Terpenes or terpenoids are aromatic molecules not only found in cannabis but in several other plants as well. Terpene, any of a class of hydrocarbons occurring widely in plants and animals and empirically regarded as built up from isoprene, a hydrocarbon consisting of five carbon atoms attached to eight hydrogen atoms (C5H8). .

However, it was difficult for the scientist to come up with a proper definition as with carbon atom in an organic compound, inorganic compound could also come into picture. Terpenoids are widely found in plants, and can form cyclic structures such as sterols. Prerequisite: Basic knowledge of Pharmacopores and Organic Compounds. What does the word “confiscate” mean? However, if you are aware of this becoming a problem, then you will either need to be really careful with what you are using it for or just not get one. Although sometimes used interchangeably with "terpenes", terpenoids (or isoprenoids) are modified terpenes that contain additional functional groups, usually oxygen-containing. Terpenes are not just found in cannabis. Acyclic terpenes may be regarded as isomers and polymers of isoprene units; cyclic forms include menthane, bornane, and camphene. Terpenes are not just found in cannabis. Source: Whaxy.com. In 1887, German Chemist Otto Wallach introduced isoprene rule and mentioned that thermal decomposition of almost all the terpenoids produce isoprene as one of the products, and this led to suggestion that the skeleton structures of all naturally occurring terpenoids can be built up of isoprene units.

Carotenoids are a type of accessory pigment, created by plants to help them absorb light energy and convert it to chemical energy.There are two types of carotenoids, xanthophylls and carotenes, which differ only in their oxygen content.Carotenoids have a similar base structure consisting of 8 isoprene molecules.

Terpenoids: Presence or absence of terpenoids in extracts was detected by Salkowski test. Except for isoprene itself, the isoprenoids or terpenoids are dimers, trimers, tetramers or polymers in which isoprene units are usually joined in a head to tail manner: However, sometimes due to extensive metabolic modifications it is not easily possible to mark out the original 5-C units in isoprenoids. The terpenoids are presents in essential oils. Terpenes are the simple hydrocarbon molecule drive from the five-carbon isoprene structure. Technically a terpenoid contains oxygen, while a terpene is a hydrocarbon. Interestingly, maple syrup has over 300 different terpenes. However, terpenes and terpenoids are not the same. In addition, many of the structurally diverse plant terpenoids may function … But there is a tendency to use more general term terpenoids which include hydrocarbons and their Oxygenated derivatives.
