Basically, a carbohydrate is a biomolecule composed of a hydrogen and an oxygen atom in a ratio of 2:1. The empirical formula for a carbohydrate is Cmn, where C is carbon and n is the number of hydrogen atoms.


Often called simple sugars, monosaccharides are crystalline water-soluble solids. They contain a central carbon molecule, two hydrogen atoms, and an oxygen atom. The oxygen atom is bonded to the carbon atom through a double bond, called the carbonyl group. These carbohydrates act as structural units, as well as energy-storing molecules.

Monosaccharides are grouped into different categories based on their placement of the carbonyl group. Usually, they contain five or six carbon atoms, but there are some that have as few as three. The carbon atoms are usually placed in a ring-shaped structure. Some monosaccharides can also exist as linear chains, forming oligosaccharides.

The most common monosaccharide is glucose. It is a simple sugar, and is used for energy production and the synthesis of glycogen. Animals use glucose as a major source of energy. Other monosaccharides include fructose, ribose, and maltose. These carbohydrates are found in many fruits. They also are found in honey.

Monosaccharides can also form disaccharides, which are two monosaccharides linked together. Several monosaccharides can form polysaccharides, which are larger complex molecules composed of thousands of monosaccharides. Polysaccharides are produced by plant cells, and are used for structural purposes.


Glucose is a simple monosaccharide with six carbon atoms. It is a product of photosynthesis and is a source of energy for living cells. It is also a precursor for the synthesis of many important substances. It is commonly available as a white substance. It is primarily stored as glycogen in animals and fungi. It is also found in plants and fruits.

A glucose molecule may exist in a ring (cyclic) form or an open chain (acyclic) form. The ring form is a result of a covalent bond between the aldehyde C atom and the C-5 hydroxyl group. It is possible to obtain a ring form by chain cleavage of tetra methyl ether derivatives.

A glucose molecule may also be obtained by hydrolysis of carbohydrates. Typically, these reactions occur at a pH of 4.0 to 4.5. During this process, the carbonyl function of ketose is reduced by sodium borohydride. The hydrolysis process is usually catalyzed by a glucoamylase enzyme from the fungus Aspergillus niger.

Fruits and seeds

Whether you're a vegan, vegetarian or just a healthy eater, it's important to consume a variety of carbohydrates. Carbohydrates are the building blocks of your body's energy supply. They contribute to your digestive health, heart health, energy and weight loss. However, eating too much carbohydrates can have a negative impact on your health.

Fortunately, a variety of plant-based foods contain carbohydrate. Fruits and seeds are two examples. These types of foods are a good source of fiber, which can help regulate blood sugar.

Fruits and seeds are also a source of vitamins and minerals. Many of them contain antioxidants, which can help protect your body against disease. Fiber-rich vegetables can help lower cholesterol, while also preventing stomach problems. They also contribute to your health by helping you feel full.

Fruits and seeds are an important part of a plant-based diet. They can be eaten by themselves or combined with other foods. Some seeds have high amounts of protein. Adding nuts to your oatmeal or trail mix can help you achieve your daily carbohydrate needs.

Starchy and non-starchy vegetables

Whether you're following a low carb diet, or just want to improve your health, it's important to eat enough starchy and non-starchy vegetables. These foods contain high amounts of fiber, which can help you lose weight, maintain a healthy blood sugar level, and keep your cholesterol in check. They also contain many vitamins, minerals, and phytonutrients.

While starchy vegetables can help you get your carbohydrate needs met, they can also add up quickly. If you're trying to follow a carb-restricted diet, it's a good idea to make sure you fill half of your plate with non-starchy vegetables.

One way to determine if a starchy vegetable will add up to too many calories is to take a look at the glycemic index. Starchy vegetables have a higher glycemic index than non-starchy vegetables, which means they will raise blood glucose levels more quickly. That said, they also have a high fiber content, which can help to offset the calories.

You can also consider how the foods are prepared. Using a healthy cooking method, such as boiling, steaming, or baking, can make a big difference in the nutritional content of the vegetables. Using healthier cooking methods also helps you limit calories, fat, and salt.
