Nucleotide A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.

What type of biological compound is composed of sugar molecules?
A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides.
What type of biological compound is characterized by a carboxylic acid and an amine functional group?
Amino acids are organic molecules that contain an amine functional group (–NH2), a carboxylic acid functional group (–COOH), and a side chain (that is specific to each individual amino acid). Most living things build proteins from the same 20 different amino acids.
What type of biological compound is a polymer of amino acids?
Proteins are polymers made up of strings of amino acids. Proteins serve many functions in organisms including transport of molecules, structure, cell adhesion and as signaling molecules such as hormones.
What class of biological molecules does sugar belong to and what are the most common types of sugars in our diet?
Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides. Monosaccharides (mono- = “one”; sacchar- = “sweet”) are simple sugars, the most common of which is glucose.
What are the types of biological molecules on the basis of molecular weight?
There are four major classes of biological macromolecules ( carbohydrates, lipids, proteins, and nucleic acids ), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass.
What is functional group of carboxylic acid?
A carboxylic acid is an organic compound that has a carboxyl group. The carboxyl group is a functional group that contains a carbon–oxygen double bond and an OH group also attached to the same carbon atom, but it has characteristic properties of its own. Unlike ethers, esters have a carbonyl group.
When an alcohol reacts with a carboxylic acid the major product is a N?
Description: When a carboxylic acid is treated with an alcohol and an acid catalyst, an ester is formed (along with water). This reaction is called the Fischer esterification. Notes: The reaction is actually an equilibrium. The alcohol is generally used as solvent so is present in large excess.
How do you know if a functional group is acidic or basic?
There are two key features of an acidic functional group: the presence of a hydrogen atom that can dissociate from the group (H+), and the ability of the remaining atoms to delocalize the resulting negative charge via resonance.
Is a carbohydrate a monomer or polymer?
A large molecule made of repeating subunits (monomers). For example, a carbohydrate is a polymer that is made of repeating monosaccharides.
What is a polymer in biology?
Polymers are molecules made from a large number of monomers joined together. Monosaccharides, amino acids and nucleotides are examples of monomers. A condensation reaction joins two molecules together with the formation of a chemical bond and involves the elimination of a molecule of water.
What are the three biological molecules?
Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
Is sugar organic or inorganic compound?
Yes, sugars are organic chemicals, which are described as carbon-based compounds with hydrogen. These organic substances can be made by living organisms. They are even employed as a source of energy by living beings. Carbohydrates are chemical compounds that are used to store energy and include sugar and starch.
Which group of organic molecules includes starches and sugar?
Polysaccharides, such as starch, glycogen, cellulose and chitin, contain many sugar molecules linked together.
Why is sugar considered an organic compound?
A carbohydrate is called an organic compound, because it is made up of a long chain of carbon atoms. Sugars provide living things with energy and act as substances used for structure.
