“…He found that the lipid classes and composition of the FGM in both of species almost the same. While Shahin et al [1987] isolated the fat globule membrane neutral lipids (FGM-NL) from Egyptian buffalo, goat and cow's milk, fractionated by TLC and individual fractions were quantitatively determined. Triglycerides were found to be the main fraction in FGM-NL from all species, followed by free fatty acids, 1, 2 diglycerides, 1, 3 diglycerides, monoglycerides and then cholesterol.…”

processes and defense mechanisms in the newborn [Cavaletto et al., 2006].The stabilizing membrane acts as reactive sorts on the interface between the barriers of milk serum. As such, it can be globule and rate-controlling for a host of physical and of enzymes chemical interactions, e.g., binding mace elements; controlled release of the polar materials products of lipolysis; transfer of milk serum; maintenance of emulsion into stability by prevention of globule fusion; availability of fatty acids and cholesterol for micellar absorption in the small intestine; and destabilization by creaming, clumping, churning, freeze-thaw, and heating, resulting in loosely bound substances into milk transfer serum. Worthy of notice is that the interactions are dynamic.Moreover, it is assumed that the MFGM proteins also possess specific nutritional properties. As such, due to their origin, composition and structure, MFGM polar lipids and proteins could be used as an emulsifier or stabilizer, combining technological and nutritional functionality [Mulder & Walstra, 1974;Anderson & Cawston, 1975;Patton & Keenan, 1975;Patton & Jensen, 1975, 1976Keenan et al., 1983;Mather & Keenan, 1983; McPherson & Kitchen, 1983; Walstra & Jenness, 1984;Keenan & Dylewski, 1985 Bucbheim, 1986;Mather, 1987; Keenan et al., 1988;Keenan & Dylewski, 1995;Keenan & Patton, 1995;Mather & Keenan, 1998;Danthine et al., 2000; Keenan, 2001; Keenan & Mather, 2002; Ollivier--Bousquet, 2002;Lopez et al., 2006Lopez et al., , 2007Sanchez-Juanes et al., 2009;Zamora et al., 2009]. Composition, Properties and Nutritional Aspects of Milk Fat Globule Membrane -a Review Mohamed Mansour El-Loly Dairy Department, National Research Centre, Dokki, Cairo, EgyptKey words: milk fat globule membrane, mammary gland, isolation, structure, stability, nutritional, nutraceuticalIn the last few years, knowledge on the composition and properties of the milk fat globule membrane (MFGM) increased significantly. It is now recognized that the MFGM is highly complex in structure and composed of different protein and lipid components with specific technological and nutritional properties. As such, MFGM materials have been isolated and characterized as valuable ingredients for incorporation into new food products. However, MFGM are also sensitive to modification during isolation and processing, and care should be taken to standardize the composition and characteristics of the membrane to maintain its unique properties during application in food products.The MFGM is subject to changes in composition and structure from the moment the fat globule leaves the mammary secretory cell. Upon milk harvesting and further milk handling, further changes to the MFGM take place. Depending on the type and degree of treatment, this may involve different physico-chemical interactions between various membrane components, the loss of membrane components and/or adsorption of components from the milk plasma. However, the effects appear to be variable and dependent on physiological (animal) factors, and much remains ...

“…Many carbon materials, including MWNTs [ 34 - 36 ], have their acidic and basic characteristics determined using acid-base titration methods [ 37 - 40 ]. For the purpose of measuring the concentration of free fatty acid in biological matrices, several studies have been performed [ 41 - 45 ]. Mohammed et al [ 46 ] has described an acid-base titrimetric method for sildenafil citrate determination in a tablet and bulk form.…”

Facile Titrimetric Assay of Lysophosphatidic Acid in Human Serum and Plasma for Ovarian Cancer Detection

Herein, an instrument free facile acid-base titrimetric methodology is reported for lysophosphatidic acid (LPA) measurement in serum and plasma samples for ovarian cancer detection. The concept is based on the titrimetric method in which alkaline solution was titrated with free fatty acid. Free fatty acid is generated due to action of the lysophospholipase to LPA. A phospholipid derivative known as LPA can function as a signaling molecule. A glycerol backbone serves as the foundation for phosphatidic acid, which also has bonds to an unsaturated fatty acid at carbon-1, a hydroxyl group at carbon-2, and a phosphate molecule at carbon-3. Free fatty acid and glycerol-3-phosphate are formed when LPA reacts with lysophospholipase. The formation of free fatty acid depends on the concentration of LPA. The standard graph of known concentrations of LPA, LPA spiked serum and LPA spiked plasma was plotted. The concentration of LPA in unknown serum and plasma were calculated from the standard graph. The limit of detection of LPA in spiked serum and plasma samples via titrimetric assay was calculated as 0.156 μmol/L. A patient's chance of survival may be outweighed by an early diagnosis of ovarian cancer.
