Comments on the problem from a study on it:

"Chirality is found in almost all molecules occurring in nature. "Molecules are spatial arrangements of interconnected atoms. Many molecules, however, have not only one form, but at least two," explains Professor Carsten Tschierske, a chemist at MLU. When these forms are mirror images of each other it is called chirality.

"Both mirror-image forms are produced in equal numbers during normal chemical reactions in the laboratory. "However, things occur differently in nature: carbohydrates, amino acids and nucleic acids only have one dominant form," explains Tschierske. And with good reason: for example, nucleic acids carry information about our DNA. Even the slightest changes to our genetic material can lead to serious diseases. "If each nucleic acid had two forms, the structure of our DNA would be chaotic because there would be too many possible variations. Life as we know it would be impossible," states Tschierske.

Comment: The bold indicates the probable reason why life's biology has strict chirality, and had to be designed that way.
