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
Introduction to Linoleic Acid. Linoleic acid is a polyunsaturated omega-6 fatty acid, one of the many different types of fatty acids critical to various bodily functions. It’s represented by the molecular formula C 18 H 32 O 2.
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.
12 Ιαν 2012 · Experiment 12 –Lipids. Lipids are a class of biological molecules that are insoluble in water and soluble in nonpolar solvents. There are many different categories of lipids and each category has different components present in its structure. Fatty acids are components of many types of lipids.
Linoleic Acid (also called cis, cis,-9,12-octadecadienoic acid) is an example of a poly-unsaturated fatty acid, due to the presence of two C=C double bonds. It is the main fatty acid found in vegetable oils such as soybean oil, corn oil and rapeseed oil.
