-serine has to be administered at high doses to observe clinical effects. This is thought to be due to D-serine undergoing oxidation by D-amino-acid oxidase (DAAO) before it reaches the brain. Consequently, co-administration of D-serine with a DAAO inhibitor could be a way to lower ...
Amino acids are the building blocks of protein synthesis. They are structural elements and energy sources of cells necessary for normal cell growth, differentiation and function. Amino acid metabolism disorders have been linked with a number of pathologi
A convenient and sensitive pour-plate Petri dish bioassay for the detection of siderophores containing monoprotic keto-hydroxy bidentate ligands (KHBL) has been developed. The bioassay is based on the fact that bacteria of the Proteus-Providencia-Morganella group (Proteeae) utilize various ferric ...
