The 5 areas of study in Chemistry
Biochemistry, Organic Chemistry, Inorganic Chemistry, Analytical Chemistry, and Physical Chemistry
The 3 major intermolecular forces observed in ochem
Hydrogen Bonds, London dispersion force (or van der Waals Forces), and dipole-dipole interactions
This is used in biochemistry to catalyze a chemical reaction
Enzymes
This analysis is the measurement of the quantities of particular chemical constituents present in a substance
Quantitative analysis
The substance that controls the quantity of product that can form in a chemical reaction
Limiting reactant
An outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond
Valence electron
The most stable conformation for Newman Projections
Staggered conformation
A molecule that interacts with an enzyme and results in decreased activity
Inhibitor
The term for the solvent entering the column in column chromatography
Eluent
Useful when determining the organic/aqueous layer during extraction
Water test, density of reagents or volume of reagents
A large collection of particles moving at random through a volume that is primarily empty space
Gas
Lewis structures that are interchangeable by moving electrons
Resonance structures
These are the 3 types of proteins
Fibrous, globular, and membrane
The process of separating compounds in a mixture by injecting a gaseous or liquid sample into a mobile phase and passing the gas through a stationary phase
Gas chromatography
Functions on the same principle as all chromatography with the goal being to obtain well-defined, well-separated spots.
Thin layer chromatography, TLC
The tendency of an atom to attract shared electrons to itself
Electronegativity
Hydrogens that point either straight up or straight down in chair conformations
Axial hydrogens
A repulsive force between solute and solvent molecules, responsible for minimizing order amongst water.
The hydrophobic effect
A ‘normal’ distribution that follows the standard bell shaped curve
Gaussian distribution
The weight of the material is the difference between the two weights of the vial before and after you transfer the material from the vial
Weighing by difference
Diagrams that show the bonding between atoms of a molecule, as well as lone pairs that may exist in the molecule
Lewis structures/ lewis dot structures
A mixture that contains equal amounts of 2 enantiomers
Racemic mixture
This method of protein purification is based on the interaction between proteins and a particular molecule bound to resin
Affinity chromatography
The bonds and functional groups that give rise to the absorption of UV/Vis radiation
Chromophores
A method to prevent bumping of solvents when using the rotary evaporator (rotovap)
Using a flask that accommodates approximately twice the starting volume or lowering the flask into a water bath
