Study Notes
Amino Acid Properties
- Amino acids can be classified into three main categories: nonpolar, polar, and electrically charged.
Nonpolar Amino Acids
- Nonpolar amino acids are hydrophobic (water-repelling) and tend to be located in the interior of proteins.
- Examples of nonpolar amino acids include:
- Glycine (Gly)
- Alanine (Ala)
- Valine (Val)
- Leucine (Leu)
- Isoleucine (Ile)
- Methionine (Met)
- Tryptophan (Trp)
- Phenylalanine (Phe)
- Proline (Pro)
Polar Amino Acids
- Polar amino acids are hydrophilic (water-attracting) and tend to be located on the surface of proteins.
- Examples of polar amino acids include:
- Serine (Ser)
- Threonine (Thr)
- Cysteine (Cys)
- Tyrosine (Tyr)
- Asparagine (Asn)
- Glutamine (Gln)
Electrically Charged Amino Acids
Acidic Amino Acids
- Acidic amino acids have a negative charge.
- Examples of acidic amino acids include:
- Aspartic Acid (Asp)
- Glutamic Acid (Glu)
Basic Amino Acids
- Basic amino acids have a positive charge.
- Examples of basic amino acids include:
- Lysine (Lys)
- Arginine (Arg)
- Histidine (His)
