The corners of Li Ang's mouth turned up, and he said with a smile, "Why did I wake up in pain all over my body, and I got better immediately after installing the battery,

Why does the rubber-clad figure leave a sweet liquid in the grooves of the wall after opening the stone wall?

Why am I asked to use sugar cane to make battery fluid in room F?

The reason is very simple, the so-called battery is not to provide energy for this suit on my body.

It's about giving me energy.

What the hell..."

He stretched out his finger and pointed to the glass cylinder on his left arm, "It's just ordinary glucose." ”

“...”

Alice didn't speak, just turned her head slightly, "looking" at the battery that Leon was pointing to.

"Glucose, molecular formula C6H12O6, according to the encyclopedia, it is the most widely distributed and important monosaccharide in nature, a polyhydroxyaldehyde, is the energy source of living cells and metabolic intermediates, that is, the main energy supply substance of living organisms.

However, glucose here refers to D glucose,

And this tube on my shoulder is L glucose. ”

Li Ang rubbed the bridge of his nose that was pressed by the mask, and said indifferently: "The position of the last hydroxyl group of D-glucose and L glucose is different.

The chirality is different, and they are mirror images of each other, and they are enantiomers.

The so-called chirality is an essential attribute of nature.

The carbon atom has four chemical bonds that can connect four functional groups,

Due to the variety of functional groups, organic matter also has asymmetry, i.e., chirality.

When a certain carbon atom is the chiral center, there will be two spatial structures,

The atoms of the two configurations are the same, but they are mirror images of each other.

It's like the left and right hands of human beings, which cannot be coincident by rotation,

Hands are usually identified by R-S or D-L.

Molecules of different configurations only change in spatial three-dimensional structure, but they may be very different in physiological and pharmacological activities.

For example, a drug of thalidomide,

Its R type can play a sedative effect and relieve vomiting in pregnant women, so it is used as a drug to inhibit pregnancy reaction.

However, the S type has a strong teratogenic effect.

If R and S are not separated, a large number of malformed fetuses will be produced.

The same goes for this tube of L-glucose.

Normal D-glucose successively produces carbon dioxide and water through the aerobic glycolysis pathway, the aerobic tricarboxylic acid cycle and the biological oxidation process, which releases more energy and is stored in the form of ATP.

However, the enantiomer of D-glucose, L-glucose, cannot be phosphorylated by hexokinase, which means that it cannot be used by normal mammals. ”

Leon stretched out his finger and pointed to his nose, "That is, I'm not a normal mammal. ”

Alice asked softly, "How did you know it was L-glucose..."

"The reason is simple,"

Leon shrugged, "Actually, as a puzzle game, he gave me too many hints.

The envelope in room A smells of lemon,

E room L menthol smells musty,

Aspartyl, which tastes crying,

Ramie has the same lemon fragrance as the envelope in room A."

He picked up a few bottles that were tied to a strip of cloth on his waist and introduced them in turn, "Menthol is a type of cyclic monoterpene, a highly volatile essential oil produced by plants.

Menthol has a cool minty aroma, but its enantiomer D-menthol has a musty smell.

Asparagine is sweet, but its enantiomer R-asparagine is bitter.

There are two chiral subclasses of limonene, one is lemon flavor and the other is orange flavor.

Before I stepped through the stone gate, I always smelled lemon,

And now...."

He opened the jar of ramie, took a deep breath, and smiled at Alice, "It smelled of oranges."

If I'm not mistaken, one of the effects of this road,

It's the whole body that flips into it,

The human mirror is symmetrical, so that all the small protein nucleic acid molecules in the body are chiral inversion together.

Consequences,

That is, those who enter the Yongdao cannot use conventional D-glucose.

Instead, I can only use artificially synthesized L-glucose as a source of energy - that's why I'm limited to only three hours of activity.

At the same time, it is also the reason why the alchemist said that going down the well will bring sequelae, and it is necessary to isolate the effect with special clothing. ”

He raised his arm, pointed to the stone wall behind him with his thumb, and smiled, "Do you remember the code for the door of room E?"

Mobius, Mobius.

Take a long white slip of paper and blacken the reverse side,

Then flip one end over,

When the two ends are connected, they form a Möbius strip.

If you take a circle along Möbius, then the left becomes the right, and the upper becomes the lower,

Just like chiral reversal.

The well is the Möbius belt, which is the Yongdao,

The special garment that the alchemist refers to is the one I am wearing—but this garment may be missing some key parts,

As a result, I didn't shield the chiral inversion effect,

It wasn't until I got out of the stone wall that I got back to normal. ”

Li Ang said in a deep voice: "In room D, the alchemist's own desk calendar says that he will be on the day of March 2,

On behalf of his wife, he went to Amestolis to receive the Order of the Alchemist of Plants from the President.

At the same time, I also want to visit my teacher who has been working on alkylating agents recently.

Alkylating agent is a class of highly chemically reactive compounds, belonging to cytotoxic drugs, which can form carbocations or other compounds with active electrophilic groups in the body.

In turn, it covalently binds to electron-rich groups in biological macromolecules in cells, making them inactive or breaking DNA molecules.

Mainly used for malignant lymphoma and chronic lymphocytic leukemia,

It's just the right thing to say about your sister Ciri's disease.

Considering that the development of medicine and chemistry in this world is not high, there is a high probability that the technology of high-efficiency chiral catalyst has not been pointed out.

Your father should want to use the chiral reversal function of the well, or Yongdao, to make a chiral-specific drug to treat his youngest daughter's disease.

It's a pity that until the final result is achieved,

Tragedy struck,

Perpetuate your father and resort to the most extreme means. ”

Li Ang stretched out his hand and patted the stone wall of the Yongdao, and said calmly: "This Yongdao, I'm afraid it doesn't only have the ability to reverse the hand,

It also has the function of distorting time and creating a loop.

It's like a Möbius ring that never ends,

Or the ferocious Ouroboros devouring its own tail out of greed.

In this way, cause is effect, effect is cause,

There are no boundaries between time and space,

The gap between the past and the future has been blurred.

This mansion, this tragedy, has never been behind the scenes,

Or rather, the only one behind it,

It's the alchemist himself, it's me. ”
