beta-oxidation
[ˈbeɪtə ˌɑːksɪˈdeɪʃən]
nounfemininepl: beta-oxidações
beta-oxidação
1. A metabolic process in which fatty acids are broken down by two carbon units at a time to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are used for ATP production
Beta-oxidation occurs primarily in the mitochondria and peroxisomes of cells, providing energy by breaking down fatty acids.
A beta-oxidação ocorre principalmente nas mitocôndrias e peroxissomos das células, fornecendo energia pela degradação de ácidos graxos.
2. The cyclical process of oxidative degradation of fatty acids, removing acetyl units sequentially from the carboxyl end of the chain
The four-step cycle of beta-oxidation repeats until the fatty acid is completely metabolized.
O ciclo de quatro etapas da beta-oxidação se repete até que o ácido graxo seja completamente metabolizado.
Beta-oxidation is a fundamental concept in biochemistry taught in medical schools, nutrition programs, and biological sciences across both Brazil and the USA. The term is highly technical and primarily used in academic and professional scientific contexts. In Brazil, it appears frequently in biochemistry courses and nutritional science programs, particularly when discussing obesity, metabolic disorders, and energy metabolism.
