On Divine Land, the roots of every creature's bloodline, their amino acids, and the Path of Living Beings Source were all left-handed, while all sugars produced by living organisms were right-handed.
The Path of Living Beings Source formed every tissue in the human body and built the framework of cells. Thus, every macromolecule of living matter within the human body could be said to possess left-handed properties.
And such flesh could happen to absorb right-handed sugars and use them as a source of energy.
This could actually be compared, somewhat inappropriately, to screws and nuts.
But there was one very strange phenomenon.
The glucose produced by plant photosynthesis was entirely right-handed, while the amino acids synthesized by plants were entirely left-handed. Yet under artificial preparation, left-handed and right-handed macromolecules were usually close to half and half—because carbon in nature was half left-handed and half right-handed, and many changes in material properties [chemical reactions] did not involve inversion.
For substances originating from natural living beings, the chirality of every substance was fixed. Amino acids were certainly left-handed, and sugars were certainly right-handed.
This mysterious phenomenon remained a riddle even now.
When she heard that the dragon race also understood this subject, Ai Qinglan immediately grew excited.
"Ah, you should know a great deal about chirality, right? Why can living beings produce this kind of chirality?"
Yue Luo Liuli averted her gaze. "Ahem, ahem. That's classified too."
Chen Feng shook his head. "I can tell..."
"Perhaps it was a problem that existed from the very beginning of evolution." Ai Qinglan shook her head. "Absorbing both kinds of sugar is far less efficient than absorbing only one, so living beings with isomers of both chiralities were eliminated?"
"Then following that line of thought, Divine Land should be divided between left-handed and right-handed races,"
