Hydnocarpic Acid
Hydnocarpic acid is an unsaturated fatty acid. It differs from most fatty acids by having a cyclic ring system at the terminus, rather than being entirely straight chain. It is found in the oil from plants of the genus '' Hydnocarpus'' from which it derives its name. See also * Chaulmoogric acid Chaulmoogric acid is a fatty acid found chaulmoogra oil, the oil from the seeds of ''Hydnocarpus wightianus''. It is an unusual fatty acid which has a cyclopentene ring at its terminus instead of being entirely linear like most fatty acids. It ... References {{reflist Fatty acids Cyclopentenes ...

Unsaturated Fatty Acid
In chemistry, in particular in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells. History The concept of fatty acid (''acide gras'') was introduced in 1813 by Michel Eugène Chevreul, though he initially used some variant terms: ''graisse acide'' and ''acide huileux'' ("acid fat" and "oily acid"). Types of fatty acids Fatty acids are classified in many ways: by length, by saturation vs unsatura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclic Compound
A cyclic compound (or ring compound) is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring. Rings may vary in size from three to many atoms, and include examples where all the atoms are carbon (i.e., are carbocycles), none of the atoms are carbon (inorganic cyclic compounds), or where both carbon and non-carbon atoms are present ( heterocyclic compounds with rings containing both carbon and non-carbon). Depending on the ring size, the bond order of the individual links between ring atoms, and their arrangements within the rings, carbocyclic and heterocyclic compounds may be aromatic or non-aromatic; in the latter case, they may vary from being fully saturated to having varying numbers of multiple bonds between the ring atoms. Because of the tremendous diversity allowed, in combination, by the valences of common atoms and their ability to form rings, the number of possible cyclic structures, even of ...

Hydnocarpus
''Hydnocarpus'' is a genus of medium to large trees in the family Achariaceae; the genus was previously placed in the now defunct family Flacourtiaceae. Species have been recorded from Indochina, Indonesia, Malaysia and the Philippines. Characteristics ''Hydnocarpus'' has alternate leaves, small dioecious racemose flowers, and capsules of which several are sources of chaulmoogra oil and hydnocarpus oil. A species of ''Hydnocarpus'' is thought to host to the Peacock mite '' Tuckerella filipina''. Species ''Plants of the World Online'' currently includes: * '' Hydnocarpus alcalae'' C.DC. * '' Hydnocarpus alpinus'' Wight (''H.alpina'') * '' Hydnocarpus annamensis'' Lescot & Sleumer ex Harwood & B.L.Webber * '' Hydnocarpus annamicus'' H.L.Li * '' Hydnocarpus anomalus'' (Merr.)

Chaulmoogric Acid
Chaulmoogric acid is a fatty acid found chaulmoogra oil, the oil from the seeds of ''Hydnocarpus wightianus''. It is an unusual fatty acid which has a cyclopentene ring at its terminus instead of being entirely linear like most fatty acids. It is a white crystalline solid with a melting point of 68.5 °C. It is soluble in ether, chloroform, and ethyl acetate. In the early 20th century, it was investigated as a possible treatment for leprosy Leprosy, also known as Hansen's disease (HD), is a Chronic condition, long-term infection by the bacteria ''Mycobacterium leprae'' or ''Mycobacterium lepromatosis''. Infection can lead to damage of the Peripheral nervous system, nerves, respir ... due to the use in traditional medicine of chaulmoogra oil for leprosy.
