Molecules of Life. Chapter 2 & 3. Water properties. Unique properties based on its structure Oxygen is more electronegative than hydrogen Electrons spend more time with oxygen than with hydrogen Polar covalent bond ie unequal sharing. Water Properties.
Chapter 2 & 3
Slight polar ends
Water molecules “stick” to each other in distinct patterns
resulting in organization of molecules
Water molecules tendency to “stick” to each other
Forms hydrogen bonds in 3-d
Results in surface tensionCohesion
Why is surface tension important…
Don’t wash your car in the creek or dump soap down the storm wash!
Water molecules tendency to “stick” to other polar moleculesAdhesion
In Biology Shape Maters!!
What happens when we add different types of elements to hydrocarbons?
Monosaccharides are rings in aqueous solutions
3 fatty acids
Lower the energy involved in chemical reactions
Speed up chemical reactions
Based on shape
Specific to a reaction
Help chemical reactions occurEnzymes
