THE PHENOLIC ACIDS OF HUMAN URINE

The Phenolic Acids of Human Urine*

In the course of an investigation of the metabolism of aromatic compounds in phenylketonuria, it was found that, along with the abnormal metabolism of phenylalanine in this disease, there are other striking deviations from normal. These are manifested by the excretion of greatly increased amounts of some indole acids (1) and phenolic acids (2,3) which are present in normal human urine in small ...

The phenolic amines of human urine.

The phenolic amines include substances such as epinephrine, norepinephrine, and serotonin, whose physiological importance has been known for many years, and some other amines of recent interest whose biological significance is less clear; these include dopamine (1) and octopamine (2). It is probable that still others exist and have a physiological function in some tissues of the body. The conce...

Antimutagenic effect of phenolic acids.

In the present study, the Salmonella typhimurium tester strain TA 100 was used in the plate-incorporation test to examine the antimutagenic potential of caffeic, ferulic and cichoric acids extracted from plant species of genera Echinacea (L) Moench, as well as of another phenolic acids, on 3-(5-nitro-2-furyl)acrylic acid (5NFAA) and sodium azide mutagenicity. All tested compounds possess antimu...
