We exploited differences in the acid lability of amide bonds within high-molecular-weight (HMW) DON to show that vertical DON profiles result in part from the presence of two chemically distinct pools of amide. Half of HMWDON in surface waters is present as N-acetyl amino polysaccharides. In contrast, nearly all deep-sea HMWDON, and therefore, most HMWDON, is present in amides that resist both chemical hydrolysis and biological degradation.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Two chemically distinct pools of organic nitrogen accumulate in the ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2005-06-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000229190700042","VABBcode":null,"OpenAcc":0,"DOI":"10.1126/science.1108925"},"refs":null,"anarec":{"AnaID":73101,"PubliDate":2005,"Pagination":"1007-1010","XtraPublOfAnaID":null,"ISBN":null,"Volume":"308","Issue":"5724","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43776,"SerRR":"Science (Washington).
