Biological significance of amino acids
Accepted Answer
Amino acids are vital to life and have a wide range of biological significance:
1. Protein Synthesis: Amino acids are the building blocks of proteins, which are essential for a variety of biological functions, including structural support, enzyme catalysis, hormone regulation, and immune response.
2. Neurotransmitters: Some amino acids, such as dopamine, serotonin, and GABA, act as neurotransmitters, transmitting signals between nerve cells in the brain and nervous system.
3. Metabolism: Amino acids are involved in various metabolic pathways, including energy production, gluconeogenesis, and urea synthesis.
4. Gene Expression: Certain amino acids, such as methionine, are involved in regulating gene expression and protein synthesis.
5. Antioxidants: Some amino acids, particularly cysteine and methionine, have antioxidant properties, protecting cells from damage caused by free radicals.
