  "content_markdown": "**CBDA (cannabidiolic acid)** is the raw, unheated form of CBD that the hemp plant itself produces in the living flower. When CBDA is heated or stored for a long time, a carbon dioxide molecule is released and CBDA converts into CBD. Helsama's flower powder is CBDA-rich — [8.8% CBDA](/kunskap/nordens-klimatfordel-cbda) in the latest lab analysis.\n\n## What's the difference between CBDA and CBD?\n\nCBDA is the acid form (**C₂₂H₃₀O₄**). CBD (**C₂₁H₃₀O₂**) is only formed when CBDA loses its carboxyl group as carbon dioxide. The difference is a chemical reaction: CBDA is the plant's original form, CBD is the heated one.\n\n| Property | CBDA | CBD |\n| --- | --- | --- |\n\n| Molecular formula | C₂₂H₃₀O₄ | C₂₁H₃₀O₂ |\n\n| Form | Acid (carboxyl group) | Neutral |\n\n| Produced by plant | Yes, in the flower | No, forms with heat |\n\n## Does CBDA turn into CBD?\n\nYes, through **decarboxylation** — heat or long storage drives off the carboxyl group (CO₂) and converts CBDA into CBD.\n\n## Where does CBDA occur naturally?\n\nCBDA is found in the hemp **flower**, not in the seed. Because Helsama's flower powder is milled from the whole, unheated flower, it retains its natural CBDA — 8.8% per independent analysis (HPLC).\n\n## FAQ\n\n**Is CBDA the same as CBD?**No. CBDA is CBD's raw, acidic precursor (C₂₂H₃₀O₄). CBD (C₂₁H₃₀O₂) forms when CBDA is heated and loses carbon dioxide.\n\n**Does CBDA turn into CBD?**Yes, through decarboxylation with heat or long storage.\n\n**Do hemp seeds contain CBDA?**Barely any. CBDA is in the flower, not the seed.\n\n## Sources\n\n- PubChem: CBDA (CID 160570), CBD (CID 644019)\n\n- Helsama lab analysis (HPLC, sample ID 2450024)\n\nSee also: [CBDA and CBD: the difference between the plant's original form and the heated one](/en/kunskap/cbda-och-cbd).\n\n### Further reading\n\n- [CBDA and CBD – same origin, different expressions](/kunskap/cbda-och-cbd)\n\n- [The Nordic climate advantage: 33% more CBDA on Gotland](/kunskap/nordens-klimatfordel-cbda)\n\n- [What is hemp flower powder?](/kunskap/vad-ar-hampans-blompulver)\n\n**Continue reading:** Related questions: [CBDA and CBD – same origin, different expressions](/en/kunskap/cbda-och-cbd), [The Nordic climate advantage: 33% more CBDA on Gotland](/en/kunskap/nordens-klimatfordel-cbda) and [Vad är hampans blompulver? (och varför det inte är CBD-olja)](/en/kunskap/vad-ar-hampans-blompulver).\n\n**About Helsama’s Premium CBD Hampa:** Unheated raw hemp is the only way to buy legal full-spectrum CBD — extracted full-spectrum oils are classed as narcotics and isolate isn’t full-spectrum. Helsama’s Premium CBD Hampa is exactly that: unheated, milled raw hemp grown on Gotland, and we’re the only ones selling the CBD hemp varieties grown in Scandinavia. The Nordic summer’s long light — up to 18 hours of daylight — makes the hemp special: our third-party analyses show 8.83% CBDA versus 6.64% for the same seed grown in Italy.
