Ascorbic acid, commonly known as Vitamin C, is a vital nutrient for humans and certain other animal species. It is a water-soluble vitamin that plays a crucial role in various bodily functions, including the synthesis of collagen, the absorption of iron, the proper functioning of the immune system, wound healing, and the maintenance of cartilage, bones, and teeth. Ascorbic acid is also an antioxidant, helping to protect cells from the damage caused by free radicals.
Ascorbic acid is a white or slightly yellow crystalline powder with a slight acidic taste. It is highly soluble in water and slightly soluble in alcohol. The chemical formula of ascorbic acid is C6H8O6, and its molecular weight is 176.12 g/mol. The structure of ascorbic acid consists of a six-carbon lactone ring with two enolic hydroxyl groups that are responsible for its acidic properties.
The Chemical Abstracts Service (CAS) number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. The CAS number for ascorbic acid is **50-81-7**. This identifier is widely used by chemists and researchers to ensure precise and consistent reference to specific chemicals across various databases and publications.
Ascorbic acid is naturally found in various fruits and vegetables. Some of the richest sources include citrus fruits (such as oranges, lemons, and grapefruits), strawberries, kiwi fruit, bell peppers, broccoli, Brussels sprouts, and spinach. In addition to natural sources, ascorbic acid is also available as a dietary supplement in various forms, including tablets, capsules, and powders.
Ascorbic acid is a potent antioxidant that helps neutralize free radicals in the body. Free radicals are unstable molecules that can cause oxidative stress, leading to cellular damage and contributing to various chronic diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders. By neutralizing free radicals, ascorbic acid helps protect cells and tissues from oxidative damage.
Vitamin C is essential for the proper functioning of the immune system. It stimulates the production and function of white blood cells, which are crucial for fighting infections. Ascorbic acid also enhances the skin's barrier function, helping to protect against pathogens. Additionally, it has been shown to reduce the duration and severity of common colds and other infections.
Collagen is a structural protein that is vital for the health and integrity of skin, blood vessels, bones, and connective tissues. Ascorbic acid is a cofactor for the enzymes involved in the synthesis of collagen. Without adequate vitamin C, collagen production is impaired, leading to weakened connective tissues and delayed wound healing.
Ascorbic acid enhances the absorption of non-heme iron, the form of iron found in plant-based foods. It converts iron into a form that is more easily absorbed by the intestines. This is particularly important for individuals who follow a vegetarian or vegan diet, as they rely on non-heme iron sources.
A deficiency in ascorbic acid can lead to a condition known as scurvy, characterized by symptoms such as fatigue, weakness, anemia, gum disease, and skin problems. Scurvy is rare in developed countries due to the availability of fresh fruits and vegetables and fortified foods.
The recommended daily intake of vitamin C varies by age, sex, and life stage. For adults, the recommended dietary allowance (RDA) is 90 mg per day for men and 75 mg per day for women. Higher intakes are recommended for pregnant and breastfeeding women, as well as smokers, who have increased oxidative stress and metabolic turnover of vitamin C.
Ascorbic acid, or vitamin C, is an essential nutrient with numerous health benefits, including its role as an antioxidant, its support of the immune system, its involvement in collagen synthesis, and its enhancement of iron absorption. The CAS number for ascorbic acid is 50-81-7, which helps ensure accurate identification and reference in scientific and industrial contexts. Ensuring adequate intake of ascorbic acid through diet or supplementation is important for maintaining overall health and preventing deficiency-related conditions.
