Amino Acids Characs Flashcards
4 types of amino acids
- Nonpolar
- Polar-Neutral
- Acidic
- Basic
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Alanine
Nonpolar
because of aliphatic hydrocarbon group
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Glycine
Nonpolar
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic

Proline
Nonpolar
because of aliphatic cyclic structure
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Phenylalanine
Nonpolar
bcoz of aromatic hydrocarbon group
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Tryptophan
Nonpolar
bcoz of side chain that contains and indole ring which is aromatic
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Methionine
Nonpolar
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Serine
Polar-Neutral
because the polar group is a hydroxyl bonded to aliphatic hydrocarbon groups
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Threonine
Polar-Neutral
bcoz the polar group is a hydroxyl bonded to aliphatic hydrocarbon groups
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Tyrosine
Polar-Neutral
bcoz the hydroxyl group (phenol) is bonded to an aromatic hydrocarbon group
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Cysteine
Polar-Neutral
bcoz the polar side chain contains a thiol group
Identify if amino acid is nonpolar, polar-neutral, acidic, or basic
Glutamine
Polar-Neutral
bcoz it contains an amide group in its side chain
