Many biologically active molecules are chiral, including the naturally occurring amino acids (the building blocks of proteins) and sugars. The origin of this homochirality in biology is the subject of much debate. Most scientists believe that Earth life's "choice" of chirality was purely random, and that if carbon-based life forms exist elsewhere in the universe, their chemistry could theoretically have opposite chirality.
