Chemical Building Blocks of Life
Chemical Bonds
Ionic Bonds
transfer electrons
form ions
create salts
relationship → salts dissolve in water
Covalent Bonds
share electrons
strong, stable bonds
build molecules
Covalent bonds form when atoms share electrons, creating stable molecules that make up living organisms.
Hydrogen Bonds
weak attraction
hold water molecules together
stabilize DNA structure
Inorganic Molecules
Water (H₂O)
polar molecule
universal solvent
supports chemical reactions
regulates temperature
Water is vital because it transports substances, regulates body temperature, and allows chemical reactions to occur.
Acids
release H⁺ ions
lower pH
Bases
accept H⁺ ions
raise pH
Salts
formed from ionic bonds
dissolve into ions in water
Organic Macromolecules
Carbohydrates
quick energy source
example: glucose
Lipids
long-term energy storage
insulation
main component of cell membranes
Proteins
structure & function
made of amino acids
include enzymes
Nucleic Acids
DNA
RNA
store genetic information
Enzymes & Chemical Reactions
enzymes are proteins
biological catalysts
lower activation energy
substrate specific
speed up reactions
Enzymes help chemical reactions occur faster, allowing normal body functions without being consumed during the process.
