It is becoming increasingly apparent that magnesium deficiency (hypomagnesemia) may play an important role in chronic disease. To counteract magnesium deficiency, there is an unmet clinical need to develop new fully characterized, highly bioavailable, and substantially water-soluble magnesium supplements. To this end, triglycine (HG3), a tripeptide of the amino acid glycine, was chosen as a chelating ligand for magnesium, given its natural occurrence and water solubility, and entropically-driven metal binding. Herein, we discuss the synthesis, chemical and physical characterization, and cellular uptake of a magnesium triglycine chelate (MgG3), an octahedral complex with extraordinary water solubility and improved cellular uptake in CaCo-2 cells than select commonly used magnesium supplements.<\/jats:p>","DOI":"10.3390\/molecules26092419","type":"journal-article","created":{"date-parts":[[2021,4,21]],"date-time":"2021-04-21T21:25:10Z","timestamp":1619040310000},"page":"2419","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Synthesis and Chemical and Biological Evaluation of a Glycine Tripeptide Chelate of Magnesium"],"prefix":"10.3390","volume":"26","author":[{"given":"Derek R.","family":"Case","sequence":"first","affiliation":[{"name":"Department of Chemistry, 111 College Place, Syracuse University, Syracuse, NY 13244, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2478-7867","authenticated-orcid":false,"given":"Jon","family":"Zubieta","sequence":"additional","affiliation":[{"name":"Department of Chemistry, 111 College Place, Syracuse University, Syracuse, NY 13244, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ren","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"Balchem Corporation, 52 Sunrise Park Road, New Hampton, NY 10958, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6786-5656","authenticated-orcid":false,"given":"Robert P.","family":"Doyle","sequence":"additional","affiliation":[{"name":"Department of Chemistry, 111 College Place, Syracuse University, Syracuse, NY 13244, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jahnen-Dechent, W., and Ketteler, M.
