The type of polymerization mechanism used depends on the type offunctional groupsattached to the reactants. In the biological context, almost all macromolecules are either completely polymeric or are made up of large polymeric chains. Classification of Polymers ...
While any expression that cites the number and kind of atoms is a chemical formula, there are different types of formulas, including molecular, empirical, structure, and condensed chemical formulas. Molecular Formula Also known as the "true formula," the molecular formula states the actual number ...
Examples of Homologous Chemistry Lesson Summary FAQs Activities Which is the best definition of a homologous series? A homologous series contains homologues that differ by one methylene group. Furthermore, the homologues in a homologous series all have the same functional group. What is a homologo...
involved in the transfer of functional groups from a donor molecule to an acceptor molecule. isomerases – there are 4 different sub-categories under this. they bring about structural changes within the molecule. ligases – an example is dna ligase which catalyzes ligation or repair of breaks in...
The chemistry of its two-part system contributes to this strength. The ability to tolerate a range of alterations is another source of strength. Two-part epoxy involves the mixing of a resin and a hardener to bond. Polymerization, or the chemical reaction that joins monomer molecules together ...
Besides all of the advantages of first generation solar cells, they have great stability and are commercially viable [223]. The main drawback of the first generation solar cell is the high fabrication cost caused by the requirement for high purified silicon [224]. Although many research groups ...
The structure of biological molecules Cells are largely composed ofcompoundsthat contain carbon. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organicchemistryand plays a large role in understanding the basic functions of cells. Because...
Water is found in the extracellular fluids of the body (the blood plasma, the lymph, and the interstitial fluid) and within the cells themselves. It serves as a solvent without which the chemistry of life could not take place. The human body is about 60 percent water by weight. Lipids—...
