October 16, 2013. As additional monomers join via multiple dehydration synthesis reactions, the chain of repeating monomers begins to form a polymer. Complex carbohydrates, nucleic acids, and proteins are all examples of polymers that are formed by dehydration synthesis. What is the monomer of carbohydrates A monomer is one which is a basic carbohydrate molecule. The words come from the Greek language where mono means "one", poly means "many", and meros means "a part". By the removal of an OH group and a hydrogen atom. Complex carbohydrates are formed from monosaccharides, nucleic acids are formed from mononucleotides, and proteins are formed from amino acids. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.

Different types of monomers can combine in many configurations, giving rise to a diverse group of macromolecules. Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers. A feature of monomers is that they have two carbon atoms which are joined, called a carbon double bond. Through a process called polymerization, monomers are are linked together into long repeating chains to form polymers Here's a quick diagram i drew using ms paint to illustrate my point. In order to completely understand the concept of monomers, let us first revise our definition of molecules. The monomer of a protein is an amino acid. The removal of a hydrogen from one monomer and the removal of a hydroxyl group from the other monomer allows the monomers to share electrons and form a covalent bond. Monomers can simply be referred to as smaller sub-units of polymers. In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In the process, a water molecule is formed. the C-H bonds found in carbohydrates store energy. Alkenes can be used to make polymers. This is the reverse of the dehydration synthesis reaction joining these two monomers. And two or more polymers can be combined to produce an alloy, or blend, that displays characteristics of each component. The DNA molecule is technically classified as a bipolymer, which means that it contains two polymer chains that link up to form the larger molecule. There is great diversity in the manner by which monomers can combine to form polymers. b. Thanks for the A2A.

This allows for easy absorption of nutrients by cells in the intestine. Glucose monomers are linked together to form polymers such as starch, glycogen, and cellulose. Monomers like glucose can join together in different ways and produce a variety of polymers. Let us know if you have suggestions to improve this article (requires login).
