What is dehydration synthesis?
The general process that links monomers together into a polymer

100

What is an alpha helix?
"right-handed" spiral structure in protein

100

What is glycogen?
A highly branched polymer of glucose used for storage of sugar in animals.

100

What is cholesterol?
A lipid not based on fatty acids and the basis of many hormones.

100

What is unsaturated?
A carbon-carbon bond that could have more hydrogens added

200

What is a peptide bond (or "amide")?
When two amino acids are joined, the resulting bond is known as this

200

What is quaternary structure?
when two or more polypeptides come together to form a protein.

200

What is Cellulose?
A polymer of glucose used to provide structure strength in plants.

200

What is a fatty acid?
A long chain hydrocarbon with an acid at the end

200

What are saturated fatty acids? (could accept trans double bonds)
Fats that are solid at room temperature tend to have these

300

What are sugars?
A "glycosidic bond" results when two of these are joined.

300

What is primary structure?
The sequence of amino acid residues that comprise a polypeptide.

300

What is starch? (amylose). 300 more points: what is the slightly branched form?
The non-branched polymer plants use to store glucose

300

What is a fat?
Three fatty acids attached to glycerol, or "triacylglyceride."

300

What is the peptide backbone?
"amine-"alpha" carbon-carbonyl carbon-amine-alpha carbon-carbonyl carbon-amine-alpha carbon-carbonyl carbon.....

400

What is an ester? (fatty ester)
The link between a fatty acid and glycerol

400

What are beta sheets.
Sometimes described as "pleated," these are made of strands of polypeptide that link together in parallel or anti-parallel formation by hydrogen bonds

400

What is beta glycosidase.
Of the two enzymes: alpha glucosidase and beta glucosidase, the one that can digest cellulose (you might be able to figure it out if you think about it).

400

What is a phospholipid?
The major component of a lipid bilayer

400

What is a chiral carbon?
An atom of carbon that has four unique things connected to it, and therefore can exist in two mirror forms

500

What are hydrogen bonds? (accept hydrophobic interactions or dispersion forces)
non-covalent interaction that hold together many structures.

500

What is tertiary structure?
Mediated by the "R" side chains, it gives a single polypeptide its 3-D fold.

500

What is 0?
The difference in mass between the linear form of glucose and the cyclic form.

500

What is a trans bond?
A form of double bond normally not found in fatty acids in nature

500

What is an amphipathic helix?
a helix with a hydrophobic face and a hydrophilic face
