WebDNA 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. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). WebCellulose and starch (two types of carbohydrate) are also natural polymers made up of glucopyranose monomer bonded together in different ways. Rubber is a mixture of polymers. Plastics are man-made polymers. Many fibers are made of polymers. If the "units" called monomers in a polymer are all the same, then the polymer is called a "homopolymer".

WebApr 9, 2024 · Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers. The polymer is more than the sum of its parts: it acquires new characteristics, and leads to an osmotic pressure that is much lower than that formed by its ingredients; this is an important advantage in the maintenance of … WebOct 29, 2024 · It is also the simplest polymer, consisting of random-length (but generally very long) chains made up of two-carbon units.

WebNucleic acids are polymers. This means that they are large molecules that are made up of several repeating molecular subunits, or monomers. The monomers of nucleic acids are called nucleotides. A nucleotide is made of three parts: a phosphate group, a pentose sugar, and a nitrogen-containing base. WebIn this article the molecules of the polymers discussed generally have a degree of polymerization (the number of repeat units in the polymer molecule) of more than 30.
