1Amino Acid GroupsPolar, Nonpolar, Charged (acidic and basic)
2Characteristics of non-polar AA's, # non-polar AA's9 non-polar AA's
Usually has a C or H, cannot give off protons, no net charge
Do not form H bonds
Have hydrophobic interactions
3Glycine- abbreviation, group, and special characteristicsGly, non-polar
Smallest and simplest AA
R group has a single H
Alpha carbon is chiral
4Alanine- abbrev., group, characteristicsAla, non-polar
R group is CH3
5ValineVal, non-polar
Isopropyl R group (3 carbons)
6Leucine-abbrev., group, characteristicLeu, non-polar
Valine + extra C
7Isoleucine- abbrev., group, characteristicIle, non-polar, rearranged leucine
8Phenylalanine- abbrev., group, characteristicPhe, non-polar
Only non-polar amino acid with aromatic group
9Tryptophan- abbrev., group, characteristicTrp., non-polar
2 rings
1 N
10Methionine- group, abbrev., characteristicMet, non-polar
Essential AA - only get it from diet
Has S --> only non-polar because methyl group is shielded
11Proline- abbrev., group, characteristicPro, non-polar
Amino group cyclized with R group
Amino group becomes imino group
12AA's with uncharged polar R groups, # of AA's and characteristics of group6 AA's
0 charge at neutral pH
13Serine- abbrev., group, and characteristicsSer., polar uncharged
Contain polar -OH group and can form H bonds
R-group is important active site for enzymes
14Threonine- abbrev., group, characteristicsThr., polar uncharged
Has polar -OH
Site of attachment for PO4- group
-OH can form H bonds
