Structure of linoleic acid

Alpha Linolenic Acid (ALA) is an 18-carbon polyunsaturated fatty acid with three double bonds. It is also called an omega-3 fatty acid, and is essential for all mammals It is a fatty acid sometimes denoted 18:2 (n-6) or 18:2 cis -9,12. A linoleate is a salt or ester of this acid. Linoleic acid is a polyunsaturated omega-6 fatty acid. It is a colorless or white oil that is virtually insoluble in water but soluble in many organic solvents Overview of Structure Of Linoleic Acid A polyunsaturated omega-VI fatty acid, which is an essential fatty acid for a human body is termed as Linoleic acid. This essential fatty acid must be obtained through the proper form of diet. It is white or colorless oil which is always insoluble with water Linoleic acid is an organic compound with the formula COOH(CH2)7CH=CHCH2CH=CH(CH2)4CH3. Both alkene groups are cis. It is a fatty acid sometimes denoted 18:2 or 18:2 cis-9,12. A linoleate is a salt or ester of this acid. Linoleic acid is a polyunsaturated omega-6 fatty acid. It is a colorless or white oil that is virtually insoluble in water but soluble in many organic solvents. It typically occurs in nature as a triglyceride rather than as a free fatty acid. It is one of two essential fatty ac

The fatty acids _ linoleic and linolenic acid cannot be synthesized by humans . In a strict sense, only these two are essential fatty acids. Structure of linolenic acid : [ CH3CH2CH = CHCH2CH = CHCH2CH = CH(CH2)7 COOH ] Structure of linoleic acid. Linoleic acid or LA (18 carbon atoms), from the Latin linon, meaning flax, plus oleic, meaning oil or olive oil, was isolated by Sacc F. in 1844 from linseed oil. The exact structure was clarified by Hilditch T.P. et al. in 1939, and was synthesized by Raphael R.A. and Sondheimer F. in 1950. It is a polyunsaturated fatty acid (PUFA) with two cis.

The word linolenic is an irregular derivation from linoleic, which itself is derived from the Greek word linon (). Oleic means of or relating to oleic acid because saturating linoleic acid's omega-6 double bond produces oleic acid.. Dietary sources.

The units of the fatty acids in this equation were percent of energy intake, so that a 10% increase in energy consumed as linoleic acid would correspond to a 13 mg/dL decrease in blood cholesterol. The measurements were in terms of total blood cholesterol, since LDL and HDL cholesterol were not yet routinely measured The structures of two of the major triunsaturated acids-linolenic acid and-linolenic acidare given in Table 1.3. Their full names are 6c,9c,12c-octadecatrienoic acid and 9c,12c,15c-octadecatrienoic acid respectively. The name derived as above from octadeca with the trienoicadded shows that there are three ethylenic double bonds The behaviour of Langmuir monolayers corresponding to unsaturated fatty acids belonging to the omega-9 (oleic acid), omega-3 (α-linolenic and stearidonic acids) and omega-6 (linoleic, γ-linolenic and eicosadienoic acids) series was studied in order to get insight into the influence of various factors (such as subphase temperature, length, degree of unsaturation and position of the double bonds in the aliphatic chains) on the molecular conformation of these fatty acids spread at the A/W.

The molecular structure of common CLA and CLnA that of bioactive properties are summarized in Fig. 1.CLA were first isolated from ground beef by Pariza in 1983 .Considering positional and geometrical isomers, there are possibly 54 CLA isomers , but attributing to the selectivity of enzymes, only about 20 of them have been identified in nature .The c9, t11-CLA, also known as rumenic acid, is. Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils.It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9.It has the formula CH 3 (CH 2) 7 CH=CH(CH 2) 7 COOH. The name derives from the Latin word. Linoleic acid hydrogenation was performed in a three-phase 300 ml steel Parr autoclave. The reactor was equipped with a cooling coil and a 5 μm filtered reactor inlet line, which avoided the pass of the catalyst particles through it. A stirring rate of 1500 rpm was used in the experiments. A bubbling and preheating unit was installed upstream the reactor in order to feed the reactant solution Punicic acid is synthesized in situ from linoleic acid, an unconjugated octadecadienoic fatty acid present in about 7% of the oil (Lansky & Newman, 2007). Chemical structures of punicic acid (C18: 3-9cis, 11trans, 13cis) and α-eleostearic are shown in Fig. 1 Linoleic acid belongs to one of the two classes of essential fatty acids that humans require. These acids are called essential because they can not be synthesised by the human body and must be eaten in food. If a person does not eat sufficient amounts of these essental fatty acid (i.e. at least a tablespoon day), they may start to suffer.
