Dextrorotatory World
Because the biosphere is dominated by Dextrorotatory Enzyme, the most basic biomolecules that make up the biosphere are also dextrorotatory.
Just like amino acids, it is well known that Levorotatory Amino Acid and Dextrorotatory Amino Acid have different biological activities in living organisms. Earth's organisms typically only contain Levorotatory Amino Acid, while Dextrorotatory Amino Acid are rarely found. This is because enzymes and other enzymes in Earth's organisms can only recognize and catalyze Levorotatory Amino Acid, but not Dextrorotatory Amino Acid.
In other words, if a person ingests too much Dextrorotatory Amino Acid, it will not be absorbed by the body, thus causing health problems.
It is said that Dextrorotatory Amino Acid are rarely found in terrestrial organisms, but that does not mean they are not present. For example, Dextrorotatory Amino Acid are present in the human body.
The left-handed and right-handed amino acids also have different physiological functions. Levorotatory Amino Acid are the basic building blocks of proteins and have many physiological functions such as promoting growth, maintaining tissue structure and metabolism.
Dextrorotatory Amino Acid play different roles in the body's metabolism and are usually used as drugs or nutritional supplements.
In other words, these two pieces of bad news have different impacts on different aspects of human society.
In terms of science, it is undoubtedly a positive impact.
The reason is that the Earth's biosphere is predominantly left-handed, and Dextrorotatory Amino Acid have significantly different chemical properties from Levorotatory Amino Acid. Theoretically, Dextrorotatory Amino Acid can also form the biosphere, but they will never be like the Earth's biosphere.
Humans had previously imagined what Levorotatory Biosphere would look like, but had never seen one. Now that they have, the biosphere of this planet, dominated by Dextrorotatory Enzyme, is so vibrant and so amazing.
Of course, the most basic molecules that make up this planet are not Dextrorotatory Amino Acid, but another kind of right-handed macromolecular structure, which scientists have confirmed.
However, its research significance remains very important, even more so than that of the Levorotatory Biosphere.
In other aspects, however, the impact is less favorable.
People used to think that once they encountered such a Life Planet, and their research yielded results that allowed humans to adapt to this biosphere, their dining tables would be laden with meat.
With so many plants on the planet, there must be suitable ones that can be used as seasonings or something. Those mouths that have been so dry they've practically bland can finally be satisfied.
Unexpectedly, it turned out to be Levorotatory DNA biosphere and Dextrorotatory Enzyme world.
The Levorotatory Biosphere here refers to the biosphere composed of organisms with left-handed DNA structures. Such a biosphere is called Dextrorotatory World because it uses right-handed Dextrorotatory Enzyme. Since the DNA of all life on Earth is right-handed, it is called a right-handed biosphere. The right-handed biosphere almost exclusively uses left-handed enzymes, hence the name left-handed world.
Left rotation does not mean turning left, and right rotation does not mean turning right; rather, it refers to the left and right rotation of the hand.
And so, people's culinary dreams were shattered.
You can't just eat right-handed foods, it can kill you, unless humans have the technology to modify themselves from the DNA up to the point where they can utilize right-handed foods.
Just think about the infamous 'Contergan incident' to understand how serious the consequences of consuming dextrorotatory substances can be.
In 1957, the German pharmaceutical company Glennsur developed a drug Thalidomide, also known as Phthalimidopiperidinone. Scientists at the time discovered that it could control stress during pregnancy and significantly suppress morning sickness. Once a pregnant woman took the drug, nausea and vomiting would immediately disappear, and it also had a sedative effect, making it a veritable miracle drug. Therefore, this drug was also known as 'Contergan'.
However, within just three years, numerous deformed infants with abnormal hands and feet appeared throughout West Germany. Dr. Lenz then investigated these deformed fetuses and published an article in 1961 stating that 'the cause of the deformity is Contergan '.
Studies have shown that mothers who take Contergan during the first one or two months of pregnancy are more likely to give birth to deformed babies. These deformed babies have shorter limbs than normal, or some have no limbs at all, resembling seals.
Its mechanism is to act on genes; this drug blocks the transmission of instructions in the Gene Code of life, such as the length of hands and feet, the number of fingers, etc.
By 1963, there were 12,000 cases of birth defects in various countries around the world, such as West Germany, the United States, the Netherlands, and Japan, due to the use of this drug.
Scientists have discovered that the root cause of this disaster was actually the chiral carbon structure of Thalidomide. The dextrorotatory form can alleviate morning sickness, while the levorotatory form not only lacks medicinal activity but can also cause birth defects in the fetus.
The chemical formulas of these substances are exactly the same, except that they have both levorotatory and dextrorotatory structures. Because of the ignorance of these optical isomers at the time, drugs contained both levorotatory and dextrorotatory components, leading to this tragedy.
Therefore, it's important to distinguish between left-handed and right-handed spirals, as humans cannot easily consume anything in such a vast biosphere.
Of course, this must contain some answer to the universe and some truth about life.
If humanity can thoroughly study this Levorotatory Biosphere, which is mainly composed of Dextrorotatory Enzyme, it will undoubtedly make significant progress in the field of Life Science.
Perhaps the Enhancement Elixir that humanity has been searching for lies hidden in the truth of this left-right rotation.
Therefore, this is a discovery that pleases scientists but displeases the food-loving public.
"Is there any explanation for the formation of the Levorotatory Biosphere?" Yue Yuan's face beamed with joy. He was originally a foodie, but he was more concerned about the scientific progress of mankind.
After asking the question, he turned to look at Yi Kai, who was gulping down water, and thought to himself: With such a magical biosphere, could the Enhancement Elixir allow us to overtake it and achieve our goal before the Acceleration Buffer Fluid? Yi Kai tightened the cap on his water bottle, then stuffed it into his pocket before answering. "From a biological evolutionary perspective, I believe that the basic structure of life that initially arose on this planet was roughly equal in left-handed and right-handed spirals. Later, as time went on, perhaps some events occurred that altered the planet's environment..."
Events such as mass extinctions in Earth's evolutionary history caused the planet's environment to suddenly become unsuitable for organisms with Dextrorotatory DNA, leading to the dominance of organisms with Levorotatory DNA.
Once this ecological balance is broken, it becomes uncontrollable. The more numerous the species, the greater the probability of poisoning the fewer species, thus reducing the number of fewer species. Over time, there will be nothing left on the planet for right- or Levorotatory DNA organisms to eat, and only Levorotatory DNA organisms will remain.
"Just as our Earth only has Dextrorotatory DNA structures, the presence of left-handed and right-handed DNA should be considered an evolutionary probability. This is because although Earth is dominated by Levorotatory Amino Acid, it also contains a small number of right-handed Dextrorotatory Amino Acid, such as those found in the human body."
I think this is probably a small group of coexisting relationships formed over billions of years of evolution, where Dextrorotatory Amino Acid competed with each other. This is also why we don't die immediately after consuming Dextrorotatory Amino Acid, and sometimes they even have therapeutic effects—because those Dextrorotatory Amino Acid that could poison us died out billions of years ago.
Yes, just like how Cyanobacteria and red algae, fungi and archaea formed a symbiotic relationship during the long process of evolution. Hearing Yi Kai say this, Yue Yuan recalled the evolutionary story of ancient life on Earth.
