Study Notes
Amino Acids and Their Functions
- Proteins, made up of amino acids, perform various functions in the body.
Amino Acid Tyrosine
- Tyrosine is an amino acid with an important function as a precursor to hormones and neurotransmitters.
- Tyrosine is converted into neurotransmitters, such as dopamine, norepinephrine, and epinephrine.
Amino Acid Derivatives
- The uncharged derivative of an acidic amino acid is glutamine.
Phenylalanine and Hormones
- Phenylalanine is a precursor to the hormone thyroxine (thyroid hormone).
Tyrosine and Neurotransmitters
- Tyrosine is a precursor to neurotransmitters, such as dopamine, norepinephrine, and epinephrine.
