Q

Hydrolyse

A

reactie waarbij water nodig is

17
Q

Sterke interacties

A

Covalente binding = waarbij twee atoomkernen een electron delen
> enzym is nodig voor maken + breken

18
Q

Zwakker interacties

A

Electrostatisch
Water bruggen
Van der Waals
Hydrofobe interactie
(meerdere zwakke = sterk)

19
Q

Van der Waals

A

de afstand waar er een interactie ontstaat tussen twee atoomkernen (zonder fusie)

20

A
  1. H
  2. N
  3. O (O2- in water)
  4. P (DNA)
  5. S (Cysteine en methionine in eiwitten)
  6. Microelementen
