Ik vat in deze samenvatting de sachariden, ook bekend als de suikers, samen. Ik heb het dan over de definitie en de functie, de verschillende indelingen (monosachariden, disachariden, polysachariden) en hun specifieke moleculen.
2. Structuur en functies van suikers, eiwitten en vetten
2.1 Suikers of sachariden
2.1.1 Belang
Sachariden:
- Biochemische verbindingen
- Functie:
- energieleveranciers voor alle levende wezens
- bij planten vormen sachariden structuur van de celwand
- Ribose: nodig om DNA (desoxyribonucleïnezuur) en RNA (robosomaalribonucleïnezuur)
2.1.2 Indeling
C (carbon), H (waterstof), O (zuurstof) verbindingen waarin verhouding aanwezige elementen
= CnH2mOm
➜ valt te verdelen in 3 groepen in functie van hun samenstelling
Belang: - bouwsteen van sommige polysachariden
- belangrijke energiebron (ATP aangemaakt in mitochondriën)
Voorkomen: honing, lichaamsvocht zoals bloed en lymfevocht, sap van rijpe vruchten,...
FRUCTOSE
Belang: levert energie
Voorkomen: vruchten en honing
GALACTOSE
Belang: levert energie
Voorkomen: gevormd na vertering van lactose of melksuiker
RIBOSE
Belang: bouwsteen van RNA en DNA
