P-Hydroxyphenyllactic acid

In an infant with a serum phenylalanine concentration greater than 4 mg dl, the following have been recommended administration of 100 mg of ascorbic add 24 h prior to obtaining a repeat blood specimen, measurement of phenylalanine and tyrosine in blood, and evaluation of urine for the presence of phenylalanine, O-hydroxyphenylacetic acid, and phenylpyruvic acid, as well as tyrosine and tyrosine derivatives (p-hydroxyphenyllactic acid and p-hydroxyphenylpyruvic add) by chromatography and spot tests. Most infants will be found to have a transient defect that demands a new testing. [Pg.397]

DANISHEFSKY, S., M. HIRAMA, N. FRITSCH, J. CLARDY. 1979. Synthesis of disodium prephenate and disodium epiprephenate. Stereochemistry of prephenic acid and an observation on the base-catalyzed rearrangements of prephenic acid to p-hydroxyphenyllactic acid. J. Am. Chem. Soc. 101 7013-7018. [Pg.49]

An alternate reaction of prephenic acid was found in extracts of coli nxutants blocked in the conversion to phenylpyruvate. The product of the alternate reaction is p-hydroxyphenyllactic acid. Presumably oxidation to ketotyrosine and transamination follow the formation of p-hydroxyphenyllactate to yield tyrosine. [Pg.343]

The elevated 4-hydroxyphenyl acids are represented mainly by p-hydroxyphenyllactic and p-hydroxyphenylacetic acids due to its instability, p-hydroxyphenylpyruvic acid is less regularly found (B26). [Pg.91]
