In addition, surgical implants such as bone reinforcements and replacements ( e . g . hip sockets and cranial plates ) are made with special alloys formulated to resist corrosion, mechanical wear, and biological reactions " in vivo ".

Exploiting the extraordinary efficiency and speed of biological reactions, he translated a difficult mathematical problem into the language of molecular biology and solved it by carrying out a reaction in one-fiftieth of a teaspoon of solution in a test tube.

In the biological reaction, a proton transference to the pyrophosphate ( PPi ) molecule could minimize negative charge accumulation even though the pKa for PPi is 9 . Lys26, His105, and Lys103 are candidates for this transference to the ? phosphate position.

The limited number of different building blocks of RNA ( 4 nucleotides vs > 20 amino acids in proteins ), together with their lack of chemical diversity, results in catalytic RNA ( ribozymes ) being generally less-effective catalysts than proteins for most biological reactions.

Accordingly, while the connection between nicotine and appetite suppression, as well as other physiological responses to nicotine consumption, has been established, whether these chemical and biological reactions translate to smokers being thinner than nonsmokers ( at least concerning certain age groups ), is still debated.

The model, described in an article in the current issue of the journal Nature, is based on the mathematical idea that " self-organizing " systems influenced by just a few basic principles can spontaneously develop complex patterns _ a phenomenon seen in many chemical, physical and biological reactions.

Kervran said that enzymes can facilitate biological transmutations using the weak nuclear force, by what he called " neutral currents . " His response to criticism was to claim that physical laws do not apply to biological reactions, which contradicts the mainstream view that physical laws apply for all scales and conditions.

Generation of sequences of ultrashort optical pulses is key in realizing ultra high speed optical networks, Optical Code Division Multiple Access ( OCDMA ) systems, chemical and biological reaction triggering and monitoring etc . Based on the requirement, pulse shapers may be designed to stretch, compress or produce a train of pulses from a single input pulse.

In a biological context chlorine behaves similarly to other atoms in the halogen chemical series, and thus reductive dechlorination can be considered to fall within a somewhat broader class of biological reactions known as reductive dehalogenation reactions, in which the removal of a halogen substituent from an organic molecule occurs with a simultaneous addition of electrons to the molecule.
