Occurrence and distribution of D-cysteinolic acid in fish and shellfish.
1. An unknown compound which is very similar to taurine was detected in the extract of sardine Sardinops melanosticta. 2. It was identified as D-cysteinolic acid: 2-amino-3-hydroxy-1-propanesulfonic acid from instrumental analysis. 3. This may be the first report in which the occurrence of D-cysteinolic acid in fish has been demonstrated. 4.
