Chemistry of Life

Basic Chemistry, Water, Organic Molecules, Energy Changes, Enzymes



What is it
What is it?

  • Matter: Takes up space and has mass

  • Element: Substance that cannot be broken down to other substances by chemical reactions.

  • Compound: Substance consisting of two or more elements in a fixed ration


The most common ones
The most common ones…

  • 25 of 92 natural elements are essential to life

  • C, O, H, N = 96% of all living matter


Elements behavior is due to structure of it s atom
Elements Behavior is due to structure of it’s atom

  • Atomic Particles

  • Atomic Number and Mass

  • Isotopes

  • Behavior due to Valence Electrons


Covalent bonds

Non-polar covalent

Polar covalent

Covalent Bonds


Ionic bonding
Ionic Bonding

  • Salts: Anion & Cation


Other types of bonding

Van der Waals

Other Types of Bonding


Chemical reactions
Chemical Reactions

  • Make and Break Bonds

  • Must remain balanced




Hydrogen bonding
Hydrogen Bonding

  • Cohesion

  • Adhesion

  • Surface Tension

  • Crystaline Solid

  • Solvent

  • Moderation of Temperature

  • Evaporative Cooling


Surface tension
Surface Tension

  • Waters ability to stretch without breaking


Adhesion to matter
Adhesion to matter

  • Capillary action

    • Capillaries in body

    • Xylem in plants


Solid crystal formation
Solid Crystal formation

  • Lattice Structure

  • Density

  • Insulation for bodies of water


Solvent
Solvent

  • Universal solvent

  • Dissolves salts & sugars, vital for life functions





Dissociation
Dissociation

  • Acid / Base

  • Dissociates to form acids or bases

  • Reversable reaction

    • Hydronium

    • Hydroxide


Buffers
Buffers
