Is natural carotene chemically synthetic

It is synthesized within the organism.

Hello dear <>

We'll be happy to answer for you. The essential differences between pure natural carotene in plants and solvent-extracted carotene are:1

The extraction method is different: natural carotene is a part of the ingredient that is naturally produced in plants and retained in the first major processes such as food processing. Solvent-extracted carotene, on the other hand, is extracted from plants through specific chemical methods.

2.Difference in purity and content: The carotene extracted by the solvent will be separated and concentrated during the extraction process, so the carotene content in it may be higher, and at the same time, this also leads to a relatively high purity of the carotene.

In contrast, all-natural carotene contains some other plant components, and its carotene content and purity may be lower. 3.Assessment of human health effects:

Although carotene is ubiquitous and safe in plants, the evaluation of solvent-extracted carotene on human health still needs to be systematically and rigorously studied. Additionally, some people may have allergies or adverse reactions to specific chemicals.

1. - Carotene is a carotenoid substance that can be found in plants, which assists light and action. - The main role of carotene is to provide the natural pigment orange, red, yellow and green of water nuts and vegetables in water.

2. Long-term use will produce a certain degree of toxicity to the human body, and it will cause irreversible lesions to the human body, while natural extract-carotene is easy to be absorbed by the human body.

Carotene is the main source of vitamin A, mainly in three forms, the most important of which is - carotene.

Chemical formula (C40H56).

1) Carotene is an orange crystal, a fat-soluble substance, its chemical properties are relatively stable, insoluble in water, slightly soluble in ethanol, soluble in organic solvents such as petroleum ether

2) The most commonly used method of extracting carotene is extraction, that is, the carotene is dissolved in an organic solvent, and after evaporating the solvent, the carotene is obtained The general process of operation is: carrot crushing and drying Extraction Filtration Concentration of carotene

3) High temperature will decompose carotene, in the process of heating and drying, the temperature and time should be controlled

4) Carotene was obtained by extraction, identified by paper chromatography, and compared with standard samples

5) The organic solvent for extracting carotene should have a high boiling point, be able to fully dissolve carotene, and be incompatible with water The water content of raw material particles will also affect the efficiency of extraction, and the extraction degree of organic solvent will be reduced due to the presence of water

The human body cannot synthesize carotenoids on its own, and must be ingested through the outside world; However, carotenoids are found in low amounts in many plants and are difficult to synthesize chemically, mainly through biosynthesis. Biosynthesis pathwayCarotenoid biosynthesis can be synthesized by different pathways, from acetyl-Coa through the hydroxymethylglutaryl-Coa pathway in the endoplasmic reticulum of fungal and plant cell cytosols. It is synthesized from phosphoglyceraldehyde and pyruvate by the 1-deoxyxylulose-5-phosphate pathway in bacteria and plant plastids.

The formed isoprenylpyrophosphate is condensed several times to form the first carotenoid octahydrolycopene, which is then converted into other carotenoids by dehydrogenation, cyclization, hydroxylation, epoxidation, etc. Through the synthesis process diagram, it can be clearly seen that lycopene, carotene, zeaxanthin, and anthoxythanthin are all intermediate forms in the biosynthesis process of carotenoids, and astaxanthin (astaxanthin) is the terminal form of carotenoid biosynthesis. Carotenoids biosynthesize these pigments mainly to protect the unsaturated fatty acids in their seeds and reserve energy for the reproduction of the next generation.

Therefore, with the continuous advancement of the synthesis process, each level of these carotenoids in the synthesis process in the figure is stronger than the antioxidant activity of the previous level, for example, the antioxidant activity of astaxanthin is 10 times that of carotene and 200 times that of lutein.

Biosynthetic process.

Its biosynthesis process is as follows: acetyl coa, isomethyl pyrophosphate (C5), scab cattle, pyropyrophosphate (C20), colorless carotenoids, chlorophyllene (phy toene), etc

Carotene, -carotene, etc. become retinol (vitamin A) and retinaldehyde (vitamin A aldehyde) in animals, which are related to vision. During photosynthesis, the light energy absorbed by carotenoids is transferred to chlorophyll which is used to drive the photochemical process. For bacteria, it is related to its phototropism.

Carotenoids are effective inactivators of an important activation state of O2, preventing photoinactivation and photodestruction of organisms. The carotenoids of bacteria include bacteriogen, -carotene, -carotene and zeaxanthin, etc., in addition, spirilloxanthin, spheroidenone, and spheroidenone, which are obtained from red sulfur flavours and red non-sulfur flavours with photosynthesis. okenone, and chlorobactene contained in green sulfur flavonium bacteria.
