L-Ergothioneine is a naturally occurring amino acid and is a thiourea derivative of histidine, containing a sulfur atom on the imidazole ring. This compound occurs in relatively few organisms, notably actinomycetota, cyanobacteria, and certain fungi. Ergothioneine was discovered in 1909 and named after the ergot fungus from which it was first purified, with its structure being determined in 1911.
In humans, ergothioneine is acquired exclusively through the diet and accumulates in erythrocytes, bone marrow, liver, kidney, seminal fluid, and eyes. Although the effect of ergothioneine in vivo is under preliminary research, its physiological role in humans is unknown. Ergothioneine is sold as a dietary supplement.
Application of L-Ergothioneine:
1. Use as a unique antioxidant. Ergothionein is a highly protective, non-toxic, natural antioxidant that is not easily oxidized in water, which allows them to be present in concentrations up to mmol in certain tissues and stimulates the cells' natural antioxidant defense system.
2. Adds to cosmetics as a skin protectant. Ultraviolet UVA in sunlight can penetrate into the dermis of human skin, affecting the growth of epidermal cells, making the surface cells senile and causing premature skin aging, while ultraviolet UVB is easy to lead to the occurrence of skin cancer.
3. Application in ophthalmology. In recent years, ergothiamine has been found to play a key role in eye protection, so many researchers hope to develop an ophthalmic product to facilitate the development of eye surgery.
4. In the field of health products, it can prevent the occurrence of cancer, etc., and can be made into functional food and drinks, etc. In the field of cosmetics, it can be used for anti-aging, and can be made into sunscreen and other products.
Food:
Ergosulfan can regulate intracellular redox reactions, participate in intracellular energy regulation, and is a physiological protector of cells. Its biological and pharmacological properties are extremely safe and stable.
Using ergot in antioxidant products not only has a strong antioxidant effect on its own, but also synergizes with other antioxidants to enhance its vitality. High purity ergot sulfur is extremely safe and can be used in pregnant women and sensitive muscles. According to EU and US regulations, it has been approved for use in formula foods for pregnant women and infants to protect the health of mothers and babies.
