|
|
What is a Functional Group?
|
A. Ensembles of atoms often attached to Carbon chains (hydrocarbons) that give the entire molecule specific chemical and physical properties.
B. Each of the groups behave consistently from one organic molecule to the next. |
|

|
What is chromotography?
|
A. Group of lab methods, based on selective absorption, by which components of complex mixtures can be identified and/or purified.
B. First described in 1906. C. Named it because plant pigments studeied resulted in colored bands. |
|
|
What is column chromotography?
|
A. Molecules are seperated by passing them through a column consisting of a mobile phase 9liquid, gas) and a stationary phase (solid, liquid).
B. Seperation based on each molecules degreee of attraction, or affinity, for mobile or stationary phase. |
|
|
What is an eluent? (Eluding)
|
What comes out; what's coming out of the column.
|
|
|
What is the formula for finding weight, or mass, of a molecule?
|
Number of atoms X mass number
|
|
|
What is a fraction in regards to gel filtration?
|
How you collect the eluent. (The amount collected)
|
|
|
What is a basic description of Gel Filtration?
|
A. Seperates molecules by size only.
B. Larger molecules elute from the column first because they have a shorter path through the beads. C. Used to purify proteins or other molecules of interest. D. Used to estimate size of unknown proteins. E. Also known as "Molecular Exclusion." |
