Phrenosinic acid

Phosphorus trihydride, see P-10101 Photodeoxytridachione, P-30086 Phrenosic acid, see H-10229 Phrenosinic acid, see H-10229 2,3-Phthalyfuran, see N-20006 Phtheirospermoside, in D-30235 Phygrine, P-10104... [Pg.491]

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 proof of the linkage between the lipophilic (N-acylsphingosine) and hydrophilic (sulfated D-galactopyranosyl) moieties of the sulfa-tide was obtained by mild hydrolysis with acid selective cleavage of the sulfate group resulted in phrenosin.95... [Pg.403]

Phrenosin, N-[I-[( i-D-Galactopyra nosyloxy)meth -ylJ-2-hydroxy-3-heptadeceny l]-2-hydroxytet racosanamide Cerebroo. C H jNO mol wt 828.23. C 69.60%, H 11.32%, N 1.69%, O 17.39%, Cerebroside easily separated from a commercially available beef spinal cord lipid concentrate or from nerve tissue. A large proportion of its fatty acid content (23%) is 2-hydroxystearic acid, the rest is cere-bronic (2-hydroxylignoceric) acid. Isoln Radio er of.. J. Biot. Chem. 219, 977 (1936) Skipski el al.

The fatty acid components are usually lignoceric acid, CH3(CH2)22— COOH (of kerasin), 2-hydroxylignoceric acid (of phrenosin), A -lignoceric acid (of nervone), behenic acid, or stearic acid. [Pg.560]

Hydroxy acids are represented by the Cerebronic Series, including phrenosinic or cerebronic acid from phrenosin of brain tissue and the Bicinoleic Series, including ricinoleic acid, the glyceride of which is the chief constituent of castor oil, obtained from the seeds of Ricinus... [Pg.162]

Phrenosin, C48H9iN0g, is a white, micro-granular powder. On hydrolysis it yields (a) galactose (6) sphingosinol and (c) phreno-sinic acid. [Pg.169]

Kerasin, nervone, and hydroxynervone resemble phrenosin but for the fact that each contains a different aliphatic acid united to the... [Pg.169]
