Term
Term for the functional group where phosphate is bound to four oxygens (1 double bond). A critical structure in DNA.
Definition
Phosphate
Term
Compounds that have the functional group C=O on the end.
Definition
Aldehydes
Term
Term for the functional group C=O.
Definition
Carbonyl
Term
The most important biologically active molecule.
Definition
Carbon
Term
Valence of hydrogen as well as the number of bonds it can form.
Definition
One
Term
The number of bonds carbon forms (the same as its valence).
Definition
Four
Term
Mirror image isomers formed from four different molecules attached to a single carbon.
Definition
Enantiomers
Term
Compounds that have the functional group O-H.
Definition
Alcohols
Term
Compounds that have the functional group N-H2.
Definition
Amines
Term
Form of chemistry that specializes in the study of carbon compounds.
Definition
Organic
Term
Term for the functional group HO-C=O.
Definition
Carboxyl
Term
Term for the functional group S-H.
Definition
Sulfhydryl
Term
Biological molecules that are stabillized by the functional group S-H.
Definition
Proteins
Term
Compounds that have the functional group HO-C=OH.
Definition
Carboxylic Acid
Term
Compounds that have the functional group C=O not on the end.
Definition
Ketones
Term
Term for the functional group O-H.
Definition
Hydroxyl
Term
Term for the functional group N-H2.
Definition
Amino
Term
Type of isomer that shares the same covalent partnership, but differs in spacial arrangement due to carbon's multiple bonds.
Definition
Geometric
Term
Compounds with the same molecular formula but with different physical structures.
Definition
Isomers
Term
Compounds that have the functional group S-H.
Definition
Thiols
Term
What are the basic Hydrocarbons?
Definition

Methane

Ethane

Propane

Butane

Term

Definition
CH4 - Methane
Term

Definition
C2H6 - Ethane
Term

Definition
C3H8 - Propane
Term
[image]
Definition
C4H10 - Butane
Term
How does the name of hydrocarbons differ with double bonds?
Definition
Ethene
Propene
Butene
Term
How do you number them based on their double bond location?
Definition
I.e. If the double bond is between the 1st and 2nd Carbon, it is 1 Butene.

If the double bond is between the 2nd and 3rd Carbon, it is 2 Butene.

However, if the double bond is between the 3rd and 4th Carbon, it would simply be 1 Butene because you can rotate the isomer and it would be the same as 1 Butene.
Term
How do Carbon skeletons vary in structure?
Definition
-Length
-Shape
-Number/location of double bonds
-Other elements covalently bonded to available sites.
Term
What is an isomer?
Definition
Compounds with the same molecular formula but with different physical structures.
Term
What are the three different kinds of isomers?
Definition
Structural
Geometric
Enantiomers
Term
How are the different kinds of isomers different?
Definition
Structural: different arrangement

Geometric: differ due to double bond

Enantiomers: mirror images
Term
What is a structural isomer?
Definition
Isomers that have the same molecular formula but differ in the covalent arrangement of atoms
Term
[image]
Definition
An example of a structural isomer.
Term
What is a geometric isomer?
Definition
Compounds with the same covalent partnerships that differ in their spatial arrangement around a C=C.

Happens because double bonds prevent C from rotating around the bond axis.
Term
[image]
Definition
An example of a geometric isomer.
Term
What is cis?
Definition
When two atoms are locked on the same side of a double bond.

(cis: from Latin meaning "on this side")
Term
What is trans?
Definition
When two atoms are locked on the opposite sides of a double bond.

(trans: from Latin meaning "across" - as in transatlantic)
Term
What is an optical isomer (enantiomer)?
Definition
Isomers that are mirror images of each other.
Term
[image]
Definition
An example of an enantiomer.
Term
How is enantiomers defined?
Definition
Because 4 different atoms attached to the same Carbon, there is no possible way to rotate these molecules so tthat they are identical. -Same Plane-

(Enantio: from Greek meaning "opposite")
(Mer: from Greek meaning "part")
Term
What does achiral mean?
Definition
Not handed
Term
What does chiral mean?
Definition
Handed
Term
What is the L-form of enantiomers?
Definition
Biologically active
Term
What is the R-form of enantiomers?
Definition
Do nothing
Term
What is an exception to normal enantiomer forms?
Definition
Prozac's D-form is probably the only effective form while the L-form causes sexual side affects.
Term
Do the enantiomer name designations differ in medicine versus science?
Definition
Yes.

Biology: L-form (left) and D-form (right)

Medicine: L-form (sinister) and R-form (rectus)
Term
