Porozum\u011bn\u00ed bun\u011b\u010dn\u00e9 a molekul\u00e1rn\u00ed biologii se v posledn\u00ed dob\u011b v\u00fdrazn\u011b roz\u0161\u00ed\u0159ilo.

Jedn\u00edm z t\u011bchto prob\u00edhaj\u00edc\u00edch v\u011bdeck\u00fdch pokrok\u016f je design molekul. V tomto \u010dl\u00e1nku se jednoduch\u00fdm a dynamick\u00fdm zp\u016fsobem dozv\u00edte v\u00edce o n\u00e1vrhu molekul a jeho hlavn\u00edch \u00fa\u010delech.<\/p>\n\n\n\n

Co je to molekula?<\/h2>\n\n\n\n

Molekula je skupina dvou nebo v\u00edce atom\u016f, kter\u00e9 dohromady tvo\u0159\u00ed nejmen\u0161\u00ed rozpoznatelnou jednotku, na kterou lze rozd\u011blit \u010dist\u00fd materi\u00e1l p\u0159i zachov\u00e1n\u00ed jeho obsahu a chemick\u00fdch vlastnost\u00ed. Molekuly se ozna\u010duj\u00ed symbolem prvku a indexem ud\u00e1vaj\u00edc\u00edm po\u010det atom\u016f.<\/p>\n\n\n\n

Diatomick\u00e9 molekuly vznikaj\u00ed, kdy\u017e se spoj\u00ed pouze dva atomy. Oxid uhelnat\u00fd (CO) je dvouatomov\u00e1 molekula slo\u017een\u00e1 z jednoho atomu uhl\u00edku a jednoho atomu kysl\u00edku. Homojadern\u00e1 diatomick\u00e1 molekula vznik\u00e1, kdy\u017e se spoj\u00ed dva atomy naprosto stejn\u00e9ho prvku, nap\u0159\u00edklad kysl\u00edku (O2) a dus\u00edku (N) (N2). V\u00edceatomov\u00e9 molekuly, jako je voda (H2O) a oxid uhli\u010dit\u00fd, obsahuj\u00ed v\u00edce ne\u017e dva atomy (CO2). Polymery jsou v\u011bt\u0161\u00ed molekuly, kter\u00e9 mohou obsahovat tis\u00edce atom\u016f.<\/p>\n\n\n\n

Atomy se jako molekuly mohou skl\u00e1dat r\u016fzn\u00fdmi zp\u016fsoby. Kombinac\u00ed stejn\u00fdch atom\u016f v r\u016fzn\u00fdch mno\u017estv\u00edch m\u016f\u017ee vzniknout n\u011bkolik molekul. Voda (H2O) je tvo\u0159ena dv\u011bma atomy vod\u00edku a jedn\u00edm atomem kysl\u00edku, zat\u00edmco peroxid vod\u00edku je tvo\u0159en dv\u011bma atomy vod\u00edku a dv\u011bma atomy kysl\u00edku (H2O2). A stejn\u00e9 atomy se mohou kombinovat ve stejn\u00e9m pom\u011bru, ale v r\u016fzn\u00e9 fyzik\u00e1ln\u00ed struktu\u0159e. Fyzik\u00e1ln\u00ed struktura molekuly ur\u010duje jej\u00ed vlastnosti. <\/p>\n\n\n\n

N\u00e1vrh molekuly<\/h2>\n\n\n\n

N\u00e1vrh molekuly je in\u017een\u00fdrsk\u00e1\/v\u011bdeck\u00e1 konstrukce, kter\u00e1 kombinuje dv\u011b nebo v\u00edce slo\u017eek za \u00fa\u010delem vytvo\u0159en\u00ed nov\u00e9 biologick\u00e9 l\u00e1tky.<\/p>\n\n\n\n

Ve farmaceutick\u00e9m pr\u016fmyslu je design molekul cenn\u00fdm p\u0159\u00ednosem. Kdykoli je uveden na trh nov\u00fd l\u00e9k proti rakovin\u011b, znamen\u00e1 to \u00fasil\u00ed v\u011bdc\u016f, kte\u0159\u00ed str\u00e1vili roky pr\u00e1ce v z\u00e1kulis\u00ed, aby vytvo\u0159ili a otestovali nov\u00fd design molekuly.<\/p>\n\n\n\n

\u00da\u010delem \u00fapravy designu molekuly je, aby byl l\u00e9k co nej\u00fa\u010dinn\u011bj\u0161\u00ed a z\u00e1rove\u0148 bezpe\u010dn\u00fd a jednoduch\u00fd na v\u00fdrobu.
