Abiogenic Syntheses of Lipoamino Acids and Lipopeptides and their Prebiotic Significance.
Orig. Life Evol. Biosph. 45 , 427-37, (2015) Researchers have formed peptide bonds under a variety of presumed prebiotic conditions. Here it is proposed that these same conditions would have also formed amide bonds between fatty acids and amino acids, producing phosphate-free amphipathic lipoamino acids... |

Determination of ethanol using permanganate-CdS quantum dot chemiluminescence system.
Luminescence 30 , 660-7, (2015) A novel and highly sensitive chemiluminescence (CL) method for the determination of ethanol was developed based on the CdS quantum dots (QDs)-permanganate system. It was found that KMnO4 could directly oxidize CdS QDs in acidic media resulting in relatively h... |
