Study Notes
Amino Acid Classification
- Amino acids can be categorized into three groups based on their chemical properties: Electrically Charged, Polar, and Nonpolar.
Electrically Charged Amino Acids
- Further divided into Acidic and Basic subcategories.
Acidic Amino Acids
- Aspartic Acid (Asp)
- Glutamic Acid (Glu)
Basic Amino Acids
- Lysine (Lys)
- Arginine (Arg)
- Histidine (His)
Polar Amino Acids
- Display both hydrophilic and hydrophobic properties.
- Serine (Ser)
- Threonine (Thr)
- Cysteine (Cys)
- Tyrosine (Tyr)
- Asparagine (Asn)
- Glutamine (Gln)
Nonpolar Amino Acids
- Also known as hydrophobic amino acids.
- Glycine (Gly)
- Alanine (Ala)
- Valine (Val)
- Leucine (Leu)
- Isoleucine (Ile)
- Methionine (Met)
- Tryptophan (Trp)
- Phenylalanine (Phe)
- Proline (Pro)
