TLC spots with marker reveal the presence of free fatty acids (FFA), diglyceride (DG), monoglyceride (MG) but negligible amount of TG. GCMS of fatty acid— methyl esters (FAME) from lion mane presented evidence for fatty acids ranging from C9-C24 (Figs. 5.3- 5.6). Low volatility molecules like nonanedioic acid (Fig. 5.3), tridecanoic acid (Fig. 5.4), 12-methyl tridecanoic acid were also present in lion hair lipids. In addition fatty acids such as myristic, pentadecanoic, palmitic, heptanoic, stearic and octadecenoic acids (Fig. 5.5) have also been detected. Erucic... 

Milk fat and milk solids-not-fat (MSNF) are most commonly obtained from cream and condensed skim milk, but may also be obtained from a combination of fluid milk, condensed whole milk, frozen cream, frozen condensed milk, nonfat dry milk, dry whole milk, and butter. Sweeteners used in the mix normally include a combination of liquid or dry sucrose, corn sweetener, high-fructose corn sweetener, and corn syrup solids. Ice cream stabilizers are formulated to contain one or more polysaccharide hydrocolloids, e.g., carboxymethyl cellulose, locust bean gum, carageenin, alginate, and other gums. Ice cream emulsifiers normally contain monoglycerides and diglycerides of palmitic and stearic... 

Various lipids including triglycerides (e.g., trilaurin, trimyristin, tripalmitin and tristearin) and fatty acids were evaluated as carrier materials in sustained-release insulin implants. The drug/wax powder blend was compressed into a disc and implanted subcutaneously into Wistar rats. Monoglycerides tested eroded too fast and were not suitable. The triglycerides only sustained-the insulin release briefly. The best sustained-release properties were obtained with palmitic and stearic acids as the carrier materials.

Table I compares the specifications for the 40-55% grades. Glyceryl monostearate PhEur and mono- and di-glycerides USPNF. PhEur divides glyceryl monostearate 40-55 into three types according to the proportion of stearic acid ester in the mixture, and those specifications are presented in Table II. Table III presents the specifications for glyceryl monostearate USPNF (90% monoglycerides). Since the JP specifications are broad enough to encompass both grades, JP is included in both Table I and Table III.

The fatty acids have special names. The saturated Cjg acid is called stearic , and the compound listed is 2,3-dihydroxypropyl stearate. The alcohol residue is glycerol. Since only one hydroxyl is esterified this type of ester is called a monoglyceride and the compound may be named monoglyceryl stearate. It is valuable in food processing as an emulsifier. 

Hydrolysis of Fats and Starches. The acceleration of hydrolysis of fats by alkali under pressure of 100 atm has long been known and practiced. In general, the rate of hydrolysis of the glycerides of stearic, palmitic, etc., acids increases in the order tri-, di-, and monoglyceride.

Azeotropic water entrainment. A mixture of glycerol, acetone, chloroform, and some p-toluenesulfonic acid refluxed 1-2 hrs. with separation of the water formed, stearic acid added to excess acetal, refluxing continued ca. 3 hrs., the resulting isopropylideneglycerol stearate dissolved in 2-methoxyethanol, and heated 30-40 min. with finely powdered boric acid on a steam bath -> a-mono-stearin. Y ca. 85% purity 98-99%.—This method is suitable for the prepn. of a-monoglycerides of satd. acids from Gg-acids onwards. L. Hartman, Ghem. Ind. 1960, 711. 

Esters of fatty acids, primarily stearic and palmitic, and distilled monoglycerides with lactic, tartaric, citric, succinic, and related hydroxy acids have found wide application as emulsifiers and improvers in the food industry.
