Describe the structure of Glycine
|
Glycine is the simplest amino acid. It only has an H for an R-Group
|
|
What is unique about Glycine?
|
It's alpha carbon is achiral
|
|
Describe the structure of Alanine
|
It is the second simplest amino acid because its R-Group sis just -CH3
|
|
What are the amino acids with aliphatic side chains?
|
Valine, Leucine, Isoleucine, and Methionine
|
|
Describe the structure of Valine
|
It's R-Group is CH(CH3)2
|
|
Describe the structure of Leucine
|
It's R-Group is -CH2CH(CH3)2
|
|
Describe the structure of Isoleucine
|
It's R-Group is -CH(CH3)CH2CH3
|
|
How many chiral centers does Isoleucine have?
|
2 chiral centers, one in the R-Group and the other in the backbone
|
|
Describe the structure of Methionine
|
It's R-group is CH2CH2SCH3
|
|
Describe the structure of Proline
|
It is a very rare cyclic molecule in which the R-Group binds to the alpha carbon twice with different atoms. Its structure is:
-CHCH2CH2CH2NH2+----back to alpha carbon. It is a 5 member ring. |
|
Describe the structure of Phenylalanine
|
Its R-Group is -CH2-Phenyl (benzene ring)
|
|
Describe the structure of Tyrosine
|
Its R-Group is -CH2-Phenol (benzene with OH group instead of H across from the C that attaches it to the R group)
|
|
Describe the structure of Tryptophan
|
Its R-group is -CH2-5 member ring with NH at the pentagon tip which also shares two carbons with a benzene ring
|
|
