From saponification of cerebrosides, lipids found in the membranes of brain and nerve cells therc is obtained nervonic acid. This acid rapidly decolorizes dilute KMn04 and Br2/CCl4 solutions. Hydrogenation in the presence of nickel yields tetracosanoic acid, W-C23H47COOH. Vigorous oxidation of nervonic acid yields one acid of neutralization equivalent 156 3 and another acid of neutralization equivalent 137 2. What structure or structures are possible for nervonic acid ... [Pg.1067]

Phrenosin gives equimolar amounts of sphingosine, D-galactose, and 2-hydroxytetracosanoic (phrenosinic or cerebronic) acid on acid hydrolysis. Kerasin has similar constituents, but the fatty acid component is tetracosanoic acid. [Pg.396]

The fatty acids in amide linkage on the phytosphingosine residue in the phytosphingolipid molecule proved to be cerebronic (2-hydroxytetracosanoic) acid and lignoceric (tetracosanoic) acid, and, in soya-bean phytoglycosphingolipids, palmitic and stearic acids. [Pg.410]

The fatty acid linked to the amino group of the sphingosine or sphinganine part may also differ, but, in the gangliosides isolated bom nervous tissues, the main fatty acid is stearic acid (80-90%) and, in the gangliosides of spleen and erythrocytes,178 tetracosanoic acid (docosanoic acid, tetracosenoic acid). [Pg.417]

Lignooeric Acid. Tetracosanoic acid, mol wt 368.62. C 78.19%. H 13.13%, O 8.68%. CaH47-COOH. Obtained from beechwood tar Or by the distillation of rotten oak wood Sullivan, Ind. Eng. Chem. 8, 1027 (1916). Most natural fats contain small amounts (0.2-1%). The seed fat of the Indian tree Adenanthera pamnina is said to contain 25%. Synthesis Fieser, Szmuszkovicz, J. Am. Chem. Soc. 70, 3352 (1948). [Pg.864]
