The colostral stage is further characterized by high abundance of mRNAs (CTSD, CTSB, PSAP) that encode proteins involved in macromolecule catabolism (Table 3).

They further speculate that these eliminated macromolecules might be regenerated by the cellular machinery of the daughter cell when necessary.

Be it snow on a slope that can sit there for days before being sent descending by an overambitious skier or bonds in macromolecules that change dramatically upon appropriate activation — systems that reside for extended periods of times in one state before switching rapidly to another, energetically more favourable one are found in many different contexts.

As the smallest structural change in the scale of biological world, the isomerization and the catalysis of this reaction by isomerases is of great interest, to bridge the dynamics of chemical bonds and the biological functions of the macromolecules.

In fact, the macromolecules in the CSF are actively transported by the capillary endothelium from brain to blood.

This means that proteins can self - regulate or be regulated by other macromolecules without the need for proximity.

A crystal is really just a very large macromolecule, and could be used for richly varied complex chemistry if assembled atom by atom into desired shapes with strategically placed defects and dopants.

In 2008 he was elected as member of the International Academy of Quantum Molecular Science, whose members are chosen among the scientists of all countries who have distinguished themselves by the value of their scientific work, their role of pioneers or leaders of a school in the broad field of the application of quantum mechanics to the study of molecules and macromolecules.

Tight junctions, regulated by a molecule called zonulin, as well as by conformational changes in the proteins occludin and claudin, are dynamic intercellular structures that modulate the trafficking or passage of macromolecules from the intestinal lumen to the submucosa and into systemic circulation (Fasano, 2012).

In a nut shell, leaky gut syndrome (LGS) describes a condition of altered or damaged bowel lining, caused by antibiotics, toxins, poor diet, parasites or infection can lead to increased permeability of the gut wall to toxins, microbes, undigested food, waste or larger than normal macromolecules.

Emissions of CH4 from most of these sources involve ecosystem processes that result from complex sequences of events beginning with primary fermentation of organic macromolecules to acetic acid (CH3COOH), other carboxylic acids, alcohols, CO2 and hydrogen (H2), followed by secondary fermentation of the alcohols and carboxylic acids to acetate, H2 and CO2, which are finally converted to CH4 by the so - called methanogenic Archaea: CH3COOH → CH4 + CO2 and CO2 + 4H2 → CH4 + 2H2O (Conrad, 1996).
