Abstract
Information is presented on various aspects of carotenoid biosynthesis in higher plants. These include the pathways of conversion of acetyl CoA to isopentenyl pyrophosphate, the formation of phytoene and, from the latter compound, the conversion of phytoene to lycopene and cylcic carotenes and the modifications of acyclic and cyclic carotenes to yield alicyclic xanthophylls, epoxycarotenoids, cyclopentenyl ketones, allenic and acetylenic carotenoids, and methyl‐oxidized carotenoids. Other subjects covered in this review are the stereochemistry and mechanism of synthesis for various carotenoids. Insofar as possible, information on the enzymes that catalyze the synthesis of carotenes is given. This includes their separation from other proteins, the products of their action, and the properties of each. Emphasis in this review is placed upon the newer findings on carotenoid biosynthesis and their significance. Some emphasis is also placed upon unsolved problems.Keywords
