L-Cysteine: amino acid for parenteral nutrition
L-cysteine is a plant-derived amino acid that is used as a parenteral protein nutrition agent. It is manufactured in Japan by Ajinomoto Co. Ltd. and Kiowa Hakko Kogyo Co.
Parenteral nutrition is a method of nutrition in which nutrients enter the body through a vein. This method is used in cases where the digestive system cannot provide the body with enough nutrients.
L-cysteine is an essential amino acid for protein synthesis in the body and is also a source of sulfur. It is a constituent of many proteins, such as keratin, which is a major component of hair, nails and skin, and glutathione, which is an important antioxidant.
L-cysteine is also used as an antioxidant that helps protect cells from free radicals that can damage DNA and lead to various diseases.
L-cysteine is available as an amino acid for parenteral nutrition. It can be used as monotherapy or in combination with other amino acids and nutrients.
There are a number of contraindications to the use of L-cysteine, including allergic reactions to this amino acid, acute liver failure and pregnancy. Before using L-cysteine, you should consult your doctor.
Thus, L-cysteine is an important amino acid for protein synthesis in the body, and is also a source of sulfur and an antioxidant. It can be used as a means of parenteral protein nutrition in cases where the digestive system cannot provide the body with sufficient nutrients.
