A study of the platinum (II), palladium (II), and rhodium (III) chelates of aspartic and glutamic acid
<p>It is fairly well known that alpha-amino dicarboxylic acids combine quite readily with basic metal ions such as the alkaline earths. The nature of the problem includes the synthesis and characterization of six platinum metal chelates of two alpha-animo dicarboxylic acids, namely aspartic and …

Enzymology of dicarboxylic acid metabolism in Corynebacterium sp. strain 7E1C
1.Dicarboxylic acid metabolism was investigated in the alkane-utilizing bacterium Corynebacterium 7E1C.2.The best yields of dicarboxylic acid were obtained during growth on dodecane although significant amounts of tetradecanedioic acid were produced during growth on methyl myristate. No …
