What is the molecular structure of carbohydrates?

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 are the 3 structures of carbohydrates?

Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.

Which structure is not a carbohydrate?

Which molecule is not a carbohydrate? A lipid is a hydrophobic polymer, not a carbohydrate.

What are the different structures of carbohydrates?

Carbohydrates are “hydrates of carbon” and have the generic structure of C(n)H(2n)O(n). A single sugar unit is a monosaccharide. These can consist of 3-carbon moieties (triose), 4-carbon units (tetrose), 5-carbon moieties (pentose), and 6-carbon moieties (hexose).

What best describes the structure of carbohydrates?

Which of the following best describes the structures of carbohydrates? They occur as monomers, chains of monomers, and branched structures. The carbohydrates have different properties because they have different arrangements of carbon, hydrogen, and oxygen atoms.

What are the two types of carbohydrates?

What Are Carbohydrates? There are two major types of carbohydrates (or carbs) in foods: simple and complex.

How to draw the structure of a carbohydrate molecule?

There are several ways to draw the structure of carbohydrate molecules. The Fischer projection (straight chain) makes it appear that the molecule is flat but it is a three-dimensional molecule.

Which is the stoichiometric formula for carbohydrates?

Carbohydrates can be represented by the stoichiometric formula (CH 2 O) n, where n is the number of carbons in the molecule. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules.

How are the three types of carbohydrates classified?

This formula also explains the origin of the term “carbohydrate”: the components are carbon (“carbo”) and the components of water (hence, “hydrate”). Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.

Which is the enantiomer of a carbohydrate molecule?

Each carbohydrate molecule also has an enantiomer and the two are designated as the D- and L- versions of the compound. The designation is based on the orientation of the − OH group on the chiral carbon farthest from the aldehyde or ketone.

What is the molecular structure of carbohydrates? 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).
