, 1 Structuur, eigenschappen en functies van de
biomoleculen
1.1 Chemische samenstelling van de cel (pg.3-4)

grootste deel an de chemicaliën in cellen zijn organische erbindingen.

O ergrote deel an het drooggewicht an een cel bestaat uit macromolecule  90%

Voornaamste functes an de macromoleculen in de cel:

A. Polysacchariden
- reser efuncte (b . Zetmeel, glycogeen)
- structurele functe (b . Cellulose, chitne, mureïne in de celwanden)
B. Lipiden
- reser efuncte (b . Olie- en etdruppels)
- structurele functe (b . Fosfolipiden in membranen)
C. Proteïnen
- enzymen: katalyseren de reactes an het metabolisme
- reser efuncte (b . Albumine)
- structurele functe (b . Collageen)
- regulatorische functe (b . Hormonen)
- bewegingsfuncte (b . Spierbeweging)
- defensie e functe (b . Antlichamen en toxines)
- transportuncte (b . Hemoglobine)
D. Nucleïnezuren
- DNA: genetsch materiaal
- RNA: komt tussen bij de expressie an het genetsch materiaal

Ook anorganische erbindingen in de cel:

Fosfaat, NH4+, Mg2+, Ca2+, K+ en Fe3+  hoge concentrates

Samenstelling bacteriële cel: 70% water
22% macromoleculen
18% precursoren 1

1.2 Het element koolstof in de biochemie (pg.5)
C kan 4 co alente bindingen aangaan met andere atomen (O, P, N, S en H)

Ketens onbeperkte lengte en combinates

combinates nodig oor opbouw en functoneren an een organisme en oor doorge en an
kenmerken

1.3 Polair vs apolair (pg.5-7)
polair Apolair
Hydrofel Hydrofoob
wateraantrekkend Lipofel
wateroplosbaar Waterafstotend
