Terpenoids are a large and diverse class of naturally occurring organic chemicals derived from isoprene, an unsaturated five-carbon hydrocarbon. Terpenoids are produced by a wide variety of plants, insects, and marine organisms. They are often characterized by their unique smell and are used in many traditional medicines and perfumes. The classification of terpenoids is based on the number of isoprene units they contain.

Tetraterpenoids are terpenoids composed of eight isoprene units, totaling forty carbon atoms. They are a significant group of compounds with diverse biological functions and applications. The most well-known class of tetraterpenoids are the carotenoids, which are pigments responsible for the vibrant colors found in many fruits, vegetables, and flowers. Examples include beta-carotene, lycopene, and lutein. Carotenoids play crucial roles in photosynthesis as accessory pigments and also act as antioxidants, protecting cells from damage caused by free radicals. Some tetraterpenoids, like Vitamin A (retinol) and its derivatives, are essential nutrients for vision, immune function, and cell growth. Other tetraterpenoids have antimicrobial, anti-inflammatory, and even potential anti-cancer properties, making them subjects of ongoing scientific research. Their structural diversity allows for a wide range of biological activities.
