Study Notes
Biomolecules
- Carbohydrates: except Chitin, primary source of energy, composed of monosaccharides, example: starch
- Proteins: built and repair body tissues, composed of amino acids, example: hemoglobin
- Lipids: insulation and energy storage, composed of fatty acids and glycerol, example: cholesterol
- Nucleic acid: transfer of genetic information, composed of nucleotides, example: DNA
Chemical Kinetics
- Study of the rate of chemical reactions
- Reaction rate: the speed at which a chemical reaction takes place
- Reaction mechanism: a sequence of reaction steps that show how reactants are converted to products
- Factors affecting the rate of reactions
Polarity of Molecules
- Identifying polar or nonpolar molecules based on electronegativity difference
- Nonpolar molecules: electronegativity difference ≤ 0.5
- Polar molecules: electronegativity difference > 0.5
- Covalent bond: formed through sharing of electrons, exists between non-metals
Biological Macromolecules
- Proteins: monomer is amino acids
- Carbohydrates: monomer is monosaccharide
- Lipids: monomer is fatty acids and glycerol
Cosmic Origin of Elements
- Big Bang Theory: most accepted theory about the formation of the universe
- Nucleosynthesis: process of creating new atomic nuclei from pre-existing nuclei
- Big Bang Nucleosynthesis: responsible for the formation of light elements such as Hydrogen and Helium
- Nuclear fusion: process of forming heavier elements, example: Carbon is formed when three Helium atoms are fused
