Carbon monoxide (CO) is an indispensable C1 building block. For decades this abundant gas has been employed in hydroformylation and Pausen-Khand catalysis, amongst many related chemistries, where a single, non-coupled CO fragment is delivered to an organ
function, according toMount Sinai. It isn't the fatty acid itself that has caused alarm, but rather how it is made. Horizon Organic produces its DHA Omega-3 through an industrial brewing technique involving algae, a process some people believe should not form part of an organic milk product...
