What is a triacylglycerol?
- Three fatty acids linked to one glycerol molecule.
-
MACROMOLECULE!!!!!!
Giant molecule formed by the joining of smaller molecules usually by a condensation reaction. Polysaccharides, proteins, and nucleic acids are macromolecules.
-
Nucleic Acid
A polymer (polynucleotide) consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA.
-
Carbohydrate
A sugar. Plain and simple.
-
Glycogen
An extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch.
-
Monosaccharide
Known as a simple sugar, generally the formula is some multiple of CH2O

-
Which two polysaccharides are used for energy storage?
Glycogen and Starch
-
Which two polysaccharides are used for structure?
Cellulose and Chitin
-
Which polysaccharide used for energy storage is released s l o w l y?
Starch, because it is in linear form and it isn't branched. Remember, Starch = Slow.
-
Which polysaccharide used for energy storage is released quickly?
Glycogen, because it is branched, making it easier to break off from other molecules in the chain.
-
What type of bond links fatty acid chains to glycerol molecule?
Ester Linkage. Think, Ester sounds like a fat chick name and Ester Linkages make up fats.
-
Name the three parts of a phospholipid.
-
Cholesterol and sex hormones are an example of what? What is the definition?
Steroid: A type of lipid characterized by a carbon skeleton consisting of four rings with various functional groups attached.
-
What four components make up an amino acid?
- Carboxyl Group: Gives acidic properties and name
- Amino Group: Gives NH2 and amino name
- Central Carbon: AKA asymmetrical carbon
- "R" Group: AKA functional group
-
A peptide bond is a covalent bond between the [blank] group of one amino acid to the [blank] group of another.
Amine, Carboxyl C-N
-
Which protein structures are altered when a protein is denatured?
A) Primary
B) Secondary
C) Tertiary
D) Quaternary
E) Primary and Secondary
F) Secondary and Tertiary
G) All levels are altered
F) Secondary and Tertiary
