polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids.
What is a polymer easy definition?
: a chemical compound that is made of small molecules that are arranged in a simple repeating structure to form a larger molecule. polymer. noun. poly·mer | ˈpäl-ə-mər
What is a polymer and example?
There are two types of polymers: synthetic and natural. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
What is a polymer in biology A level?
Polymers are long chains that are composed of many individual monomers that have been bonded together in a repeating pattern. Condensation Reactions occurs when two molecules combine to form a more complex molecule with the removal of water.
What is a polymer in very short answer?
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester. The term polymer is often used to describe plastics, which are synthetic polymers.
What is polymers in materials science?
A polymer (the name means “many parts”) is long chain molecule made up many repeating units, called monomers. Polymers can be natural (organic) or synthetic.
How do you explain polymers to a child?
Polymers are very big molecules made up of many smaller molecules layered together in a repeating pattern. In fact, the word polymer is Greek for ‘many parts. ‘ The smaller molecules that come together to form polymers are called monomers–small units that link together over and over to form a large polymer.
What is a monomer in biology?
monomer, a molecule of any of a class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers. The essential feature of a monomer is polyfunctionality, the capacity to form chemical bonds to at least two other monomer molecules.
Which is an example of a biological polymer?
Starch and cellulose are biological polymers which are made by plants. The monomers for both starch and cellulose are sugar molecules. Cellulose is used to make the strong cell wall which gives plant cells (and therefore plants) strength.
What is a monomer and polymer in biology?
Monomers are the smaller units from which larger molecules are made. Polymers are molecules made from a large number of monomers joined together. Monosaccharides, amino acids and nucleotides are examples of monomers.
What is a polymer in biology quizlet?
Polymer. a long molecule consisting of many similar or identical building blocks linked by a dehydration reactions.
Is DNA a polymer?
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. The sugar and phosphate create a backbone down either side of the double helix.
What is polymer short answer Class 8?
A polymer is a very big molecule formed by the combination of a large number of small molecules. The small molecules which join together to form a polymer is called monomer.
What is polymer answers?
A polymer is a large molecule composed of repeated monomer units. Answer: A polymer is chemical compound where molecules are bonded together in long repeating chains. These materials, polymers, have unique properties and can be tailored depending on their intended purpose.
Is polymer A plastic?
Plastics are a group of materials, either synthetic or naturally occurring, that may be shaped when soft and then hardened to retain the given shape. Plastics are polymers. A polymer is a substance made of many repeating units.
