Chapter 115 (2/2)

Meat and vegetables are divided into two areas.

Cheng Nuo and his party first came to the area where vegetables were sold.

”Go and buy some spinach first.” Grandma looked around for a week and said to Cheng Nuo and Jiang Jun.

The two people are totally confused about buying vegetables. They are all people who only know how to eat but not how to make. Not to mention the more difficult shopping. So he nodded to show that he was following grandma's instructions.

Half of the people who sell vegetables don't sell only one vegetable. Most of them put several kinds of vegetables on the shelf for anyone to choose from.

Basically, spinach is sold in every vegetable stall.

Grandmother casually found a few people in the nearest stall.

The owner is a middle-aged woman in her forties. See grandmother come over, the face showed a kind smile, ”Auntie, what do you want to buy? I have many kinds here.”

Grandma laughingly walked to the stall, pointed to the bundles of spinach and said, ”boss, how do you sell spinach?”

”1 yuan, 61 Jin, auntie, would you like some? This is what we just picked last night. It's definitely fresher than that in the supermarket.” With a smile on her face, the woman boasted, ”it's not me. In this vegetable market, my spinach is the freshest. Those spinach that have been picked for more than one day will not be sold here without conscience! ”

The female stall owner patted her chest and promised to do so.

”Really?” Grandmother said with a slightly confused tone.

”Fake!”

The woman stall owner just want to smile, from the grandmother behind a crisp voice interrupted the female stall owner want to speak.”You said It's a fake

Cheng Nuo walked out slowly from her grandmother's back, pointing to the woman stall owner with a face of muddle, and said in a firm and incomparable tone.

”What do you mean, young man?” The woman stall owner looks ugly to say.

”Hum Cheng Nuo snorted softly, and suddenly felt something missing.

Cheng Nuo takes out a glasses case from his pocket and opens it. There are identical eyes with Conan.

Cheng Nuo puts black framed eyes on his face and smiles with Conan's confident smile.

At the same time, a series of data streams flash through Cheng Nuo's eyes.

”Weight 583.25g, number of leaves 34 leaves The water content is 84.25%, and the organic matter content is 56.24g The content of chlorophyll is 0.2 mg / g The growth cycle is 41 days The inhibition rate of pesticide residues was 65.32%, and the potassium content was.... ”

Cheng Nuo already knows all kinds of data about spinach on the female boss's stall.

When Cheng Nuo makes the action of helping his eyes, Jiang Jun, who has been paying attention to Cheng Nuo's every move, beats his heart violently. A word suddenly rises in my heart.

High energy warning ahead, please look at Cheng Nuo quietly!

Cheng Nuo looks at the female boss with the eyes of the prisoner, which makes her feel suddenly tight.

”If it is a newly picked spinach, the normal value of chlorophyll content should be about 0.3mg, and the color of the leaves should be bright green. You can see the color of spinach, chlorophyll at most in 0.2 mg G. The synthesis of chlorophyll can be divided into the following four steps: ① ② ③ ④... ” (Note 1)

”if there is no plant root system to absorb magnesium from the soil, chlorophyll synthesis is impossible. And chlorophyll is always no longer consumed. Therefore, if it is just picked, the chlorophyll content can not be directly reduced by 0.1 MGG. ”

”And...” Cheng Nuo raised a finger and continued.

………………

PS: synthesis steps of chlorophyll:

stage 1: synthesis of 4 molecules of bilinogen from 8 molecules of glutamic acid

stage 2: synthesis of protoporphyrin IX by 4 molecules of bilinogen, and then combine with magnesium to form monovinylprotochlorophyllin a

stage 3: monovinylprochlorophyll A is reduced to chlorophyll ester a by NADPH under light Chlorophyllin A is esterified with phytol to form chlorophyll a

if you can understand it, you can understand it, but if you can't understand it, you can't understand it.
