Topics related to "macromolecule"

macromolecule
macromolecule term that may refer either to a crystal such as a diamond, in which the atoms are identical and held by covalent bonds (see chemical bond ) of equal strength, or to one of the units that compose a polymer . Macromolecules such as proteins and nucleic acids are vital to the functio... Read more
pinocytosis
pinocytosis A form of endocytosis in which the material enclosed is a liquid and there is no fusion with a lysosome. Pinocytosis may be a means by which macromolecules (e.g. hormones and proteins) are taken into a cell.... Read more
molecular biology
molecular biology scientific study of the molecular basis of life processes, including cellular respiration, excretion, and reproduction. The term molecular biology was coined in 1938 by Warren Weaver, then director of the natural sciences program at the Rockefeller Foundation. In 1950 W. T. Astbur... Read more
dialysis
dialysis , in chemistry, transfer of solute (dissolved solids) across a semipermeable membrane. Strictly speaking, dialysis refers only to the transfer of the solute; transfer of the solvent is called osmosis . Dialysis is frequently used to separate different components of a solution. For example,... Read more

Mitochondria
Encyclopedia entry from: Encyclopedia of Aging ...In 1956, Denham Harman first proposed that free radicals play a major role in the aging process by causing cumulative macromolecule damage. Harman subsequently extended his theory and proposed that mitochondria are the major players in aging, since mitochondria...
