Pine=Phenylalanine (phe, F) (non-polær)
Timber=Tyrosine (tyr, Y) (polær
Tryp=Tryptophan (trp, W) (non-polær) Desuden den eneste undtagelse med at hvis en sidekæde har oxygen eller nitrogen=polær)

Q

Basiske aminosyre:
Huskeregel, nævn, egenskaber

A

Antal: 3
Huskeregel:
basically, His Lost kid Always returned
Histidine (his, H) Alle sidekæder polære, positive (basiske)
Lysine (lys, K) Egenskaber: Samme som ovenfor
Arginine (arg, R) Egenskaber, samme som ovenfor

Bemærk at histidins sidekæde er klassificeret som værende positiv, men ladningen er ikke tegnet på. Skyldes at den i mange sidekæder har pH 7, så den kan optage proton. Begge måder er korrekte
