    Biotransformation of Benzaldehyde into L-PAC

    Introduction L-phenylacetylcarbinol is a compound used in the synthesis of ephedrine, itself used as a precursor to amphetamines. Industrially, it is synthesized by the aerobic fermentation of benzaldehyde by baker's yeast (S. cerevisiae/SC). While the process is quite simple, it can require a...

    Biosynth: Homebrewing Ephedrine at home

    Hallo I found this tutorial on the web. it is relatively old and new procedures may be developed. it is the production of ephedrine from yeast. via L-pac reduced methilamine to ephedrine and pseudoephedrine. is there anyone who did this? possibly someone would develop TEK how to do at home...

    L-Ephedrine synthesis from L-phenylacetylcarbinol (L-PAC)

    Introduction L-Ephedrine is obtained from dried plants of various species of the genus Ephedra by initial treatment with alkali, followed by extraction with organic solvent. Extraction, purification and isolation of these drugs is time-consuming, costly and complicated by the presence of...
