So, thus from the structure of Vitamin C we can see that the functional groups present in it are:- -OH group (i.e. hydroxyl group), -C=O. (carbonyl group) and -O- group (i.e. ether group). Hence, the functional group in vitamin C are hydroxyl, carbonyl and ether respectively.
Does vitamin C have an alcohol functional group?
Vitamin C contains 4 alcohol functional groups, an alkene, and an ester.
Is vitamin C considered an organic compound?
Ascorbic acid, also known as vitamin C or L-ascorbic acid , is a naturally occurring organic compound with antioxidant properties.
Why is vitamin C an acid?
Ascorbic acid has an enediol structure conjugated with the carbonyl group in the lactone ring. The two enolic hydrogen atoms are the ones that give this compound its acid quality and provide the electrons for its function as an antioxidant.
What is another name for vitamin C?
A natural water-soluble vitamin (Vitamin C).
Why does vitamin C dissolve in water chemistry?
Vitamin C is soluble in water because it has many opportunities to form hydrogen bonds, and dipole-dipole interactions, with solvent water molecules. Vitamin C does not dissolve in non-polar solvents like hydrocarbons or fats, vitamin C is said to be insoluble in non-polar solvents.
What type of bonds are likely to be present in vitamin C?
All vitamins are covalently bonded molecules. Most of them are commonly named with a letter, although all of them also have formal chemical names. Thus vitamin A is also called retinol, vitamin C is called ascorbic acid, and vitamin E is called tocopherol.
Is vitamin C contains a ketone functional group?
If a molecule has a double bond, it has an alkene functional group. Vitamin C has one alkene functional group.
Is vitamin C soluble in ethanol?
The solubility of l-(+)-ascorbic acid decreases in the order of water, methanol, ethanol, propan-2-ol, tetrahydrofuran, acetone, acetonitrile, and ethyl acetate. Ascorbic acid is a polar organic molecule of the general formula of C6H8O6.
Why are vitamins considered organic compounds?
Vitamins are organic compounds (meaning they contain Carbon) and they are vital nutrients that organisms require in limited amounts. Just like other essential nutrients, vitamins must be obtained from the diet since the organism can not make them (or can not make enough of them) for survival.
Why are vitamins considered as organic substances?
Vitamins are organic substances, which means they’re made by plants or animals. Minerals are inorganic elements that come from soil and water, and are absorbed by plants or eaten by animals. Your body needs larger amounts of some minerals, such as calcium, to grow and stay healthy.
In general, vitamins are coenzymes, or parts of enzymes, that function to assist a specific enzyme to catalyze (increase the rate of) a reaction. Some vitamins are fat soluble and others are water soluble. Fat-soluble vitamins are probably the most common vitamins for some people.
What pH is vitamin C?
It forms a clear colorless to slightly yellow solution. It has two p K a values: 4.2 and 11.6. The pH of a 5% (w/v) solution in water is 2.2–2.5 .
Is vitamin C citric acid?
They are often confused with one another because of their similar names and similar sources of origin, however, ascorbic acid and citric acid are not the same. Ascorbic acid is vitamin C and citric acid is an acidic antioxidant.
Why is it called vitamin C?
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 is the natural form of vitamin C?
Ascorbic acid is the form of vitamin C found naturally in food.
Which is not true about vitamin C?
Vitamin C (ascorbic acid) is a water-soluble vitamin that helps to repair and regenerate tissues, protect against heart disease. So, It is a fat-soluble vitamin is a false statement.
When did humans stop making vitamin C?
About 61 million years ago, some mammals and primates, including our human ancestors, lost the ability for this endogenous vitamin C synthesis .
Is vitamin C in water a chemical reaction?
Ascorbic acid is vitamin C, it’s just the chemical name. As the name says, vitamin C is an acid. This means that if you add ascorbic acid to water it will turn the water slightly sour, the pH-value will drop below 7. It does so (as does any acid) by increasing the concentration of proton (H+) in the water.
Can I dissolve vitamin C in water and drink it?
Vitamin C is a water-soluble vitamin. That means it can dissolve in water. It’s found in many fruits and vegetables and is a popular supplement.
What is vitamin C solubility?
Vitamin C is a water-soluble vitamin. It is needed for normal growth and development. Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine.
Is vitamin C covalent or ionic?
Vitamin C is a covalent compound with the molecular formula C6H8O6. The recommended daily dietary allowance of vitamin C for children aged 4–8 years is 1.42 × 10−4 mol.
Which one of the following functional groups is found in alcohols?
For example, an alcohol is an organic compound with a hydroxyl (-OH) functional group on an aliphatic carbon atom.
Which of the following functional groups is present in vitamin?
Vitamin A is a fat-soluble vitamin and an essential nutrient for humans. It is a group of organic compounds that includes retinol, retinal (also known as retinaldehyde), retinoic acid, and several provitamin A carotenoids (most notably beta-carotene [β-carotene]).
What is the main function of vitamin C?
