Astaxanthin also known as astacin, is a kind of carotenoids. There are many well-known stars in carotenoid family, such as beta-carotene, lutein, canthaxanthin, lycopene and so on, astaxanthin is the one with the most health benefits in this family, because it has strongest inoxidizability.
Its antioxidant activity is far exceeding the existing antioxidants. The free radicals scavenging capacity is: 6,000 times than the natural VC, 800 times than coenzyme Q10, 550 times than natural VE tea, 200 times than polyphenols, 150 times than anthocyanins, 75 times than lipoic acid.
Natural astaxanthin's role is mainly in preventing atherosclerosis and related diseases, clinical studies have shown that the oxidation of low-density lipoprotein (LDL) is an important reason to cause atherosclerosis. Astaxanthin in vivo has significantly increased high density lipoprotein (HDL) and reduce LDL efficacy, while B-carotene and canthaxanthin have not such effect, so that speculated astaxanthin can reduce the oxidation of apolipoprotein, available to make an agent to prevent arteriosclerosis, coronary heart disease and ischemic brain damage.
Maintaining the eyes and central nervous system healthy, unsaturated fatty acids and high concentrations oxygen containing in human retina multiple is higher than any other tissue. When the high-energy blue light working in the retina, the singlet oxygen produced by photo-oxidation and oxygen free radicals oxidative damage the retina. For humans and other animals, the carotenoids in diet are necessary to maintain eye health, can quench these active oxygen, and help protect the retina anti oxidative damage, clinically useful for the treatment of “age-related macular degeneration”. Recent studies by astaxanthin suppliers indicate that astaxanthin through the blood-brain barrier can effectively prevent the oxidation of the retina, and photoreceptor cell damage, astaxanthin has a good effect in preventing and treating “age-related macular degeneration”, improving retinal function.
Protect the skin from light damage, UV radiation is an important cause of skin photoaging and skin cancer. Cosmetic raw material suppliers studied found that astaxanthin on transferrin glutamine enzyme has a special effect, can consume putrescine when the skin under the light, and the inhibitory effect of oral administration of astaxanthin on accumulating putrescine is stronger than oral vitamin A, that is to say astaxanthin’s strong antioxidant activity can be used as the potential of the light-protecting agent, used to prevent skin photoaging.
Enhance the immune system, the singlet oxygen has a cytotoxic effect on the animal's immune system, radicals generated by catalyzes can accelerate the degradation of the macrophage cell membrane, causing phagocytic efficiency and dysfunction. Astaxanthin can significantly affect the animal's immune function, significantly promote the ability of antibody-producing spleen cells while the antigen existing, enhanced human blood cells immunoglobulin producing under the T-cell stimulation, also be able to partially restore aged mice humoral immune system, show that in the antigen invasion early stage, astaxanthin can enhance the humoral immune response. Astaxanthin can also enhance the release of interleukin-1A and tumor necrosis factor A in mice, and its role is much stronger than the B-carotene and canthaxanthin. Thus believe that astaxanthin has the use of optimum induce cell division activity and has an important role in immune regulation, can be used as immunostimulants.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
The Evolution and Impact of Abamectin and Emamectin Benzoate in Pest Control
Abamectin and its derivative, emamectin benzoate, have emerged as pivotal substances in the realm of pest control, offering a broad-spectrum efficacy against various pests while maintaining a favorable environmental profile. As the agricultural industry continues to evolve, these compounds have adapted to meet the growing challenges of pest resistance, expanding their market applications and maintaining cost-effectiveness despite rising production costs.
