Laurie, myristic, palmitic, and stearic fatty acids make up most of the saturated fatty acids found in fats. Oleic acid, linoleic acid, and linolenic acid are the most abundant unsaturated fatty acids found in oils.

Lipase splits fatty acids from glycerol to produce free fatty acids, for example, butyric acid. If the original fat is butterfat then at low levels this produces a buttery or creamy flavour. As the free fatty acid content is increased, this strengthens the flavour to cheesy . Normally in toffees free butyric acid is not a problem at any practical level, possibly because of losses during cooking. Other free fatty acids have different flavours. Laurie acid, which is found in nuts, tastes of soap. This is not too surprising as soap often contains sodium laurate. Laurie fat sources, such as hardened palm kernel oil, are often used as a substitute for butter another potential source is nuts, which are sometimes combined with toffee. In any of these cases, lipolytic activity can shorten the shelf life of the product or render it totally unacceptable. 

Dodecanoic Laurie 42.2 Widely occurring, major acid in some seed fats, e.g., coconut oil and palm kernel oil. 

Laurie acid is a fatty carboxylic acid isolated from vegetable and animal fats or oils. For example, coconut oil and palm kernel oil both contain high proportions of lauric acid. Isolation from natural fats and oils involves hydrolysis, separation of the fatty acids, hydrogenation to convert unsaturated fatty acids to saturated acids, and finally distillation of the specific fatty acid of interest. 

CH,(OC. C3H,)CH(OOC.C3H,).CHj(OOC.C3H,), and castor oil contains glycerol esterified with ricinolek acid, Ci,H3j(OH).COOH. Laurie and myristic acids are found in coconut oil to the extent of about 45 and 15 per cent respectively. When oils or fats are heated with a solution of sodium or potassium hydroxide they are hydrolysed into glycerol and the alkali salt of the fatty acid. The sodium or potassium salts of the fatty acids are... 

Laurie (12 0) and myristic acid (14 0) occur extensively in seed fats of the Lauraceae and Myris-ticeae respectively, a fact which is reflected in the trivial names of these acids. Laurie acid, for example, is the dominant acid in cinnamon oil (80-90%), Babassu fat (40-55%, Section 3.3.2), coconut oil (41-56%, Section 3.3.8), and palmkernel oil (41-55%, Section 3.3.25). Myristic acid occurs in nutmeg butter (60-70%) and Ucuhuba oil (—70%, Section 3.3.35) and at lower levels in coconut (15-18%) and palmkernel oil (14-20%).

You are to synthesize the ethyl ester of lauric add in Experiment [8A]. Laurie acid, CH3(CH2)ioC02H (dodecanoic acid), is one of the four most common fatty acids found in naturally occurring triglycerides. It is named for the laurel botanical family from which it was first isolated in 1842. It is the most abundant of the fatty acids isolated from the vegetable oils of palm kernel oil (52%), the seed fat of Elaeis guineensis of coconut oil (48%), Cocos nucifera and of babassu oil (A6%), Attalea funifera.
