Metabolite Identification
Common Namegamma-CEHC
Descriptiongamma-CEHC (gamma-carboxyethyl hydroxychroman) is a metabolite of vitamin E. Smokers have a significantly higher excretion level of urinary gamma-CEHC, and therefore require more vitamin E compared to non-smokers. Cigarette smoking is associated with increased oxidative stress and increased risk of degenerative disease. As the major lipophilic antioxidant, requirements for vitamin E may also be higher in smokers due to increased utilization (PMID: 15493460 ).
