Introduction
The energy production is an essential live performance. Ketone synthesis occurs as a vital approach to survive and protract human lives on the occasion for the body is isolated from regular energy source supplements or normal energy metabolism pathways are disturbed, for instance, prolonged starvation, uncontrolled diabetes, and extreme fat and inadequate carbohydrate dietary intake. The Liver mainly assumes responsibility of ketone body production named ketogenesis from fatty acid during under the terms of low glucose level. Produced ketone bodies are acetone, acetoaceticacid and β-hydroxybutyric acid which of two water soluble components are passed to organs such as brain, skeletal muscle, myocardium and kidney through blood stream to utilize as energy sources. Although ketogenesis is vital for brain as brain can only use either glucose or ketone body as energy sources in an emergent condition, excessively elevated ketone bodies level in the blood can cause acidosis which can cause severe conditions of patients such as comatose. Therefore, significant ketosis should be taken appropriate treatment is needed when ketogenesis is accelerated.

Ketone body producution in the liver
Ketone body is generated from fatty acids at the mitochondria in the liver when glycogen is depleted in the cells. First of all, β-adrenergic catecholamines activates lipolysis to supply fatty acids from adipose tissue during prolonged fasting or low plasma insulin level. Adiposities releases fatty acids into blood by hormone-sensitive lipase. Secondly, fatty acids are formed into long-chain fatty acyl CoA by synthase of fatty acyl CoA. Thirdly, CPT 1 (carnitine palmityl transferase I) catalyses the fatty acyl CoA to carnitine for the purpose ...

...ect on ketone body production. Ketone bodies have important role of body as energy sources specifically in emergent condition due to blocked glucose supply in the body. Fatty acids are normally metabolised through citric acid cycle after it is formed into acetyl CoA though, it is used for ketogenesis;β-oxidisation is occur to generate ketone body during glucose supply is insufficient. Ketone bodies are vital in terms of surviving with little or non energy source supply and saving nitorogen loss from the body. Ketone bodies produced in the liver are not used in the liver though it is used as primal energy source in the brain, skeletal muscle, heart and kidneys. However, prolonged ketogenesis can cause ketoacidosis which can expose the body to danger causing dehydration or comatose. Therefore ketone production seems to be controlled by several hormones and enzymes.
