For discussion how dietary fats affect cardiovascular health, see Diet and heart disease.

In nutrition, monounsaturated fats are fatty acids with one double-bonded carbon in the molecule, with all of the others single-bonded carbons, in contrast to polyunsaturated fatty acids which have more than one double bond. Image File history File links This is a lossless scalable vector image. ... Look up fat in Wiktionary, the free dictionary. ... An unsaturated fat is a fat or fatty acid in which there are one or more double bonds in the fatty acid chain. ... // In nutrition, polyunsaturated fat is an abbreviation of polyunsaturated fatty acid. ... A trans fatty acid (commonly shortened to trans fat) is an unsaturated fatty acid molecule that contains a trans double bond between carbon atoms, which makes the molecule less kinked compared to cis fat. Research suggests a correlation between diets high in trans fats and diseases like atherosclerosis and coronary... -1... Omega-6 fatty acids are fatty acids where the term omega-6 signifies that the first double bond in the carbon backbone of the fatty acid, counting from the end opposite the acid group, occurs in the sixth carbon-carbon bond. ... Omega-9 fatty acids are a class of unsaturated fatty acids which have a C=C double bond in the ω-9 position. ... Saturated fat is fat that consists of triglycerides containing only saturated fatty acids. ... Interesterified fats are oils (such as soybean oil) that have been chemically modified. ... In chemistry, especially biochemistry, a fatty acid is a carboxylic acid often with a long unbranched aliphatic tail (chain), which is either saturated or unsaturated. ... Essential fatty acids, or EFAs, are fatty acids that cannot be constructed within an organism from other components (generally all references are to humans) as there are no known biochemical pathways capable of producing them. ... Diet may play an important role in causing or preventing heart disease. ... Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together. ... Covalently bonded hydrogen and carbon in a molecule of methane. ... A polyunsaturated organic compound is one in which more than one double bond exists within the representative molecule. ...

Fatty acids are long-chained molecules having a methyl group at one end and a carboxylic acid group at the other end. Fatty acid fluidity increases with increasing number of double bonds. Therefore, monounsaturated fatty acids have a melting temperature that is higher than that of polyunsaturated fatty acids, but still below that of saturated fatty acids. In chemistry, especially biochemistry, a fatty acid is a carboxylic acid often with a long unbranched aliphatic tail (chain), which is either saturated or unsaturated. ... In science, a molecule is a group of atoms in a definite arrangement held together by chemical bonds. ... In chemistry a methyl-group is a hydrophobic Alkyl functional group which is derived from methane (CH4). ... Structure of a carboxylic acid The 3D structure of the carboxyl group A space-filling model of the carboxyl group Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -C(=O)OH, usually written -COOH or -CO2H. [1] Carboxylic acids are Bronsted... The dissociation of a double-stranded DNA molecule is often referred to as melting because it occurs quickly once a certain temperature has been reached. ... Saturated fat is fat that consists of triglycerides containing only saturated fatty acids. ...

The most common monounsaturated fatty acids are palmitoleic acid (16:1 n−7) and oleic acid (18:1 n−9). Palmitoleic acid has 16 carbon atoms with the first double bond occurring 7 carbon atoms away from the methyl group. Oleic acid has 18 carbon atoms with the first double bond occurring 9 carbon atoms away from the methyl group. The illustration below shows a molecule of oleic acid. Palmitoleic acid, or (Z)-9-hexadecenoic acid, is a monounsaturated fatty acid that is a common constituent of the glycerides of human adipose tissue. ... Oleic acid is a monounsaturated omega-9 fatty acid found in various animal and vegetable sources. ...

Monounsaturated fats are found in natural foods like nuts and avocados, and are the main component of Tea-oil Camellia and olive oil (oleic acid). They can also be found in grapeseed oil, ground nut oil, peanut oil, flaxseed oil, sesame oil and corn oil. Canola oil is 57%−60% monounsaturated fat, olive oil is about 75% monounsaturated fat whilst Tea-oil Camellia is commonly over 80% monounsaturated fat.

Abel Camellia oleifera,which is originated in China, is named for being an important source of edible oil (known as tea oil or camellia oil)obtained from its seeds[1]. It is widely distributed in China as it is cultivated extensively in China. ... Olive oil is a fruit oil obtained from the olive (Olea europaea), a traditional tree crop of the Mediterranean Basin. ... Oleic acid is a monounsaturated omega-9 fatty acid found in various animal and vegetable sources. ... Grape oil (also grapeseed oil) is a vegetable oil pressed from the seeds of various varieties of Vitis vinifera grapes, an abundant by-product of wine making. ... A bottle of peanut oil Peanut oil is an organic oil derived from peanuts, noted to have the slight aroma and taste of its parent legume. ... Linseed oil is a yellowish drying oil derived from the dried ripe seeds of the flax plant (Linum usitatissimum, Linaceae). ... Sesame oil (also known as gingelly oil and til oil) is an organic oil derived from sesames, noted to have the distinctive aroma and taste of its parent seed. ... Corn oil is oil extracted from the germ of corn. ... For the figure in Celtic mythology see agriculture, canola are certain varieties of plants from which we get rapeseed oil, or the oil produced from those varieties. ... Binomial name Camellia oleifera C. Abel Camellia oleifera,which is originated in China, is named for being an important source of edible oil (known as tea oil or camellia oil)obtained from its seeds[1]. It is widely distributed in China as it is cultivated extensively in China. ...

Olive oil is a key component of the Mediterranean diet, widely regarded as being protective against cardiovascular disease while Tea-oil Camellia has been a traditional part of Asian cooking culture. Although polyunsaturated fats protect against cardiovascular disease by providing more membrane fluidity than monounsaturated fats, polyunsaturated fats are more vulnerable to lipid peroxidation (rancidity) than monounsaturated fats. On the other hand, monounsaturated fatty acids (like unsaturated fats) promote insulin resistance, whereas polyunsaturated fatty acids are protective against insulin resistance ^{[1] [2]}. The Mediterranean diet is a modern[1] nutritional model inspired by the traditional dietary patterns of some of the countries of the Mediterranean basin, particularly Greece and Southern Italy. ... Cardiovascular disease refers to the class of diseases that involve the heart and/or blood vessels (arteries and veins). ... A biological membrane or biomembrane is an enclosing or separating tissue which acts as a barrier within or around a cell. ... Lipid peroxidation refers to the oxidative degradation of lipids. ... Rancidification is the decomposition of fats and other lipids by hydrolysis and/or oxidation. ... Insulin resistance is the condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. ...

Foods containing monounsaturated fats lower LDL cholesterol, without lowering HDL cholesterol. ^[3] Low-density lipoprotein (LDL) refers to a class and range of lipoprotein particles, varying somewhat in their size and contents, which carry cholesterol in the blood and around the body, for use by various cells. ... High-density lipoproteins (HDL) form a class of lipoproteins, varying somewhat in their size (8–11 nm in diameter), that carry cholesterol from the bodys tissues to the liver. ...
