Urine ketone body
concentrations are usually two to four times higher than blood concentrations, whereas, milk ketone body
concentrations are usually 40 to 50 per cent of blood concentrations.
Ketogenic diet, which is very low in sugars and high in fat, forces neurons to switch from their customary fuel of glucose to a type of fat byproduct called a ketone body
In a study of 51 small-for-gestational-age (SGA) and 22 large-for-gestational-age (LGA) neonates, blood glucose and ketone body
levels were measured for the first postnatal week to assess neonatal metabolic adaptation, the investigators said (Pediatrics [online] 109, 2002; www.
Because the [beta]-hydroxybutyrate dehydrogenase concentration is exceptionally high in the liver , and these two ketones penetrate cell membranes, the ketone body
ratio in the hepatic venous blood can reflect that in the liver mitochondria.
