Cysteine (L-Cysteine, N-Acetyl-Cysteine, N-acetylc-Cysteine)
Probably the most exciting and
important role for the amino acid cysteine, or L-Cysteine as
it is found in nature, is its properties of helping the body
scavenge and rid itself of poisonous materials. In the liver,
cysteine helps another amino acid called glutathione to detoxify
carcinogens and other dangerous chemicals. In all the rest of
the cells of the body, it is thought to serve as the major scavenger
of hazardous oxidants. L-Cysteine acts to protect the cells
of the alveoli in the lungs against damage of cigarette smoke,
specifically the chemicals of acrolein, formaldehyde and acetaldehyde
found in cigarette smoke. The tar and other toxic chemicals
within cigarette smoke are known to impair the alveoli's scavenger
macrophages to engulf and kill bacteria. Cysteine, along with
vitamin C improves the bactericidal effectiveness of these cells.
Also, because of the select thiol grouping (-SH) at the ending
of this amino group, cysteine is the amino acid which gives
glutathione its antioxidant powers and properties. In fact,
how much cysteine is available to the body is believed to directly
effect how much glutathione is produced and used as an antioxin!
Recent research also indicates that it alone could provide protection
against HIV-1. Low levels of glutathione in CD4 T-cells are
linked to decreased survival rates for HIV-positive individuals.
Orally administered NAC (n-acetylcysteine) and glutamine, nutritional
precursors of GSH (but cheaper than pure GSH), worked very well
in restoring whole blood glutathione levels, and those with
low CD4 cells survived twice as long when taking NAC and glutamate
supplements. The authors report that replenishing glutathione
levels might be a key to improving survival of HIV-positive
patients, however more studies are needed. (Herzenberg, L.A.,
et al, Glutathione deficiency is associated with impaired survival
in HIV disease, Pro Natl Acad Sci, 1997, 94: 1967-1972.).
See GlutathioneAlong with stimulating L-Glutathione supplies
in the body, NAC, a form of L-Cysteine has been shown to raise
the levels of HDL Cholesterol (the good or protective type of
cholesterol) NAC splits the Lp(a) and its sticky protein band
apart on the cholesterol molecule, which acts to render it harmless.
NAC also acts to reduce levels of homocyeine, protecting against
homocytein's damaging effects on the arteriesSkin texture and
flexibility are thought to be related to cysteine function by
virtue of free radical inactivation, although more research
has yet to be done on this.
