P\u0113d\u0113j\u0101 laik\u0101 ir iev\u0113rojami uzlabojusies izpratne par \u0161\u016bnu un molekul\u0101ro biolo\u0123iju. L\u012bdz ar \u0161iem svar\u012bgajiem atkl\u0101jumiem zin\u0101tne s\u0101k virz\u012bties uz priek\u0161u, izstr\u0101d\u0101jot jaunas atbildes uz vec\u0101m probl\u0113m\u0101m.<\/p>\n\n\n\n

Viens no \u0161iem zin\u0101tnes sasniegumiem ir molekulu dizains. \u0160aj\u0101 rakst\u0101 vienk\u0101r\u0161\u0101 un dinamisk\u0101 veid\u0101 uzzin\u0101siet vair\u0101k par molekulu projekt\u0113\u0161anu un t\u0101s galvenajiem m\u0113r\u0137iem.<\/p>\n\n\n\n

Kas ir molekula?<\/h2>\n\n\n\n

Molekula ir divu vai vair\u0101ku atomu grupa, kas kop\u0101 veido maz\u0101ko atpaz\u012bstamo vien\u012bbu, kur\u0101 var sadal\u012bt t\u012bru materi\u0101lu, saglab\u0101jot t\u0101 saturu un \u0137\u012bmisk\u0101s \u012bpa\u0161\u012bbas. Molekulas apz\u012bm\u0113 ar elementa simbolu un apak\u0161indeksu, kas nor\u0101da atomu skaitu.<\/p>\n\n\n\n

Diatom\u0101s molekulas veidojas, kad savienojas tikai divi atomi. Oglek\u013ca monoks\u012bds (CO) ir divatomu molekula, kas sast\u0101v no viena oglek\u013ca atoma un viena sk\u0101bek\u013ca atoma. Homonukle\u0101ra diatomu molekula veidojas, kad savienojas divi viena un t\u0101 pa\u0161a elementa atomi, piem\u0113ram, sk\u0101bek\u013ca (O2) un sl\u0101pek\u013ca (N) (N2). Poliatomu molekulas, piem\u0113ram, \u016bdens (H2O) un oglek\u013ca dioks\u012bds, sast\u0101v no vair\u0101k nek\u0101 diviem atomiem (CO2). Polim\u0113ri ir liel\u0101kas molekulas, kur\u0101s var b\u016bt t\u016bksto\u0161iem atomu.<\/p>\n\n\n\n

Atomi k\u0101 molekulas var veidoties da\u017e\u0101dos veidos. Kombin\u0113jot vienus un tos pa\u0161us atomus da\u017e\u0101dos daudzumos, var veidoties vair\u0101kas molekulas. \u016adens (H2O) veidojas no diviem \u016bde\u0146ra\u017ea atomiem un viena sk\u0101bek\u013ca atoma, savuk\u0101rt \u016bde\u0146ra\u017ea peroks\u012bds veidojas no diviem \u016bde\u0146ra\u017ea atomiem un diviem sk\u0101bek\u013ca atomiem (H2O2). Turkl\u0101t vieni un tie pa\u0161i atomi var apvienoties vien\u0101d\u0101s attiec\u012bb\u0101s, bet ar at\u0161\u0137ir\u012bgu fizik\u0101lo strukt\u016bru. Molekulas fizik\u0101l\u0101 strukt\u016bra nosaka t\u0101s \u012bpa\u0161\u012bbas. <\/p>\n\n\n\n

Molekulu dizains<\/h2>\n\n\n\n

Molekulas dizains ir in\u017eeniertehniska\/zin\u0101tniska konstrukcija, kur\u0101 apvienoti divi vai vair\u0101ki komponenti, lai rad\u012btu jaunu biolo\u0123isku a\u0123entu.<\/p>\n\n\n\n

Pat tad, ja tiek izmantotas metodes, kas paredz ide\u0101las v\u0113lam\u0101s \u012bpa\u0161\u012bbas, \u0137\u012bmi\u0137iem joproj\u0101m katrs modifik\u0101cijas solis ir j\u0101veic manu\u0101li. Tas var aiz\u0146emt ilgu laiku katr\u0101 posm\u0101, un tom\u0113r netiek ieg\u016btas molekulas ar atbilsto\u0161\u0101m \u012bpa\u0161\u012bb\u0101m.<\/p>\n\n\n\n

Viens no veidiem, k\u0101 to izdar\u012bt, ir izmantot datoriz\u0113tu molekul\u0101ro projekt\u0113\u0161anu (CAMD).
