Many common biological macromolecules such as proteins, ribose, and cellulose are inherently chiral. Chiral molecules have two

It is a mysterious phenomenon that almost all chiral molecules in living organisms are found in one form, such as right-handed sugars, left-handed amino acids, and right-handed DNA coils.
