Leucoanthocyanidin
Leucoanthocyanidin (flavan-3,4-diols) are colorless chemical compounds related to anthocyanidins and anthocyanins. Leucoanthocyanins can be found in '' Anadenanthera peregrina'' and in several species of '' Nepenthes'' including '' N. burbidgeae'', '' N. muluensis'', '' N. rajah'', '' N. tentaculata'', and '' N. × alisaputrana''. Such compounds include: * Leucocyanidin * Leucodelphinidin * Leucofisetinidin * Leucomalvidin * Leucopelargonidin * Leucopeonidin * Leucorobinetinidin * Melacacidin * Teracacidin from '' Acacia obtusifolia'' and '' Acacia maidenii'' heartwoods Leucoanthocyanidins have been demonstrated to be intermediates in anthocyanidin biosynthesis in flowers of ''Matthiola incana''. Bate-smith recommended in 1954 the use of the Forestal solvent for the isolation of leuco-anthocyanins. Metabolism Leucoanthocyanidin dioxygenase uses flavan-3,4-diols to produce 3-hydroxyanthocyanidins. The gene encoding the enzyme (PpLDOX) ha ...

Glycoside
In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. Several species of ''Heliconius'' butterfly are capable of incorporating these plant compounds as a form of chemical defense against predators. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body. In formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an '' O-glycoside''), N- (a '' glycosylamine''), S-(a '' thioglycoside''), or C- (a '' C-glycoside'') glycosidic bond. Accordin ...

Ficus Bengalensis
''Ficus benghalensis'', commonly known as the banyan, banyan fig and Indian banyan, is a tree native to the Indian Subcontinent. Specimens in India are among the largest trees in the world by canopy coverage. It also known as the " strangler fig" because it starts out as epiphyte, that is, leaning on another tree that it ends up suffocating. Description ''Ficus benghalensis'' is an evergreen, fast-growing tree found mainly in monsoon and rainforests, that can reach a height of up to 30 meters. It is resistant to drought and mild frost. It produces propagating roots which grow downwards as aerial roots on the branches that grow downward like lianas. Once these roots reach the ground, they take root and become woody trunks and supportive. The figs produced by the tree are eaten by birds such as the Indian myna. Fig seeds that pass through the digestive system of birds are more likely to germinate and sprout earlier. Reproduction Banyan trees reproduce easily by seed or by sta ...

Phenol Ethers
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at ...
