How to convert oil into sugar for embryo use

What is the mechanism of fat conversion into sugar during seed germination of oil crops
When oil seeds germinate, the fat is first hydrolyzed into fatty acids and glycerol, and then transformed into sugars at the age of one year, which can be used for embryo. The process of transforming fat into sugar is basically an oxidation process, and oxygen should be continuously absorbed at all stages of transformation. Its hydrolysis depends on the activity of lipaseHow do animal cells convert fat into sugar
Fatty acid pass β Acetyl coenzyme A can be formed by oxidation, but fat can not be converted into sugar in large amount, because the hexyl coenzyme a generated by fatty acid decomposition can not be converted into pyruvic acid, that is, the conversion of pyruvic acid is called hexyl coenzyme A. this step of reaction is irreversible
How sugars, fats and proteins are converted
In the case of insufficient energy supply, lipids are oxidized and decomposed, or converted into blood glucose (glucose). When the energy supply of the body is seriously insufficient or pathological changes occur, proteins will be oxidized and decomposed into sugars and fats, or excessive protein intake will also be converted into sugars and fats for storageA brief introduction to the mechanism of fat conversion into sugar during seed germination of oil crops
The germinating fat of oilseed hydrolyzes fatty acid glycerin first and then evolves into sugars for embryo to use the sugar process of fat conversion. Oxygen must be cut off at each stage of basic oxidation process transformation, and its hydrolysis needs the help of lipase to hydrolyze fatty acid glycerin. The former enters the TCA cycle through b-oxidized acetyl coenzyme A, and finally completely oxidizes CO2 waterHow plant fat is converted into sugar during seed germination
After fatty acids in plant cells are oxidized and decomposed into acetyl CoA, succinic acid, glyoxylic acid and malic acid are produced in Glyoxysomes; The succinic acid can be used for sugar synthesis. Glyoxylate cyclers exist only in some plant cells, such as cotyledons and endosperm cells of oilseed plants, and are often associated with mitochondria. ThisHow does fat turn into sugar
In the human body, fat and sugar are mutually transformed. When energy is sufficient, sugar will be transformed into fat for storage. When energy consumption is too large, fat will be transformed into sugar to provide energy
Why does the respiratory quotient decrease when oil seeds are converted into sugars during germination
Sometimes when oil seeds germinate, fat is converted into sugar through glyoxylic acid cycle, which requires oxygen consumption without releasing CO2. RQ is close to 0.5. When fat is exhausted and sugar is used as respiratory substrate, RQ will be close to 1
Can fat be converted into sugar
Fatty acid pass β Acetyl coenzyme A is oxidized to form sugar It should be noted that most of the fat cannot be converted into sugar in the body, because the hexyl coenzyme a generated by fatty acid decomposition cannot be converted into pyruvic acid, that is, the conversion of pyruvic acid is called hexyl coenzyme A, which is irreversibleCan fat turn into sugar
Oils and fats can be hydrolyzed under acid or alkali catalysis It is hydrolyzed to glycerol higher fatty acids under acidic conditions (in vivo) Hydrolyzed to glycerol higher fatty acid salt under alkaline conditions (the hydrolysis reaction of oil under alkaline conditions is called saponification reaction.) Sudan Ⅵ is used to identify fat, and orange oily objects are producedHow fat turns into sugar
In the case of insufficient energy supply, lipids are oxidized and decomposed, or converted into blood glucose (glucose). When the energy supply of the body is seriously insufficient or pathological changes occur, proteins will be oxidized and decomposed into sugars and fats, or excessive protein intake will also be converted into sugars and fats for storage
