Study Notes
Amino Acids Overview
- Amino acids are organic compounds that serve as the building blocks of proteins.
- They possess a central carbon atom attached to an amino group, a carboxyl group, a hydrogen atom, and a variable R group.
Nonpolar Amino Acids
- Glycine: Simplest amino acid; facilitates flexibility in protein structure.
- Alanine: Contains a methyl group; commonly involved in energy production and metabolism.
- Proline: Unique for its cyclic structure; influences protein folding due to its rigid structure.
- Valine: An essential amino acid; plays a role in muscle metabolism and tissue repair.
- Leucine: Promotes protein synthesis; essential for muscle growth and recovery.
- Isoleucine: Essential amino acid important for hemoglobin production and energy regulation.
- Methionine: Contains sulfur; acts as a precursor for other amino acids like cysteine.
Aromatic Amino Acids
- Phenylalanine: Precursor to neurotransmitters; essential for proper brain function.
- Tyrosine: Derived from phenylalanine; important for the synthesis of hormones and neurotransmitters.
- Tryptophan: Precursor to serotonin; plays a key role in mood regulation and sleep patterns.
Polar, Uncharged Amino Acids
- Serine: Involved in enzyme function; important for the active sites of some enzymes.
- Threonine: Essential amino acid; involved in protein synthesis and immune function.
- Cysteine: Contains a sulfhydryl group; important for disulfide bonds in proteins, contributing to structure.
- Asparagine: Plays a role in the synthesis of glycoproteins; can serve as a nitrogen donor.
- Glutamine: Most abundant amino acid in the bloodstream; crucial for nitrogen transport and metabolism.
Positively Charged Amino Acids
- Lysine: Essential for protein synthesis; important for collagen formation and hormone production.
- Arginine: Precursor to nitric oxide; plays roles in immune function and blood flow regulation.
- Histidine: Essential for the production of histamine; important in immune response regulation.
Negatively Charged Amino Acids
- Aspartate: Involved in the urea cycle; acts as a neurotransmitter in the brain.
- Glutamate: Major neurotransmitter involved in cognitive functions; plays a role in synaptic plasticity.
