Lipids
-Composition
-Composition of fats
-Composition of phospholipids
-contain more energy, but are not the immediate source
-CHO
-Fats: 1 glycerol + 3 fatty acids
-Phospholipids:
Phosphate + glycerol + 2 fatty acids
Saturated fatty acids
ALL single bonds
Unsaturated Fatty Acids
At least 1 double bond
Phospholipids structure
Hydrophilic head (attracted to water) on outside, Hydrophobic tail (repelled by water) facing the inside
Are all lipids polar or nonpolar?
Nonpolar
Water: bonds between oxygen and hydrogen IN the water molecule
Polar covalent bonds
Water: bonds between oxygen and hydrogen BETWEEN water molecules
Hydrogen bonds
Cohesion
water molecules attracted to other WATER molecules
Adhesion
Water molecules attracted to other POLAR substances
Why is water is a universal solvent
Negatively charged oxygen binds with positively charged ions
Positively charged hydrogens binds to negatively charged ions
Oxygen and nitrogen electronegativity
High
carbon and hydrogren electronegativity
Low
Acids
Increase concentration of H+
