Polymers are large molecules made up of many smaller subunits. Did you know… We have over 220 college The modern understanding of polymers as macromolecules was proposed by German organic chemist Hermann Staudinger (1881–1965) in 1920. The sequence of bases along a DNA or mRNA polymer is unique for each gene. For carbohydrates, the monomers are monosaccharides. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. Different types of monomers can combine in many configurations, giving rise to a diverse group of macromolecules. Get the unbiased info you need to find the right school.

In evolutionary biology, abiogenesis, or informally the origin of life (OoL), is the natural process by which life has arisen from non-living matter, such as simple organic compounds. poly(ethene) is the polymer; The C=C double bond in ethene is involved in the polymerisation reaction. The process of vulcanizing rubber by adding sulfur and applying heat was described by British engineer Thomas Hancock (1786–1865) in 1843 (UK patent) and American chemist Charles Goodyear (1800–1860) in 1844. Synthetic polymers are used to make plastics, adhesives, paints, mechanical parts, and many common objects. Carbohydrates are naturally produced by plants.. carbohydrate substances (sugars, starches, etc.) they are pleomorphic; They are mostly globular or granular in appearance. The first man-made plastic was nitrocellulose. Like humans and animals, plants are also composed of several cells.
