Linoleic acid (LA) is an organic compound with the formula HOOC (CH2)7CH=CHCH2CH=CH (CH2)4CH3. Both alkene groups (−CH=CH−) are cis. 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. [5] Linoleic acid is a polyunsaturated, omega−6 fatty acid.
Identify the number of carbon atoms in stearic acid and use zigzag lines to represent each carbon-carbon bond in the chain, adding a carboxylic acid group at the end.
Write a balanced equation for the complete combustion of linoleic acid (C 18 H 32 O 2), a polyunsaturated omega-6 fatty acid found in olive oil. Assume that the water produced is in the liquid phase. Calculate the standard enthalpy of combustion in kJ/mol and the caloric content of linoleic acid in cal/g. ΔH f (C 18 H 32 O 2 (l)) = −634.7 kJ/mol
Short Answer. Expert verified. Linoleic acid is an unsaturated fatty acid with 18 carbons that can be found in a variety of vegetable oils, including sunflower and poppy seed oil. Step by step solution. 01. Introduction. Lipids are hydrophobic esters of intermediate to long-chain fatty acids.
22 Μαρ 2021 · The body uses linoleic acid to synthesize many of the other unsaturated fatty acids, such as arachidonic acid, a precursor for the synthesis of prostaglandins. In addition, the essential fatty acids are necessary for the efficient transport and metabolism of cholesterol.
Carboxylic Acids and Esters 1. Alcohols can be used to prepare organic compounds with different functional groups. HO(CH 2) 4 OH can be oxidised to form HOOC(CH 2) 2 COOH. i. State the reagents and conditions and write an equation for this oxidation. In the equation, use [O] for the oxidising agent.
Since the first carbon in a double bond is carbon 9, oleic acid is an omega-9 fatty acid. (C) This is linoleic acid. To simplify larger molecules scientists often use line-angle drawings....
