N-acetyl phenyl cysteine (NAP) is a metabolite derived from benzene, a chemical that has been widely used in the past as an industrial solvent. Due to its toxicity and associated health risks, the use of benzene has been significantly reduced. However, exposure to benzene can still occur in occupational settings, as well as in the general environment and at home, due to the widespread use of benzene-containing petroleum products such as motor fuels and solvents.

Benzene exposure has been linked to a range of health issues, including respiratory, hepatic (liver), cardiovascular, immune, nervous, and endocrine system dysfunctions. Monitoring NAP levels can help assess an individual’s exposure to benzene and provide insights into potential health risks associated with this toxic compound.

N-acetyl phenyl cysteine (NAP) is a metabolite of benzene. 

Benzene is an organic solvent that is widespread in the environment. Benzene is a by-product of all types of industrial processes and combustion, including motor vehicle exhaust and cigarette smoke, and is released by outgassing from synthetic materials. Benzene is an extremely toxic chemical that is mutagenic and carcinogenic. High exposures to benzene cause symptoms of nausea, vomiting, dizziness, lack of coordination, central nervous system depression, and death. It can also cause hematological abnormalities.

NAPR is a metabolite of 1-bromopropane.  Chronic exposure can lead to decreased cognitive function and impairment of the central nervous system.  Acute exposure can lead to headaches.

1-bromopropane is an organic solvent used for metal cleaning, foam gluing, and dry cleaning. Studies have shown that 1-BP is a neurotoxin as well as a reproductive toxin. Research indicates that exposure to 1-BP can cause sensory and motor deficits. Chronic exposure can lead to decreased cognitive function and impairment of the central nervous system. Acute exposure can lead to headaches.

N-acetyl-S-(2-carbamoylethyl)cysteine (NAE) is a metabolite of acrylamide, which is detoxified through a two-step process.

First acrylamide is metabolized by the cytochrome P450s.  

Second it is conjugated to glutathione in order to make it more water soluble.

NACE is a metabolite of acrylonitrile, which is used in the production of acrylic fibers, resins, and rubber.

Acrylonitrile is metabolized by the cytochrome P450s and then conjugated to glutathione. Supplementation with glutathione should assist in the detoxification of acrylonitrile.

N-acetyl(2-hydroxypropyl)cysteine (NAHP) is used in the production of plastics and is used as a fumigant (=gaseous pesticides).

This chemical is a metabolite of propylene oxide. Propylene oxide is used to make polyester resins for textile and construction industries. It is also used in the preparation of lubricants, surfactants, and oil demulsifiers. It has also been used as a food additive, an herbicide, a microbicide, an insecticide, a fungicide, and a miticide. Propylene oxide is a probable human carcinogen.

NADB is a metabolite of 1,3 butadiene, which is evident of exposure to synthetic rubber such as tires. 1,3 butadiene is a known carcinogen and has been linked to increased risk of cardiovascular disease. Individuals that come into contact with rubber, such as car tires, could absorb 1,3 butadiene through the skin.

Elevated N-acetylaspartic acid is due to the genetic disorder Carnavan’s disease, a potentially fatal disease causing spongy degeneration of the brain. 

What is Carnavan’s disease?

Canavan disease is a rare inherited disorder that damages the ability of nerve cells (neurons) in the brain to send and receive messages. This disease is one of a group of genetic disorders called leukodystrophies. Leukodystrophies disrupt the growth or maintenance of the myelin sheath, which is the covering that protects nerves and promotes the efficient transmission of nerve impulses.

N-Acetylcysteine (NAC) is a powerful antioxidant that increases the glutathione reserves in the body. 

Together with glutathione, N-Acetylcysteine (NAC) directly binds to toxic metabolites. Although N-Acetylcysteine (NAC) may be beneficial under certain conditions, excessive use of the supplement could be harmful.

N-Butyrate is one of the short-chain fatty acids produced by Lactobacillus and Bifidobacteria in the colon. It becomes a food supply capable of providing up to 30% of the energy needed by colon cells. N-butyrate improves colon health.
