Chlorophyll 150-161 mucin 7, secreted Homo sapiens 131-134 12206396-6 2002 Mg2+ is the central atom of the chlorophyll molecule, and fluctuations in its levels in the chloroplast regulate the activity of key photosynthetic enzymes. Chlorophyll 32-43 mucin 7, secreted Homo sapiens 0-3 18848915-1 2008 Phytol, a C20 alcohol esterifying the C-17(3) propionate, and Mg2+ ion chelated in the central cavity, are conservative structural constituents of chlorophylls. Chlorophyll 147-159 mucin 7, secreted Homo sapiens 62-65 880298-7 1977 As calculated from corrected values of the absorbance increase of Eriochrome Blue, the light-induced internal release of Mg2+ was close to 100 nequiv per mg chlorophyll at pH 7.6 and 250 nequiv at pH 7.1. Chlorophyll 157-168 mucin 7, secreted Homo sapiens 121-124 11816-2 1976 In a NaCl and KCl medium, the light-dependent decrease in the Mg2+ content of the thylakoid membranes at pH 8.0 is found to be 23 nmol Mg2+ per mg chlorophyll, whereas in a sorbitol medium it is 83 nmol Mg2+ per mg chlorophyll.
