The chemical nature of the side chain determines the nature of the amino acid (that is, whether it is acidic, basic, polar, or nonpolar). For example, the amino acid glycine has a hydrogen atom as the R group. Amino acids such as valine, methionine, and alanine are nonpolar or hydropho...
There is little wonder in the fact that the investigation of amino acids is of fundamental interest to scientists from so many diversified fields. If amino acids were only basic constituents of enzymes as well as structural and other proteins, this property alone would elevate them to real scient...

Chirality—the fundamental phenomenon of handedness—ranges across nature from the atomic arrangement of amino acids to the long, macroscopically helical tooth of the narwhalMonodon monoceros1. Chirality is ubiquitous in biology, including in calcium carbonate biomineralization, and it is found in many ...
Amino acidsare a particular case in point as they can exist in a variety of chemical forms depending on their environment, ranging from zwitterionic, NH3+RCOO−, (the usual solid state form), anionic, NH2RCOO−, cationic, NH3+RCOOH, to neutral, NH2RCOOH, (the usual gaseous form). Th...
