Both l-amino acids and d-amino acids (d-asparagine, d-alanine (d-Ala), d-serine, d-aspartic acid, and d-proline (d-Pro)) were detected, indicating that polychaetes contain some d-amino acids. Some polychaete species exhibited notable amino acid levels, such as glycine in Capitellidae sp. and <i>Thelepus</i> sp., d-Pro in <i>Glycera</i> sp., and β-Ala in <i>Scoletoma nipponica</i> and <i>Scoletoma</i> sp.. High d-Lac levels were detected in <i>Tylorrhynchus osawai</i> and <i>Hediste diadroma</i>, (691 and 797 μmol/100 g-wet, respectively), with the d-form exceeding 98%. <i>T. osawai</i> was dominant in the upper tidal-sensitive zone, wherein other organisms were less abundant because of low salinity (3–8 PSU). Seasonal differences in the concentrations of components in <i>T. osawai</i> were observed, particularly a significant increase in d-Lac in the reproductive period. Notably, the d-Lac concentrations of <i>T. osawai</i> were higher upstream than downstream. Thus, d-Lac might be involved in strategies underlying adaptations to low salinity and reproductive activity. These results suggest that both the d-form of Lac and amino acids may play certain physiological roles in the life of polychaetes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Characterization of polychaetes inhabiting estuaries and inner bays by composition analysis of amino acids and lactate enantiomers","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-06 01:35:17.307177","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-03-04","DateCreate":"2024-03-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-024-55861-5"},"refs":null,"anarec":{"AnaID":383721,"PubliDate":2024,"Pagination":"5494","XtraPublOfAnaID":null,"ISBN":null,"Volume":"14","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
