All investigations were performed in aqueous solution. The overall stability constants of the complexes and non-covalent compounds were obtained using the potentiometric method with computer calculation of the data. Moreover, equilibrium constants of the reaction were determined. The mode of coordination was obtained using spectroscopic methods. Analysis of the potentiometric and spectroscopic data confirmed the involvement and effectiveness of phosphate groups in species formation as well as the influence of pH on the mode of coordination of the investigated biomaterials. In the next step, studied complexes will be applied as potential biomaterials with biological applications.<\/jats:p>","DOI":"10.3390\/ma14154309","type":"journal-article","created":{"date-parts":[[2021,8,1]],"date-time":"2021-08-01T21:44:32Z","timestamp":1627854272000},"page":"4309","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Influence of pH on Complexation Process of Copper(II) Phosphoethanolamine to Pyrimidine Nucleosides"],"prefix":"10.3390","volume":"14","author":[{"given":"Malwina","family":"Gabryel-Skrodzka","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University in Poznan, Uniwersytetu Poznanskiego 8, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martyna","family":"Nowak","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University in Poznan, Uniwersytetu Poznanskiego 8, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaudia","family":"Stachowiak","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University in Poznan, Uniwersytetu Poznanskiego 8, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0591-9409","authenticated-orcid":false,"given":"Michal","family":"Zabiszak","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University in Poznan, Uniwersytetu Poznanskiego 8, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1691-7302","authenticated-orcid":false,"given":"Kazuma","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Pharmaceutical Sciences Department, Kanazawa University, Kakuma-machi, Kanazawa 920-1192, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7989-5083","authenticated-orcid":false,"given":"Renata","family":"Jastrzab","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University in Poznan, Uniwersytetu Poznanskiego 8, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"127","DOI":"10.1038\/ncb0502-e127","article-title":"The origins of protein phosphorylation","volume":"4","author":"Cohen","year":"2002","journal-title":"Nat.
