Macro molecules A macromolecule is a very large molecule commonly created by polymerization of smaller subunits. In biochemistry‚ the term is applied to the three conventional biopolymers (nucleic acids‚ lipids‚ proteins and carbohydrates)‚ as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles. The individual constituent molecules of macromolecules are called monomers(mono=single‚ meros=part). Usage The term macromolecule was coined by Nobel laureate Hermann

CH 202 Breakdown UV/Vis: Molecules containing π-electrons or non-bonding electrons (n-electrons) can absorb the energy in the form of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. The more easily excited the electrons (i.e. lower energy gap between the HOMO and the LUMO)‚ the longer the wavelength of light it can absorb. Conjugation raises the energy of the bonding orbitals and lowers the energy of the antibonding molecular orbital. This

most waters that humans are drinking are purified‚ most tap and bottled water has 10 to 20 molecules per water cluster. The larger the molecular water cluster‚ the lower the electron activity. The smaller the molecular water cluster‚ the higher the electron activity. The reason that there is greater electron activity surrounding the smaller water cluster is because as one decreases the number of water molecules that are clustering‚ one increases the surface area that can now express its charge. Currently

Polymers are chains of monomers (atom or a small molecule that has the potential of chemically binding to other monomers of the same species) which link in various fashions (e.g. cross-link‚ linear linking) to form materials that are used constantly to help humanity’s comfort and existence thrive.

A hydrate is any compound that contains water in the form of H2O molecules and usually has a definite content of water by weight. Hydrates typically have a crystal like appearance that can vary in colour and have a naming scheme based on the compound and number of water molecules that are in the hydrate. Copper(II) sulfate pentahydrate‚ or CuSO4 * 5H2O‚ is a ratio of one copper sulfate to five (penta) molecules of water. Copper sulfate pentahydrate is a blue hydrate while anhydrous copper sulfate
