Hydrofobe interaktioner Når to upolære molekyler interagere med hinanden.

Antimikrobielle peptider(AMP) Stof bestående af 12-50 aminosyrer, der indgår i det uspecifikke immunforsvar, der for det meste angriber mikroorganismer på forskellige måder vha. α-helix AMP, β-hairpin AMP eller Defensiner.
α-helix AMP AMP gruppe der borer sig ind i cellemembranen på bakterier og hæmmer elektrontransportkæden, hvilket virker til at bakterien løber tør for ATP. Har struktur som en skrue.
β-hairpin AMP AMP gruppe der aktiveres ved en infektion og får fremmede celler til at lysere.
Defensiner AMP gruppe, som virker på forskellige måder fx ved at hæmme vigtige processer (DNA- og RNA-syntese.)
Vaccine Når man sprøjter svækkede organismer eller dele af dem ind i kroppen, så b-huskecellerne husker det antistof der blev brugt og hurtigt kan reagere og producere det rigtige antistof næste gang man bliver inficeret med samme sygdom.
Antibiotika Antibiotika er et lægemiddel der virker imod bakterier. Penicillin er det mest brugte antibiotikum, men der findes også andre. Antibiotika kan både være dræbende eller hæmmende.
Infektionssygdomme Sygdomme der skyldes infektion af patogene organismer.
Antiviral-medicin Antiviral-medicin er ligesom antibiotika, men virker imod virus. Dog er det ikke lige så effektiv som antibiotika er på bakterier.
