CBG
CBG is short for cannabigerol, often introduced in textbooks as a minor cannabinoid on finished flower even though pathway diagrams place related acid forms early in cannabinoid assembly talk. Chemists group CBG with the cannabigerol family: an open structure that educational charts treat as a parent-neighbor to several later headline names. Menus still print CBG as its own line when the lab measures it, rather than treating the word as a brand badge or a cultivar family.
Catalog primers sometimes say other cannabinoids are discussed as coming from CBGA-related routes. That is pathway language, not a promise that every jar will show high CBG. Neutral CBG on a retail panel is simply the measured cannabigerol entry for that sample. Educational pages separate that chemistry vocabulary from strain-family marketing language so readers can learn the name without mistaking it for a pedigree.
Compare THC and THCA for the main intoxicating pair, and CBD with CBDA for the major non-THC pair. CBN belongs more to aged-material vocabulary. CBC is another minor line in the chromene-style grouping. THCV is a varin relative of THC. None of those names replace CBG on a careful menu, and CBG does not replace them either.
CBG is easy to over-read as a rare specialty brand word. In education it is a structure-and-catalog topic: how chemists name it, how panels list it, and how it sits beside better-known neighbors without becoming a product claim. Amounts remain sample-specific wherever a real certificate exists, so this page never invents a typical percentage.

CBG binds CB1 and CB2 only weakly. A CBG line on a lab sheet is a measured name, not a receptor result.
