Ketogenesis

Part of speech: noun

Pronunciation: /ˌkiːtəʊˈd͡ʒɛnɪsɪs/

Definitions

1. The biochemical transformation encompasses the creation of ketone bodies through the breakdown of fatty acids in response to decreased carbohydrate intake
2. This process refers to how the body generates energy by converting fat into ketones when glucose is not readily available
3. The metabolic process involves the synthesis of ketone bodies from fatty acids, serving as an alternative energy source when carbohydrates are scarce

Etymology: Ketogenesis is a plain technical coinage, built from two pieces of modern scientific vocabulary rather than from any ancient word. The first part, "keto-", comes from "ketone", the name chemists gave to a family of organic compounds containing a carbonyl group. The second part, "-genesis", is a classical Greek suffix meaning "origin" or "production", which has been used for centuries to name processes that create something, as in "biogenesis" or "osmogenesis." Put together, the term describes the making of ketone bodies, the molecules the liver produces from fatty acids when the body has little carbohydrate available. The word therefore names a metabolic process rather than a substance, and its parts are a literal description of that process: the production of ketones.
