volume":"145","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43222,"SerRR":"Journal of comparative physiology.
