The O<sub>2</sub> affinity of Hb in whole coelomic fluid is moderately high (<i>P</i><sub>50</sub> ± 7 mm). The O<sub>2</sub> equilibrium curve is slightly sigmoid (n=1.4 to 1.8). Variation in pH effects neither P<sub>50</sub> (no Bohr effect) nor n, and the temp sensitivity of O<sub>2</sub>-binding indicates an apparent heat of oxygenation (Delta H) of approx. or equal to -13 kcal/mole. At acid pH added ATP decreases the O<sub>2</sub>-affinity analogous to the influence of organic phosphates in vertebrates, but this effect is slight and its functional significance is questionable. <i>Glycera</i> red cells appear to contain tetrameric as well as monomeric Hb. On the basis of iso-electric point the Hb resolves into numerous components. Four main components isolated preparatively show marked differentiation in oxygen affinity. The results are discussed in relation to the burrowing habitat and compared with available data on Hb from the American <i>G. dibranchiata</i> and the high molecular annelid Hbs.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Functional and molecular properties of corpuscular haemoglobin from the bloodworm <i>Glycera gigantea</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:31:28.144158","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1973,"MonPub":null,"DateUpdate":"2021-02-18","DateCreate":"2002-10-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0077-7579(73)90054-9"},"refs":null,"anarec":{"AnaID":28571,"PubliDate":1973,"Pagination":"316-327","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
