Amino Acids

Professor Dave Explains2 minutes read

Biomolecules in the body, such as proteins, are composed of amino acids with unique R-groups, categorized based on their properties. The pH of the environment plays a crucial role in determining the form of amino acids for proper protein synthesis and function.

Insights

  • Proteins, essential for various biological functions, are constructed from amino acids that can exist in different forms based on the pH of their environment, highlighting the critical role of pH regulation in maintaining protein structure and function.
  • The distinction between essential and non-essential amino acids underscores the importance of a balanced diet in providing the necessary building blocks for the body, emphasizing the significance of understanding the composition and function of biomolecules for overall health and well-being.

"Essential amino acids and protein polymerization"

  • Biomolecules in the body include proteins, carbohydrates, lipids, and nucleic acids, which are polymers made up of monomers. Amino acids are the first type of monomer, each consisting of an amino group, a carboxyl group, and a unique side chain known as the R-group.
  • There are about 20 amino acids with varying R-groups, categorized as hydrophobic, aromatic, basic, acidic, or nucleophilic. Essential amino acids must be obtained from the diet, while non-essential amino acids can be synthesized within the body.
  • Amino acids exist in different forms based on pH, with equilibria between cationic, zwitterionic, and anionic forms. The pH of the environment determines the predominant form, with precise regulation to maintain a neutral pH and allow for polymerization to form proteins.
