Lecture 3 Flashcards
C can bond to 4 other atoms. What word describes this?
Tetravalence.
What does R represent?
An arbitrary alkyl group.
What type of functional group creates a disulphide bridge with another of the same group?
Sulphydryl.
Which amino acid commonly contains a sulphydryl group?
Cysteine.
What acids are phosphates derived from?
Phosphoric acid (H3PO4).
How can phosphate esters be created?
1, 2, or 3 OH groups can be replaced by OR groups.
What are isomers?
2 organic molecules with the same number of atoms of the same elements but different structures.
3 types of isomerism?
Structural, geometric, enantiomers.
How are structural isomers different?
Differ in covalent partners.
How are geometric isomers different?
Differ in arrangement around a double bond.
What are enantiomers?
Molecules differing only in spatial arrangement of groups around a central chiral carbon atom.
Can enantiomers be superimposed on one another?
No.
Do enantiomers differ in physical or chemical properties?
No.
Do enantiomers differ in the way they interact with other optically active compounds?
Yes.
