Metabolism of sugars: A window to the regulation of glucose
Background &aims: Dietary sugars are absorbed in the hepatic portal circulation as glucose, fructose, or galactose. The gut and liver are required to process fructose and galactose into glucose, lactate, and fatty acids. A high sugar intake may favor the development of cardio-metabolic diseases by inducing Insulin resistance and increased concentrations of …

Metabolism – It's What Keeps You Going
The meaning of the word "metabolism" is very simple, yet few people seem to understand what it is and what it does. Metabolism is the set of chemical processes that take place in living organisms to sustain life. On a microscopic scale, the reactions and processes that maintain cellular health are referred to as cellular metabolism.

Enzymes allow discrete reactions to occur, which when combined give the same overall effect as combustion, but in a controlled fashion. In this review, we will discuss the energy of reactions, the role of metabolic enzymes, key metabolic pathways, and then the vital organelles for energy generation.
