Catalpic Acid

	Catalpic Acid Catalpic acid is a conjugated polyunsaturated fatty acid. The melting point of this fatty acid is 32 °C. Catalpic acid occurs naturally in the seeds of yellow catalpa (''Catalpa ovata'') and southern catalpa ''Catalpa bignonioides'' is a species of ''Catalpa'' that is native to the southeastern United States in Alabama, Florida, Georgia, Louisiana, and Mississippi. Common names include southern catalpa, cigartree, and Indian-bean-tree (or Indian bean ... (''Catalpa bignonioides''). Seeds of ''Catalpa'' species contain about 40% catalpic acid.Gunstone, F.D. et al. (2007). The Lipid Handbook with CD-ROM, Boca Raton: CRC Press.

picture info	Conjugated Polyunsaturated Fatty Acid Conjugated fatty acids is jargon for polyunsaturated fatty acids containing at least one pair of conjugated double bonds. An example of a conjugated fatty acid is the rumenic acid, found in the meat and milk of ruminants. Most unsaturated fatty acids that are doubly unsaturated do not feature conjugation, e.g., linoleic acid and linoelaidic acid. Some conjugated fatty acids may confer health benefits ranging from the prevention of hypertension to protection against certain forms of cancer, although more research is needed to confirm such effects. Clinical studies and animal models have shown that conjugated fatty acids confer physiological benefits such as the regulation of the synthesis and breakdown of lipids, reduction of inflammation, and antioxidant properties. Conjugated fatty acids include isomers of linoleic acid. Conjugated analogues linoleic acids are the most investigated conjugated fatty acids. The reason why the isomer of conjugated fatty acids are studied is because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Yellow Catalpa ''Catalpa ovata'', the yellow catalpa or Chinese catalpa (), is a pod-bearing tree native to China. Compared to ''C. speciosa'', it is much smaller, typically reaching heights between . The inflorescences form bunches of creamy white flowers with distinctly yellow tinging; individual flowers are about wide. They bloom in July and August. The leaves are very similar in shape to those of ''Paulownia tomentosa'', having three lobes (two are abruptly truncated on either edge, with a third, central, slightly acute, pointed lobe forming the leaf apex), and are darkly green. Fruits are very narrow, foot-long pods. Although native to the more temperate provinces within China (Anhui, Gansu, Hebei, Heilongjiang, Henan, Hubei, Jiangsu, Jilin, Liaoning, Nei Monggol, Ningxia, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, Xinjiang), ''C. ovata'' is also cultivated in North America and Europe, and has become a parent of ''Catalpa × erubescens'' with the American species ''Catalpa bignonioide ...

picture info	Southern Catalpa ''Catalpa bignonioides'' is a species of ''Catalpa'' that is native to the southeastern United States in Alabama, Florida, Georgia, Louisiana, and Mississippi. Common names include southern catalpa, cigartree, and Indian-bean-tree (or Indian bean tree). It is commonly used as a garden and street tree. Description It is a medium-sized deciduous tree growing to tall, with a trunk up to diameter, with brown to gray bark, maturing into hard plates or ridges. The short thick trunk supports long and straggling branches which form a broad and irregular head. The roots are fibrous and branches are brittle, its juices are watery and bitter tasting. The leaves are large, bright green and heart shaped, being long and broad. They appear late, and as they are full-grown before the flower clusters open, they add much to the beauty of the blossoming tree. They secrete nectar, a most unusual characteristic for leaves, by means of groups of tiny glands in the axils of the primary veins. ...

picture info	Fatty Acids In chemistry, particularly 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]
