FREE RADICALS & DISEASES
Normally, free radicals are necessary for bodies, but excessive free radicals can cause the imbalance of physiological function, then lead to oxidative stress evolving in various diseases ( literatures indicate that free radicals are the source of various diseases).
Our bodies cannot operate without oxygen, and once a large number of free radicals increased, the body under oxidative stress will cause the repair system to fail in removing excessive free radicals. In special cases, the body need replenish antioxidants in vitro to remove excessive free radicals.
DEVELOPMENT OF ANTIOXIDANTS
L-ERGOTHIONEINE –A NEW TYPE OF NATURAL ANTIOXIDANT
With advantages of multi-functions, EGT stands out among many other antioxidants.
With advantages of multi-functions, EGT stands out among many other antioxidants.Advantages (compared with glutathione, cysteine etc.):
——EGT is easier to accumulate in cells and the concentration is more stable than other antioxidants.
——EGT is more effective on reducing cell death caused by pyrogallol.
——EGT mainly scavenges ROS to prevent oxidation, while glutathione and others scavenge free radicals, that is, other antioxidants scavenge oxidation products.
COMPARISON OF ANTIOXIDATION
Results: EGT was the most active scavenger of free radicals as compared to classic antioxidants as GSH, uric acid and trolox. In particular, the highest antioxidant capacity exhibited by EGT vs. peroxyl radicals resulted 25% higher than the value obtained with the reference antioxidant trolox. The scavenging capacity of EGT towards hydroxyl radicals was 60% higher, as compared to uric acid,which represent the reference antioxidant vs. hydroxyl radicals. Finally, EGT showed the highest antioxidant activity also towards peroxynitrite, with a scavenging capacity 10% higher than that of uric acid.
EGT also has effects on regulating intracellular energy,
improving the survival rate of sperm,
protecting the liver from injury,
developmental defects and cataract.
