“…Using (13)C-labelled cyanobacterial cell extract as internal standard, measurement of the intracellular concentration of acyl-CoAs revealed that the reductive reaction of butanoyl-CoA to butanal is a possible rate-limiting step. In addition, improvement of the butanoyl-CoA to butanal reaction resulted in an increased rate of acetyl-CoA synthesis by possibly compensating for the limitation of free CoA species. …”

“…Moreover, of participants who reported use of concentrates based on selecting pictures of the products they had used (n = 324, 40%), 99% (n = 322) reported having seen a “wax pen or THC oil” based on a written list of product terms, whereas only 20% (n = 65) reported having seen “butane hash oil (BHO).” This suggests that asking about use of “butane hash oil” use may result in lower rates of cannabis concentrate use than asking about use of “wax pen/THC oil.” …”
