Cbda Synthase

CBDA synthase is the enzyme responsible for catalyzing the conversion of geranylpyrophosphol and olivetolic acid into cannabidiolic acid (CBDA), a precursor to CBD. This enzymatic pathway is fundamental to cannabinoid biosynthesis in Cannabis sativa and is controlled by the CBDAS gene. Plants expressing functional CBDA synthase produce CBDA-dominant or CBD-dominant chemotypes, commonly observed in fiber and medical-use breeding lines. The presence and activity of this enzyme directly determines whether a plant will produce significant CBD levels or redirect precursor molecules toward THC synthesis instead.

Breeders select for CBDA synthase expression when developing CBD-dominant cultivars for research, breeding stock, or hemp production. Understanding CBDA synthase activity is essential for predicting cannabinoid profiles and stabilizing desired chemotypes across generations.
