The relationship between sugar metabolism and fat metabolism.

sugars and lipids are hydrocarbon-based
compounds
, and they are very closely related in metabolism. In general, when sugar is available, it can be converted into fat in large quantities, leading to gaining weight.the general steps of
sugar into fat are: sugar is yezed to produce phosphate dihydroxyacetone, phosphate dihydroxyacetone can be reduced to glyceroid, phosphate dihydroxyacetone can continue to form acetone acid through glycolysis, acetone acid oxidized dehydrase into acetyl coenzyme A, acetyl coenzyme A can be used to synthesize fatty acids, and finally by glycelic and fatty acid synthesis of fat.
can be seen that every carbon atom of triglycerides can be transformed from sugar. If you feed livestock with a lot of sugary feed, you can get the effect of fat animals, and many other
microbials
can grow in sugary
culture
-base, in the cell synthesis of various lipids, such as certain
yeast
synthetic fat up to 40% dry weight.the
of
into sugar, first the fat is broken down into glyceal and fatty acids, and then the two are converted to sugar in different ways. Glyceroid is

α-phosphate glyceroid by α phosphate, which is then converted into phosphate dehydroxy acetone, which is converted into sugar by sugar isogenation. Fatty acids β-oxidation to produce acetyl coenzyme A.
Acetyl Coenzyme A formed in plants or microorganisms is produced by acetaldehyde acid cycle to form amber acid, amber acid is then cycled by triacetic acid to form oxalacetic acid, oxalacetic acid can be de-acetylene to form acetone acid, and then through the action of glycogenic action can form sugar. However, there is no acetaldehyde acid cycle in humans and animals, and in general, acetyl coenzyme A is oxidized into CO2 and H2 O through the triacetic acid cycle, not into sugar.
therefore, for animals, only the glycene portion of the fat can be converted into sugar, and glycerate accounts for a relatively small amount of fat, so the amount of sugar produced is relatively small. However, the oxidation of fatty acids can reduce the demand for sugar, so that when the supply of sugar is insufficient, fat can replace sugar to provide energy, so that blood sugar concentration does not drop too much. It can be seen that not only can sugar and fat be converted to each other, but also very closely related to each other's alternative energy supply..
