A. Is part of the Carbonyl groupd when the molecule is in the middle of the chain.
B. ex) acetone.
Describe the Carboxyl Group.
A. Known as Carboxylic Acids or Organic Acids.
B. Part of the Amino Acid structure; therefore, it is important in the structure of proteins.
What type of backbone does DNA have?
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 Glycine?
The simplest Amino Acid.
What is the meaning of hydropilic?
"Water-loving," or polar.
What is the meaning of Hydrophobic?
"Water-fearing," or non-polar.
Describe the Hydroxyl Group.

A. Also known as the Organic Phosphates.
B. Often functions in energy transfer reactions between molecules. (ATP)
C. Leads to DNA having a negative charge.
Describe the Sulfhydral Group.
A. Also known as the Thiols.
C. Important in protein structure because -SH likes to form bonds together.
Does an acid accept or donate hydrogen?
What is a Bioassay?
A test on a living organism.
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."
