What is the size of amino acids in nm or Angstroms?

Click For Summary
SUMMARY

The physical size of amino acids, specifically glycine and alanine, is approximately 0.42 nm, making glycine the smallest amino acid. This measurement is supported by data from the BioNumbers database and referenced in the book 'Introduction to Nanotechnology' by Poole C and F J Owens. The size estimation is based on bond length and bond angle calculations, providing a precise understanding of amino acid dimensions in nanometers.

PREREQUISITES
  • Understanding of molecular biology concepts
  • Familiarity with nanotechnology principles
  • Knowledge of bond lengths and angles in molecular structures
  • Access to scientific databases like BioNumbers
NEXT STEPS
  • Research the molecular structure of alanine and its size in nanometers
  • Explore the implications of amino acid size on protein folding
  • Learn about the significance of bond lengths in molecular chemistry
  • Investigate other amino acids and their dimensions using the BioNumbers database
USEFUL FOR

Students and researchers in molecular biology, biochemistry, and nanotechnology, as well as anyone interested in the physical properties of amino acids and their role in biological systems.

Just wondering what the physical size of amino acids such as glycine and alanine are in nm or Angstroms.

Thanks.

Hmm. I found ~0.42nm as a size estimate of a glycine molecule, the smallest amino acid.
