MEP pathway
Produces IPP/DMAPP used to build geranyl diphosphate (GPP), the central precursor for many monoterpenes.

Terpene Atlas
Explore terpene and terpenoid chemistry without flattening cultivar names into fake precision. Cannabis occurrence is source-backed, and quantitative profiles belong to measured samples.

MVA pathway
Produces isoprenoid precursors used to form farnesyl diphosphate (FPP), the central precursor for many sesquiterpenes.
Enzymes create diversity
Terpene synthases and downstream oxidation, reduction and rearrangement create many related hydrocarbons and oxygenated terpenoids.
Pathway placement is a teaching model. Compartment exchange, downstream metabolism and compound-specific biosynthesis can be more complex.
A cultivar name is not a terpene measurement. Different samples sold or grown under the same name can produce different analytical profiles because genetics, environment, maturity, post-harvest handling, laboratory method, and naming practices vary.

Profile drivers & stability
Why terpene profiles change
A measured profile reflects biology, cultivation, post-harvest handling and analytical method together. Use these factors to interpret differences without over-assigning cause.
Measured Cannabis data
Variability across 79 inflorescences
Population statistics show how widely terpene abundance varies across Cannabis samples. These values are not cultivar-specific promises.

A “>” maximum means the reported value exceeded the source table's upper analytical boundary. High coefficients of variation are a direct warning against assigning one universal terpene percentage to a cultivar name.
Individual-profile boundary: the current source publishes aggregate statistics across 79 inflorescences, not row-level measurements. The Atlas does not reconstruct individual sample profiles from means, ranges, standard deviations, or coefficients of variation.

Mechanisms, evidence & safety
Separate research signals from proven human effects
The Atlas labels the model behind each claim and keeps preclinical receptor or animal findings separate from clinical evidence.
Research finding ≠ treatment claim.Compound co-occurrence also does not prove a clinically meaningful “entourage effect.”
Safety context
Exposure route, dose and formulation matter
Evidence model
What the Atlas will and will not claim
Primary analytical evidence
Measured material with reported analytical method, sample identity, unit, and source.
Peer-reviewed synthesis
Review evidence used to map occurrence and chemistry when primary references remain traceable.
Secondary orientation
Useful for navigation only. It is not enough by itself for a quantitative cultivar claim.
No fixed “strain percentage”
The Atlas stores cultivar labels separately from individual laboratory or publication measurements.
Evidence registry
Sources behind the Atlas
Occurrence claims are only as strong as their cited analytical or review evidence.
