Terpenoids, also known as isoprenoids, are a large and diverse class of organic chemicals that are produced by a variety of plants, particularly conifers. They are derived from five-carbon isoprene units and are often classified based on the number of these units they contain. Terpenoids play crucial roles in plant physiology, including serving as phytohormones, acting as agents of plant defense, and attracting pollinators.

The basic building block of terpenoids is isoprene (2-methyl-1,3-butadiene), and they are classified into different groups based on the number of isoprene units they contain. Hemiterpenoids contain one isoprene unit, monoterpenoids contain two, sesquiterpenoids contain three, diterpenoids contain four, sesterterpenoids contain five, triterpenoids contain six, and tetraterpenoids contain eight isoprene units. Polyterpenoids contain more than eight isoprene units.

Terpenoids are known for their diverse biological activities and have been used in traditional medicine for centuries. Many terpenoids have been shown to have anti-inflammatory, antioxidant, and anticancer properties. They are also used in the fragrance and flavor industries due to their pleasant aromas and tastes. Examples of well-known terpenoids include limonene, found in citrus fruits, and menthol, found in mint.

The biosynthesis of terpenoids involves the condensation of isoprene units, which are derived from either the mevalonate pathway or the methylerythritol phosphate pathway. The specific enzymes involved in these pathways determine the diversity of terpenoid structures. The study of terpenoids continues to be an active area of research due to their potential applications in medicine, agriculture, and industry.
