В роботi за допомогою методу спектроскопiї з роздiленням в часi проведено дослiдження фотоциклу мембранного бiлка бактерiородопсину в залежностi вiд концентрацiї холестерину в мембранi дипальмiтоїфосфатидилхолiну (ДПФХ). Показано, що температурнi залежностi констант швидкостей переходiв бактерiородопсину мiж промiжними станами задовольняють рiвняння Ейрiнга. Доведено, що додавання холестерину в мембрану ДПФХ приводить до прискорення фотоциклу бактерiородопсину.
