32612224-5	2020	Here we show, using atomic-scale quantitative imaging and correlative spectroscopies, that the nanoscale crystallites of hydroxylapatite (Ca5(PO4)3(OH)), which are the fundamental building blocks of enamel, comprise two nanometric layers enriched in magnesium flanking a core rich in sodium, fluoride and carbonate ions; this sandwich core is surrounded by a shell with lower concentration of substitutional defects.	Magnesium	250-259	carbonic anhydrase 5A	Homo sapiens	138-147	
26004220-4	2015	For instance, Mg(2+) and Zn(2+) favor the substitution at the Ca-5 site of beta-TCP while Sr(2+) and Ba(2+) tend to occupy Ca-3 and Ca-4 in the beta-type crystal structure.	Magnesium	14-16	carbonic anhydrase 5A	Homo sapiens	62-66
