What are terpenes?

Terpenes belong to a large class of volatile aromatic secondary metabolites naturally produced by a diverse group of plant species

Where are terpenes produced?

Plants produce terpenes in specialized cells or resin glands. Terpenes can also be created synthetically or semi-synthetically in a laboratory using a natural molecule as the modifiable building block.

When are terpenes produced?

Plants can produce terpenes at different stages of their life cycle. Scientists can also organically synthesize terpenes on demand in a laboratory.

Why are terpenes produced?

Terpenes are classified as secondary metabolites, meaning their production is not directly involved in the growth, development or reproduction of the plant. Depending on the plant species, terpenes may assist in survival through pesticidal effects or increasing reproductive rate. Terpenes can also be naturally extracted or organically synthesized for human and animal use.

How are terpenes produced?

In nature, terpenes are derived biosynthetically from activated forms of the isoprene molecule. Terpenes are also commonly extracted from plants by various extraction methods. They can be further refined into the state of a single isolated terpene. Isolated terpenes can be organically synthesized in a laboratory setting.

What is the entourage effect?

The entourage effect describes the synergistic interaction between the phytochemicals as they exist in nature
