  • Interesting fact: In 1815 French chemist Michael Eugene Chevreul realized the first link between diabetes and sugar metabolism when he discovered that the urine of a diabetic was identical to grape sugar.
    • Metabolism The act or process, by which living tissues or cells take up and convert into their own proper substance the nutritive material brought to them by the blood, or by which they transform their cell protoplasm into simpler substances, which are fitted either for excretion or for some special purpose, as in the manufacture of the digestive enzymes. Hence, metabolism may be either constructive (anabolism), or destructive (catabolism).
    • Metabolism (Biol) The series of chemical changes which take place in an organism, by means of which food is manufactured and utilized and waste materials are eliminated.

    • n metabolism In theology, the consensus of views of some of the early fathers in regard to the eucharist, favoring an objective union of the sensible with the supersensible, or the real with the symbolical presence.
    • n metabolism In poetry, a change from one meter into another.
    • n metabolism In entomology, metamorphosis; transformation; metaboly; transition from larva to pupa, or from pupa to imago.
    • n metabolism In biology: The sum of the chemical changes within the body, or within any single cell of the body, by which the protoplasm is either renewed or changed to perform special functions, or else disorganized and prepared for excretion. Thus, the formation of the colorless blood-corpuscles, the elaboration of the digestive ferments, and the breaking up of proteids into urea and other products are examples of metabolism. Compare anabolism, catabolism.
    • n metabolism Especially, retrograde metamorphosis; catabolism.

In science:

It is suggested that the degree distribution for networks of the cell-metabolism for simple organisms reflects a ubiquitous randomness.
The Blind Watchmaker Network: Scale-freeness and Evolution
This implies that the evolutionary pathway of the cellmetabolism, when projected onto a metabolic network representation, has remained statistically random with respect to a complete set of network states.
The Blind Watchmaker Network: Scale-freeness and Evolution
We demonstrate that the empirically observed degree distributions for networks of the cellular metabolism for simple organisms are good approximations of this random structure.

And greigite’s metabolic potential plays a key role in the mound scenario of Russell and coworkers-an expansion of which is suggested for including magnetism.
Magnetism, FeS colloids, and Origins of Life
At the same time, such a magnetic albeit locally confined ancestor, maintained close-toequilibrium, would also have the potential for coupling with non-equilibrium energy sources (such as pH or redox gradient) -the ’metabolic’ wing of lifeproducing energy rich molecules (Russell and Arndt 2005).
