    Abstract : En sjukdom kan många gånger härledas till en kaskadereaktion mellan proteiner, co-faktorer och substrat. Denna kaskadreaktion blir många gånger målet för att behandla sjukdomen med läkemedel. För att designa nya läkemedelsmoleyler används vanligen datorbaserade verktyg. READ MORE

    Abstract : Popular Abstract in Swedish Hemoglobin, det protein som transporterar syre i blodet är förmodligen det mest välkända proteinet. Det är ett av många exempel på porfyrinproteiner, dvs. proteiner med en porfyrinring i det aktiva centrat. Porfyrinen kan binda en metalljon i mitten av ringen. READ MORE

    Abstract : Popular Abstract in English Proteins are a big biological molecules that help cells to function. Proteins play important roles in all vital processes of the living cell, transporting molecules, speeding up chemical reactions, supporting structure of other proteins and the cell, helping the cell to move. Various disease-causing agents (e.g. READ MORE
