Metabolite Identification
Common Name4-Hydroxycrotonic acid
Description4-Hydroxycrotonic acid was first identified in biopsies of renal tissue from patients with chronic glomerulonephritis. 4-Hydroxycrotonic acid is usually undetectable in normal urine and serum. Experimentally, 4-Hydroxycrotonic acid increases initially with kidney ischemia but later reaches almost control levels. (PMID: 7107749 , 6833421 ).
