Definition and Areas of Use:
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin with many functions. Most animals and plants can produce their own vitamin C from glucose. Humans, some fruit bats, guinea pigs, and human-like primates cannot produce vitamin C and must obtain it from food.
Ascorbic acid is a monosaccharide derivative and is similar in structure to glucose and other six-carbon monosaccharides. It is colorless, white, rectangular crystals. It has a very slight specific odor. It has a sour taste and is acidic. It is optically active. It rotates polarized light to the right. It is very difficult to dissolve in acetone. It is insoluble in ether, petroleum ether, benzene, chloroform and oils. Vitamin C is chemically the enantiomer of ascorbic acid that rotates light to the left. Commercial vitamin C is generally composed of ascorbic acid crystals or calcium or sodium salts of ascorbic acid. Vitamin C (ascorbic acid) is found in very high concentrations (millimolar and above) in the aqueous sections of many animal tissues such as the spinal cord, lungs and eyes.
Accurate measurement of vitamin C is essential for both its biochemical and pharmacokinetic properties. The role of ascorbic acid in biological systems, the functions and requirements of vitamin C must be considered together with two factors: First, the biochemical properties of vitamin C, including its ability to act as both an antioxidant and an enzyme cofactor. Second, its pharmacokinetics, including intestinal absorption, serum concentration, cellular distribution, utilization, and excretion.
Ascorbic acid is found in all living tissues. The richest sources of this vitamin, which is very common in nature, are fresh fruits and vegetables. The fruits that contain the most ascorbic acid are lemon, orange, grapefruit, kiwi, pineapple, strawberry and blackcurrant. Apple, pear and plum contain less ascorbic acid compared to these. Of these fruits, especially citrus fruits (lemon, orange, grapefruit), kiwi and the outer parts (peel) of tomatoes are rich in ascorbic acid.
Vegetables, especially rosehip, cauliflower, cabbage, spinach, onion, pepper, radish, cress, parsley and Jerusalem artichoke, are the richest sources of ascorbic acid.
Areas of Use
- Boric acid has been used to control a wide variety of pests, including ants, scale insects, cockroaches, and various beetles.
- It is also used as a fungicide for citrus, a right-of-way herbicide, a fire retardant, and a wood preservative.
- When used as a herbicide it causes desiccation and disrupts photosynthesis in plants.
- Boric acid is also used in industry, with its main use being in the manufacture of textile fiberglass.
- It is used to reinforce plastics in a variety of products, such as boats, computer circuit boards, and pipes.
- It can be used in solution form or as dry powder.
- Boric acid is even used for various medical purposes, such as applying it to abraded skin or as an eye wash. It is used as an antiseptic to heal cuts and minor burns.
