Cannabinoid Conversion

Cannabinoid conversion refers to the biochemical process by which cannabis plants synthesize and transform cannabinoid precursors into their final forms—primarily CBGA (cannabigerolic acid) converting into THCA, CBDA, or CBCA depending on enzyme expression. This process is governed by specific synthase enzymes (THCA synthase, CBDA synthase, etc.) and represents a critical point of genetic control in the plant's secondary metabolism. Breeders and researchers study conversion pathways to understand cannabinoid ratios in offspring and to predict chemotype outcomes from parent genetics. The conversion process continues throughout the plant's lifecycle and can be influenced by environmental factors like light, temperature, and harvest timing, though genetic predisposition remains the primary determinant.

Breeders working with cannabinoid ratios rely on understanding conversion enzyme inheritance patterns to reliably produce consistent chemotypes—high-THC, high-CBD, or balanced strains. Selecting parents with known synthase gene expression and tracking F1/F2 segregation helps predictably target desired cannabinoid profiles across generations.
