In 1945, a woman named Beulah Hunter, who was 25 at the time, gave birth to a healthy, normal daughter named Penny Diana after the record-breaking pregnancy. According to the New Health Guide, the length of the pregnancy was verified by her menstrual cycle and the date of her positive pregnancy test.
In chemistry, a ketone (alkanone) /ËkiËtoÊn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond).
Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides). The main ketone bodies used for energy are acetoacetate and Î²-hydroxybutyrate, and the levels of ketone bodies are regulated mainly by insulin and glucagon.
