WebNov 27, 2024 · There are four basic kinds of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids. These polymers are composed of different monomers and serve different functions. Carbohydrates: molecules composed of sugar monomers. They are necessary for energy storage. Carbohydrates are also called saccharides and … WebA polymer is a large molecule, or macromolecule, composed of small repeating singular molecular structural units called monomers. The repeating molecular units are joined together chemically through covalent bonds. The word polymer comes from the Greek “poly” (many) and “meros” (part).

WebSep 14, 2024 · Biological macromolecules generally are polymers, (poly = many; mer = unit), formed by joining monomers, or single molecules, together in a long chain. They are formed by the process of polymerization. In this process, dehydration synthesis, or the removal of a water molecule, joins two monomers together (Figure 2.8). WebA dehydration reaction (or condensation reaction) is the process in which _____. a. the bonds between the individual monomers of a polymer are broken by the addition of water molecules b. water molecules are used as a source of raw material to break down polymers to monomers c. water molecules are attracted to each other d. water molecules are …
WebPolymers are broken down into monomers via hydrolysis reactions, in which a bond is broken, or lysed, by addition of a water molecule. During a hydrolysis reaction, a molecule composed of multiple subunits is split in two: one of the new molecules gains a hydrogen atom, while the other gains a hydroxyl (-OH) group, both of which are donated by water.
