What is the chemical structure of 3-monoiodine-L-tyrosine?
L-lactic acid is an organic compound with a chemical formula of $C_3H_6O_3 $. This compound contains a carboxyl group and a hydroxy group, and belongs to an α-hydroxy acid.
In terms of its chemical structure, the central carbon atom is connected to a methyl group ($- CH_3 $), a hydroxy group ($-OH $), a carboxyl group ($-COOH $) and a hydrogen atom ($H $). Because the central carbon atom is connected to four different groups, L-lactic acid has chirality, and there are two enantiomers, namely L-lactic acid and D-lactic acid. The naturally occurring lactic acid is mostly L-lactic acid, and the lactic acid produced by the human metabolic process is also dominated by L-lactic acid. The carboxyl group of L-lactic acid gives it acidic properties, which can be partially ionized in water to release hydrogen ions ($H ^ + $). The hydroxyl group can participate in many chemical reactions, such as esterification reaction, that is, the reaction between the hydroxyl group and the carboxyl group under specific conditions to form an ester compound and water. Because of its carboxyl and hydroxyl groups, L-lactic acid can undergo polycondensation reaction, and many L-lactic acid molecules dehydrate and condense with each other to form polylactic acid (PLA). As a degradable polymer material, polylactic acid is widely used in packaging, medical and other fields.
In short, the unique chemical structure of L-lactic acid makes it have a variety of chemical properties and a wide range of application prospects.

How is 3-monoiodine-L-tyrosine metabolized in the human body?
L-cysteine is in the human body, and its metabolism process is delicate and complicated, just like the wonders of heaven.
L-cysteine is absorbed by the stomach. The function of the stomach, such as sieving, can make L-cysteine pass through the intestinal wall and enter the blood circulation, just like a boat traveling in a river, flowing smoothly around the body.
After entering the blood, L-cysteine travels with the blood to various tissues and cells. In cells, it can be used as a raw material for synthesizing proteins. Protein is the cornerstone of life. L-cysteine, with its unique structure, participates in the construction of proteins, just like masonry added to a building, indispensable. And L-cysteine is rich in sulfur, which plays an important role in the stability of the spatial structure of proteins and can maintain the inherent form and function of proteins.
Furthermore, L-cysteine can be metabolized into glutathione. Glutathione has antioxidant properties, like a shield, which can resist the invasion of free radicals on cells. Free radicals, such as those in troubled times, often cause cell damage, while glutathione can capture and destroy them, protecting the safety of cells. Its generation process involves the catalysis of a variety of enzymes, which are interlocking, just like the ingenuity of heaven.
Not only that, L-cysteine also plays a role in the detoxification process of the human body. Liver, the detoxification of the human body, L-cysteine can help the liver dissolve toxins. Poisons enter the body, such as enemy territory, L-cysteine can combine with it, change its properties, make it easy to excrete from the body, and maintain the health of the body.
L-cysteine is involved in human metabolism, which is related to protein synthesis, antioxidant defense, and detoxification. It is interlocking and subtle. It is actually a subtle embodiment of heaven's creation and is indispensable for maintaining the normal operation of life.
What is the approximate market price of 3-monoiodine-L-tyrosine?
L-butyric acid, if the market is large, it is determined by the market. It depends on the supply and demand of the product, quantity, place and city.
If the product is high-quality, the seller will be high, and the seller will be low-cost. High-quality L-butyric acid requires a high-quality method, so its cost is high, and its sales price is also high. On the contrary, if the content is high, the method is easy, the cost is low, and the market price is also low.
The quantity is also due to factors. If the seller asks for a large quantity, the merchant may be promoted, and the discount will be given, and the price will be lower or lower. If the seller asks for a small amount, the merchant will be lower, and the price will be higher.
In the land, the business is prosperous, and the demand may be prosperous, but the rent and other costs are also high, or not low. In the land where the demand is small, the cost may be low, or there may be a decrease.
Furthermore, the supply and demand of the city are to the point of demand. More demand and less supply are necessary; more supply and less demand are necessary, and the demand must be suppressed. If the demand for L-butyric acid increases greatly in one area, and the amount of L-butyric acid does not increase, it must be increased.
In normal circumstances, the market for L-butyric acid ranges from 10 yuan to 100 yuan per gram. Then the general price is low, and the cost is low, according to the above reasons.
What are the production methods of 3-monoiodine-L-tyrosine?
L-lactic acid is an important organic acid and is widely used in food, medicine, chemical industry and other fields. There are many production methods. In the context of "Tiangong Kaiwu", it can be described as follows:
First, fermentation method. This is a commonly used method. Carbohydrates such as carbohydrates and starches are used as raw materials to convert L-lactic acid through microbial fermentation. As in the past, farmers knew that grains and other grains were used as starting materials and fermented by specific microorganisms under conditions such as suitable temperature and humidity. At that time, although the microbial mechanism was not as completely clear as it is today, a suitable fermentation environment was explored through experience. Common fermentation microorganisms include lactic acid bacteria, which cleverly metabolize sugars into L-lactic acid in an anaerobic or micro-oxygen environment. And the fermentation method can produce high-purity L-lactic acid, which meets the strict requirements of many fields.
Second, enzymatic method. With the help of the catalytic action of specific enzymes, the substrate is converted into L-lactic acid. Among them, the enzyme is highly specific and efficient. For example, enzymes that can have specific catalytic activity for specific substrates are selected to precisely catalyze the reaction process. Although there is no advanced technology for purification and application of enzymes like modern ones in ancient times, there are organisms or substances rich in such enzymes in nature, which can be used for catalysis by simple treatment, and can avoid the complex side reactions that may occur in chemical synthesis, making the product more pure.
Third, chemical synthesis method. L-lactic acid is prepared from acetaldehyde and hydrocyanic acid through a series of chemical reactions. However, this method was limited in ancient times due to the toxicity of the raw materials, dangerous operation, and harsh reaction conditions. However, in principle, the target product can be synthesized by controlling the chemical reaction conditions, such as temperature, pressure, catalyst, etc. However, compared with fermentation methods and enzymatic methods, the chemical synthesis method requires fine separation to obtain high-purity L-lactic acid.
