What is the structure of a carbohydrate molecule?
A carbohydrate is a naturally occurring compound, or a derivative of such a compound, with the general chemical formula Cx(H2O)y, made up of molecules of carbon (C), hydrogen (H), and oxygen (O). Carbohydrates are the most widespread organic substances and play a vital role in all life.
What best describes the structure of carbohydrates?
Terms in this set (14) Which of the following best describes the structures of carbohydrates? They occur as monomers, chains of monomers, and branched structures.
What is the structure and function of carbohydrates?
In Summary: Structure and Function of Carbohydrates Carbohydrates are a group of macromolecules that are a vital energy source for the cell and provide structural support to plant cells, fungi, and all of the arthropods that include lobsters, crabs, shrimp, insects, and spiders.
What is the structure of simple carbohydrates?
Simple carbohydrates contain the monosaccharide and disaccharide groups. Monosaccharides are comprised of a single simple sugar unit, glucose, fructose, or galactose, and they cannot be broken down into simple sugar units. These three monosaccharides are combined in various ways to make more complex carbohydrates.
What is carbohydrate discuss its structure and classification?
Monosaccharides are simple sugars. They cannot be hydrolyzed into a simpler form. The simplest carbohydrates are the three-carbon dihydroxyacetone and trioses glyceraldehyde. They are further classified into glucose, fructose, galactose, and mannose….Classification of carbohydrates.
| Aldoses | Ketoses | |
|---|---|---|
| (C6H12O6) Hexoses | Glucose | Fructose |
Do carbohydrates provide structure?
What is monosaccharides and its structure?
Monosaccharides are the simplest unit of carbohydrates. They’re composed of carbon, hydrogen, and oxygen atoms, and they cannot be broken down further since they are already in their simplest form. Their general formula is (CH2O)n, where n is any number equal or greater than 3.
What are the 3 classifications of carbohydrates?
There are three main types of carbohydrates:
- Sugars. They are also called simple carbohydrates because they are in the most basic form.
- Starches. They are complex carbohydrates, which are made of lots of simple sugars strung together.
- Fiber. It is also a complex carbohydrate.
How do you describe a carbohydrate?
Carbohydrates, or carbs, are sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks. Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs.
What is the the formula of a carbohydrate molecule?
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term “carbohydrate” is based on its components: carbon (“carbo”) and water (“hydrate”).
What molecule is not considered a carbohydrate?
Simple carbohydrates have longer sugar molecule chains than complex carbohydrates. These sugar molecules are converted into glucose, which the body uses for energy. Complex carbohydrates take longer to break down and have more long-lasting nutrition in the body than simple carbohydrates since their chains are longer.
What is the basic structure of a carbohydrate?
Sugars. They are also called simple carbohydrates because they are in the most basic form.
What molecules are used to make carbohydrates?
– Carbohydrates: molecules composed of sugar monomers. – Lipids: water-insoluble molecules that can be classified as fats , phospholipids, waxes, and steroids. – Proteins: biomolecules capable of forming complex structures. – Nucleic Acids: molecules consisting of nucleotide monomers linked together to form polynucleotide chains.
