Osaka Gas provides ketone bodies
that the company developed with
its proprietary fermentation technology.
A ketone body is a collective term for D-β-hydroxybutyrate (D-BHB), acetoacetate, and acetone, which are produced inside the human body. It is known that we have D-BHB the most inside our body compared to the other ketones. Under the conditions such as carbohydrates restriction or fasting, triglycerides are broken down and converted to D-BHB in the liver. Then D-BHB transfers into the blood and move around the whole parts of body, where it produces energy.
Once D-BHB is taken up into cells, it tranfers to mitochondria directly and turns out to be energy. It has been reported that D-BHB is preferentially consumed to produce energy over carbohydrate.
It has been reporeted that oral intake of D-BHB increased the blood ketone levels by about 2.5 times as much as that of MCT (medium-chain fatty acids).
