Is ascorbic acid an antioxidant?
Ascorbic acid and its esters function as antioxidants with some substrates by protecting double bonds and scavenging oxygen.
Why is ascorbic acid an antioxidant?
Ascorbic acid also acts as an antioxidant in light-exposed foods by quenching singlet oxygen before singlet oxygen reacts with other food compounds, similar to the function of carotenoids (Chou & Khan, 1983; Jung et al., 1995).
Is ascorbic acid a good form of vitamin C?
There are several forms of vitamin C. In supplements, vitamin C usually comes in the form of ascorbic acid. However, some supplements contain other forms, such as sodium ascorbate, calcium ascorbate, or ascorbic acid with bioflavonoids. According to the NIH , all forms of vitamin C are similarly beneficial.
What type of antioxidant is vitamin C?
Vitamin C is an electron donor, and this property accounts for all its known functions. As an electron donor, vitamin C is a potent water-soluble antioxidant in humans. Antioxidant effects of vitamin C have been demonstrated in many experiments in vitro.
What does antioxidant C mean?
Abstract. Vitamin C or ascorbic acid (AsA) is a naturally occurring organic compound with antioxidant properties, found in both animals and plants. It functions as a redox buffer which can reduce, and thereby neutralize, reactive oxygen species.
Why is vitamin C called ascorbic acid?
Later on, Szent Györgyi and Haworth chemically identified “C” as ascorbic acid, and named it so because ascorbic means “anti-scurvy.” Over the next century, what we now know as vitamin C became one of the most popular drugs in human history.
What does vitamin C ascorbic acid do?

Is vitamin C the best antioxidant?
Vitamin C is a strong antioxidant that can boost your blood antioxidant levels. This may help reduce the risk of chronic diseases like heart disease.
Why is vitamin C the best antioxidant?
There is interest in the antioxidant role of vitamin C, as research has found the vitamin to neutralize free radical molecules, which in excess can damage cells. Vitamin C is also involved in the body’s immune system by stimulating the activity of white blood cells.
What vitamin is a antioxidant?
Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin. This fact sheet provides basic information about antioxidants, summarizes what the science says about antioxidants and health, and suggests sources for additional information.
What is real vitamin C?
According to the Vitamin C Foundation “What is commonly called vitamin C, the ascorbate ion, or simply ascorbic acid, is the real vitamin C.” Humphries discovered that synthetic vitamin C in the form of oral sodium ascorbate powder is actually the most efficient and well-tolerated option.
What does C ascorbic acid prevent?
Vitamin C is one of many antioxidants that can protect against damage caused by harmful molecules called free radicals, as well as toxic chemicals and pollutants like cigarette smoke. Free radicals can build up and contribute to the development of health conditions such as cancer, heart disease, and arthritis.
Why is vitamin C complex and not ascorbic acid?
“99.9% of the drivel on the Internet related to “vitamin C” is actually referring to ascorbic acid. Ascorbic acid, or its reduced form ascorbate, does not have the critical enzyme tyrosinase (a copper-containing enzyme). That is what makes whole food vitamin C complex so (therapeutic)!
What is ascorbic acid and stress?

Why is vitamin C called an antioxidant?
Vitamin C is called an antioxidant because electrons from vitamin C can reduce oxidized species, or oxidants. However, the same electrons from ascorbate can reduce metals such as copper and iron, leading to formation of superoxide and hydrogen peroxide, and subsequent generation of reactive oxidant species.
What is the value of vitamin C?
Vitamin C (ascorbic acid (AA)) is very popular for its antioxidant properties. Consequently, many other important aspects of this multifaceted molecule are often underestimated or even ignored.
