Astaxanthin is a carotenoid compound naturally found in marine organisms and is often used as an ingredient in health care products and cosmetics.
Astaxanthin is a red fat-soluble carotenoid with a molecular formula of C40H52O4 and a molecular weight of 596.84. It exists in various marine organisms, including large yellow croaker, salmon, river shrimp, lobster, etc., and can also be extracted from certain microorganisms. Astaxanthin has high antioxidant properties and has a strong scavenging effect on free radicals, ROS (reactive oxygen species) and monocytes.
Antioxidant effect: Astaxanthin is a powerful antioxidant that can reduce the production of free radicals and reduce the damage to cells caused by oxidative stress, helping to prevent various diseases and slow down the aging process.
Cardiovascular protection: Astaxanthin can reduce cholesterol accumulation and oxidative damage, which is helpful in preventing atherosclerosis, hypertension and other cardiovascular diseases.
Enhance immunity: The antioxidant properties of astaxanthin can enhance the function of the immune system, improve the body's immunity, and help prevent infections and diseases.
Improve skin: Astaxanthin can improve skin elasticity and gloss by reducing the production of free radicals and stimulating collagen production, which is helpful in preventing skin aging and wrinkles.
Relieve eye problems: Because astaxanthin can penetrate the tissue of the eye, it has a certain effect in protecting and relieving eye problems, such as reducing eye fatigue and improving vision.
Definition and Chemical Structure
Astaxanthin is a xanthophyll carotenoid with the formula C40H52O4.
It has a unique molecular structure that allows it to effectively neutralize free radicals.
This structure includes a long chain of double bonds and a polar end group, contributing to its antioxidant capacity.
The molecule's stability comes from the conjugated double bond system, which allows it to withstand various oxidative stresses.
Astaxanthin's configurational flexibility enables it to integrate effectively into cell membranes, enhancing the cell's resilience against oxidative damage.
Its efficacy is often compared with other antioxidants, highlighting its strong protective qualities.
