What does vitamin C represent?
Vitamin C, also known as ascorbic acid, is a water-soluble nutrient found in some foods. In the body, it acts as an antioxidant, helping to protect cells from the damage caused by free radicals. Free radicals are compounds formed when our bodies convert the food we eat into energy.
What does the L mean in L ascorbic acid?
Vitamin C
Pure Vitamin C is known as L-Ascorbic Acid. The “L” in front of Ascorbic is a reference to how the molecule itself rotates to light and refers to its source. L-Ascorbic Acid comes from natural sources such as oranges.
What is the difference between ascorbate and ascorbate?
Ascorbic acid is an organic acid whereas sodium ascorbate is a mineral salt of ascorbic acid. Sodium ascorbate is milder than ascorbic acid as it is buffered and has less acidity. Sodium ascorbate has an ester function whereas ascorbic acid does not have an ester function in it.
What is the function of ascorbate?
Ascorbate is best known for its function as an antioxidant and for its role in collagen synthesis. Collagen deficiency results in the symptoms of scurvy.
What is difference between ascorbic acid and L-ascorbic acid?
Ascorbic acid is the name of vitamin C in the body, and L in L-ascorbic acid refers to the way the molecule rotates to light. L-ascorbic acid is found in nature in fruits and vegetables such as oranges, broccoli, leafy greens, grapefruit, and peppers.
Is ascorbic acid same as L-ascorbic?
Ascorbic acid, also known as vitamin C or L-ascorbic acid , is a naturally occurring organic compound with antioxidant properties. Ascorbic acid is found in plants and food, including citrus fruits, tomatoes and green vegetables.
How do you analyze vitamin C?
Direct ultraviolet spectrophotometry is a fast, simple and reliable method for the determination of vitamin C. This method can be done through alkaline treatment and the maximum absorption of vitamin C falls at 243nm at pH2 (Yanshan, 1997).
In which substance is vitamin C present?
Citrus fruits, tomatoes and tomato juice, and potatoes are major contributors of vitamin C to the American diet [8]. Other good food sources include red and green peppers, kiwifruit, broccoli, strawberries, Brussels sprouts, and cantaloupe (see Table 2) [8,12].
What is sodium ascorbate used for?

It has a role as a water-soluble vitamin, a vitamin C, a food antioxidant, a flour treatment agent, a coenzyme, a plant metabolite, a human metabolite, a Daphnia magna metabolite and a reducing agent.
What is the E number for sodium ascorbate?
Sodium ascorbate. Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium). As a food additive, it has the E number E301 and is used as an antioxidant and an acidity regulator.
How do you make sodium ascorbate from sodium bicarbonate?
Sodium ascorbate is produced by dissolving ascorbic acid in water and adding an equivalent amount of sodium bicarbonate in water. After cessation of effervescence, the sodium ascorbate is precipitated by the addition of isopropanol.
Is sodium ascorbate more bioavailable than other vitamin C supplements?
It has not been demonstrated to be more bioavailable than any other form of vitamin C supplement. Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium).
