Problem 16.48 (a) Write a formula for a fat (found in butter) of butanoic acid. (6) Alkaline hydrolysis of a fat of a high-molecular-weight acid gives a carboxylate salt (a soap). Write the equation for the reactions of the fat of palmitic acid, n-C,3H, COOH, with aqueous NaOH. ... 

The simplest or lowest member of the fatly acid series is formic acid, HCOOH. followed by acetic acid, CHiCOOH. propionic acid with three carbons, butyric acid with four carbons, valeric acid with five carbons, and upward to palmitic acid with sixteen carbons, stearic acid with eighteen carbons and melissic acid with thirty carbons. Fatty acids are considered to be the oxidation product of saturated primary alcohols. These acids are stable, being very difficult [with the exception of formic acid) to convert to simpler compounds they easily undergo double decomposition because of the carboxyl group they combine with alcohols to form esters and water they yield halogen-subslitulion products they convert to acid chlorides when reacted with phosphorus pcntachloridc and Iheir acidic qualities decrease as their formula weight increases.

The specimens were treated according to the method of Nakagami and coworkers [17,18]. Japanese linden Tilia japonica Smik.) was treated with trifluoroacetic acid anhydride and the fatty acids (TFAA method), which included acetic acid, propionic acid, valeric acid, hexanoic acid, decanoic acid, lauric acid, and palmitic acid. Dynamic measurements were made with a torsion pendulum apparatus under a vacuum. An increasing temperature rate was 2°C/min. The amount of introduced side chain per gram of wood is about 4-6 mmol/g [16]. The chemical structure of the treated wood is presented by the formula ... 

Another product manufactured by Loders-Croklaan (Unilever) and named Beta-pol consists mainly of triacylglycerols of the type UPU. This is used as a constituent of infant formulas (191). Human milkfat is unusual in that it contains a significant proportion of its palmitic acid in the sn-2 position. Although this is true also for lard (pig fat), it is not a feature of vegetable oils. Betapol is made from tripalmitin and oleic acid using the lipase from Mucor miehei to promote 1,3-acyl exchange. These materials are expensive, and in practice, fractionated palm oil, rich in tripahnitin, is reacted with acids from high-oleic sunflower or safflower or from olive oil. 

Betapol , a human milkfat substitute produced by Loders Croklaan (Wormerveer, the Netherlands), is produced by interesterification of vegetable oils in which the component TAGs have been modified to more closely resemble those found in breast milk. This product closely mimics the specific structure and fatty acid composition of human milkfat and resembles breast milk in terms of its nutritional value and high content of palmitic acid at the sn-2 position than other milkfat substitutes. In addition, the use of Betapol in infant formula can lead to improved mineral and fat absorption and less calcium soap formation within the intestinal lumen resulting in softer stools. 

Constitution of Fats and Oils.—These acids which have all been previously discussed (pp. 136 and 170) embrace the more common ones that are found as esters in most oils and fats. The tri-acid ester of glycerol and palmitic acid may be taken as an example of a typical fat. It is exactly analogous to the ester of glycerol and acetic acid which we have just considered, and its formula is ... 

The response of scuffing to load can be treated as a temperature effect. Spikes and Cameron [35] showed that for steel rubbing at medium speed (1.34 cm/s) lubricated by palmitic acid in n-hexadecane a linear relation between tog C and is obtained when is calculated from the formula...

Unfortunately, sueh formulas have resulted in poor absorption of fats and minerals, particularly when studied in infants dining the first few weeks of life [62, 91, 92]. This is because PA is present in the sn-1 position (human breast milk, lard native, enzyme-direeted and randomly ehemieally interesterified fats plant) eompared with the sn- and sn-3 positions (bovine milk, randomly ehemieally interesterified lard or crude palm oil). It was found the relative absorption of palmitic acid and full fat was linearly related to the proportion of palmitic acid in the sn-1 position of the TAG in human infants. Panereatie lipase selectively hydrolyses the fatty aeids at the sn- and sn-3 positions, yielding free fatty acids and monoacylglycerols (MGs). The TAG sn-1 position is absorbed more effieiently than free palmitic acid and it is conserved through the digestion, absorption and ehylomicron TAG synthesis [63, 91].
