Organic compounds are molecules consisting of combinations of covalently-linked hydrogen, carbon, oxygen, and nitrogen atoms. Within the general subject of organic synthesis, there are many different types of synthetic routes that can be completed including total synthesis, [1] stereoselective synthesis, [2] automated synthesis, [3] and many ...
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
Piperonal can be prepared by the oxidative cleavage of isosafrole or by using a multistep sequence from catechol or 1,2-methylenedioxybenzene.Synthesis from the latter chemical is accomplished through a condensation reaction with glyoxylic acid followed by cleaving the resulting α-hydroxy acid with an oxidizing agent.
Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds , which can be used by other organisms .
Additionally, synthesis aids natural product research by helping confirm and elucidate the structures of newly isolated compounds. The field of natural product synthesis has progressed remarkably since the early 19th century, with improvements in synthetic techniques, analytical methods, and an evolving understanding of chemical reactivity.

The chalcone synthase gene of Petunia plants is famous for being the first gene in which the phenomenon of RNA interference was observed; researchers intending to upregulate the production of pigments in light pink or violet flowers introduced a transgene for chalcone synthase, expecting that both the native gene and the transgene would express ...
In the dark, plants instead release sucrose into the phloem from their starch reserves to provide energy for the plant. The Calvin cycle thus happens when light is available independent of the kind of photosynthesis ( C3 carbon fixation , C4 carbon fixation , and crassulacean acid metabolism (CAM) ); CAM plants store malic acid in their ...
Carotenoids are the precursors of important fragrance compounds in several flowers. For example, a 2010 study of ionones in Osmanthus fragrans Lour. var. aurantiacus determined its essential oil contained the highest diversity of carotenoid-derived volatiles among the flowering plants investigated.
