in the animated nature come useful only linksgedrehte Aminosäuren to (Doppelhelix, organische Enzyme etc.): such "Linksdrehenden" Eiweisse having itself evident to rechtsgedrehten durchgesetzt! biochemist and Pharmakologen rauften itself former z.B. often The hairs, because the analysis the begot Medikamentenwirkstoffes showed, that the Herstellungsformel very eingehalten watts, but the stuff nevertheless not gewirkt has. then was is again happens, that the rechtsdrehende Eiweiss-Variante arose, The biologisch completely unwirksam remaining.

The anfängliche chance, that left- or rechtsdrehendes stuff arise, is 50:50 (at least if The Ausgangssuppe not 'vorgeimpft' watts). but wieso? (One ähnliches trouble throws The question on, Why it in the known universe particularly matter and hardly Antimaterie gives, where still The initial position sure symmetrisch was?). The response sounds "Symmetriebruch" - but the describe well sooner the Result, as the it at understanding helps. therefore the following Progi, inspired of a chapter from "Zahl, Time, Zufall" of Prof. Rudolf Taschner.

Importent Nachtrag To supra: further Literaturstudium shows uneinheitliche terms: in the deutschsprachigen space finds one The Bezeichnung "L-Aminosäure" and "R-Aminosäure". thereby shining The "technische Schraubrichtung" the Moleküls along its Hauptachse meant To his.
in the anglophilen specialized literature knows one against it The Bezeichnungsvorsätze "L-" for rechtsdrehend (!) and "D-" for linksdrehend, where but the impact on The Polarisationsebene polarisierten Lichtes meant is. thereby are The "rechtsdrehenden" L-Moleküle The biologisch effective!
