What is L-Cysteine?
L-Cysteine is a sulfur-containing amino acid that is converted in the body to N-acetyl cysteine, a potent antioxidant. Cysteine is also a part of the reduced glutathione molecule, which plays an important role in the liver’s detoxification pathways. Glutathione binds and conjugates toxins, promoting their excretion.
N-acetyl L-Cysteine (NAC) is a specially modified form of the dietary amino acid cysteine and is a powerful antioxidant on it's own. When taken orally, NAC is believed to help the body make another important antioxidant enzyme glutathione (also in the Kitchen SinkT). It has shown promise for a number of conditions as noted below.
L-Cysteine is an amino acid that is closely related to Cystine. Cystine is a crystalline, sulfur containing amino acid, formed from two molecules of L-Cysteine. L-Cysteine is also a sulfur containing amino acid. The Ls are essential amino acids, meaning that they are components which cannot be produced by the body and, therefore, must be obtained from a diet or through supplementation.
L-Cysteine is important to detoxification and aids in the formation of skin. It is also important the role of hair and nail tissue repair. L-Cysteine is used in the manufacturing of antioxidants. It also aids in the protection of the liver and brain from damage due to drugs, alcohol and the toxic compounds found in cigarette smoke. L-Cysteine also helps to detoxify harmful toxins and protect the body from radiation damage.
Additional benefits of L-Cysteine include:
_ Anti-aging effects on the body, reducing the accumulation of age spots.
_ Promotes healing after surgery and severe burns.
_ Promotes the burning of fat and the building of muscle.
_ Ability to breakdown mucus found in the respiratory tract causing it to be beneficial to the treatment of tuberculosis, bronchitis and emphysema.
_ Promotes the activity of white blood cells.
What are amino acids?
There are 20 different amino acids that are needed by the body to create the various proteins needed for body growth and repair. Of these 20, 11 are created by the body and the remaining nine, which are called “essential amino acids,” cannot be produced by the body. The nine essential amino acids therefore must come from diet. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are essential amino acids. The nonessential amino acids are arginine, alanine, asparagine, aspartic acid, carntitine, cysteine, glutamine, glutamic acid, glycine, proline, serine, and tyrosine. All 20 amino acids are necessary for health.
Amino acids promote the production of various neurotransmitters and enzymes critically needed in brain metabolism. Amino acids allow smooth, balanced cognition and fluid transition from thought to disciplined action. Aid in the reduction of stress, frustration and cognitive overload.
Amino acids are the building blocks of protein in the body, they are essential for the synthesis of structural protein, enzymes and some hormones and neurotransmitters. Amino acids also affect exercise metabolisms.
Below are some of the major functions amino acids are involved in;
_ They empower vitamins and minerals to do their specific jobs correctly.
_ Some amino acids can pass through the blood-brain barrier which exists to maintain the health of the brain, the brain’s chemistry and its processes.
_ Act as neurotransmitters or precursors; some are needed to send and receive messages.
_ Aid in communication with nerve cells in other parts of the body.
