Role of Cysteine

There are many important amino acids found in the human body. These tiny nutrients, which include cysteine in their ranks, perform and promote healthy bodily functions. Cysteine is a nonessential amino acid, meaning it is made within the body. However, its levels should be kept in check.

Identification

• Cysteine is a amino acid that comes from methionine, another amino acid. It is also found in a number of common foods, including poultry, broccoli and yogurt; a deficiency of cysteine is rare.

Mucous

• Mucous that has settled in the lungs occurs when a person has respiratory problems. Cysteine helps to break down proteins in mucous in order to help get rid of it.

Taurine Production

• Taurine, an amino acid that helps regulate the heart and absorb fat-soluble vitamins, is derived from the oxidation of cysteine in the pancreas.

Glutathione

• Cysteine helps the antioxidant glutathione operate properly. Glutathione is present in all bodily tissues and helps to fight off free radicals, while playing an important role in detoxification as well.

Acetaminophen Poisoning

• Cysteine is often given intravenously to prevent liver and kidney damage from overdosing on acetaminophen, commonly known as Tylenol.
