These compounds share a common motif – a carbonyl function conjugated to a carbon-carbon double bond (alkene) in the alpha, beta position (i.e. a general structure of R-C(=O)-CR’=CR’'R'''). The electron attracting and delocalizing activity of the carbonyl function results in an el...
The NOAA/ESRL lidar operations were funded by the NOAA Climate Program Office, Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program and the NASA-sponsored Tropospheric Ozone Lidar Network (NNL13AA08I) (TOLNet, http://www-air.larc.nasa.gov/missions/TOLNet/). TOLNet also supported ...
ALA is an 8-carbon sulfur containing fatty acid that has the International Union of Pure and Applied Chemistry name of 5-([3R]-dithiolan-3-yl) pentanoic acid, and is also known as thioctic acid, ALA, and lipoate. It is synthesized de novo from octanoic acid by lipoic acid synthase in...
