what are the primary characteristics used to identify a compound as a carbohydrate?

Carbohydrates are organic compounds that are organized as ring structures and are always composed of the elements carbon, hydrogen, and oxygen. Carbohydrates are truly hydrates of carbon because the ratio of hydrogen atoms to oxygen atoms is always nearly 2:1, as in H2O. They also have many functions.

Carbohydrates (carbo- = “carbon”; hydrate = “water”) contain the elements carbon, hydrogen, and oxygen, and only those elements with a few exceptions. The ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1.

Sugar is a compound. It has the chemical formula: C12H22O11. It is a carbon compound and carbon forms covalent compounds (compounds formed by the sharing of electrons between the elements) . So it is not a mixture as the elements (C,O,H) react chemically and are not physically mixed with each other .

Carbohydrates can be classified as monosaccharides, oligosaccharides, and polysaccharides. Monosaccharides are simple carbohydrates containing between three and eight carbon atoms, the most common having five or six. They consist of a single sugar molecule – mono meaning 'one' and saccharide 'sugar'.

The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses. Glucose energy is stored as glycogen, with the majority of it in the muscle and liver.

Carbohydrates, also known as saccharides or carbs, are sugars or starches. They are a major food source and a key form of energy for most organisms. They consist of carbon, hydrogen, and oxygen atoms.

Sugar is comprised of carbon, oxygen and hydrogen, which are organized into single units. Sugars contain just one or two of these units and are therefore “simple”. Starches and fibers have many units of sugar, making them more “complex”. So all starches are carbohydrates, but not all carbohydrates are starches.

Chemical composition and structure: Carbohydrates are polymers of monosaccharides, which are polyols (many OH groups) with an aldehyde or ketone functional group. Fats are esters of fatty acids and glycerol. Most carbohydrates are hydrophilic, smaller ones are soluble in water. Fats are hydrophobic.

There are five primary functions of carbohydrates in the human body. They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism.

Carbohydrates are organic compounds such as sugars and starches. They provide energy and form structures such as cell walls. Lipids are organic compounds such as fats and oils. They store energy and help form cell membranes in addition to having other functions in organisms.

The physical properties of carbohydrates depend primarily on their microsac- charide composition, glycosidic linkage, functional groups present, molecular size and branching [1].

The two main forms of carbs are: simple carbohydrates (or simple sugars): including fructose, glucose, and lactose, which also are found in nutritious whole fruits. complex carbohydrates (or starches): found in foods such as starchy vegetables, whole grains, rice, and breads and cereals.

Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharides—sucrose, lactose, and maltose—have 12 carbon atoms, with the general formula C12H22O11.

Carbohydrates are hydrophilic substances which are soluble in water and alcohol. The -OH groups of carbohydrates are primarily responsible for their solubility. The solubility of glucose is examine in this experiment.
