4 Major classes of Biomolecules

Zucker --> Polysaccharide

Fettsäuren --> Fette, Lipide, Membranen

Aminosäuren --> Proteine

Nucleotide --> Nucleinsäure

(Bausteine der Zelle --> Makromolekulare Bestandteile der Zelle)

Positive Inone nennt man ...

(Z.B. Na+)

Kationen

Negative Inone nennt man...

(Z.B. Cl-)

Anionen

Gut in Wasser löslich

Wasser liebend

hydrophil

Wasser abstossend

im Wasser unlöslich

Hydrophob

Sugars are also called...

Carbohydrates

Name clases and functions of Sugars

- mono-, di-, oligo-, polysaccharides

- energy source (glucose)

-energy storage (glycogen, starch)

- carbon source

- structure / protection

- recognition/ signaling

Was ist die Hauptenergiequelle der Zelle?

Das Monosaccharide Glucose

Generelle Form der Monosaccharides?

(CH2O)n  wobei n=3,4,5,6

z.B. (CH2O)n  ribose

Monosaccharides- Disaccharides

entstehung? / Umwandlung?

Siehe Bild!

What are isomers?

Same chemical formulas, different structures

what is Lactose?

Disaccarides: Glactose in ß(1 -> 4) linkage with glucose

What are the main function of Polysaccarides?

-Energy storage

- structure (e.g. cellulose, chitin)

Generelles über Lipids?

- insouble in water

- souble in organic sovents and other lipids

- very important biomolecules

4 Main classes of Lipids?

  1. Triacylglycerols (TAGs) - storage lipides (non-polar, also known as triglycerides)
  2. Phosphoacylglycerols - Membrane structural lipids (polar)
  3. Sphingolipids - Membrane structural lipides (polar)
  4. Nonsaponifiable lipids

 

Function of Lipids?

  • Storage molecules for energy
  • Structural components of cellular membrane
  • protective molecules (waxes)
  • homones and vitamines
  • intracellular messengers
  • pigments
