Concept
Guanosine triphosphate (GTP) is a nucleotide that serves as an energy source in metabolic processes and as a substrate in signal transduction pathways, particularly in G-protein coupled receptor systems. It plays a crucial role in protein synthesis and cell signaling, acting as a molecular switch in the activation and inactivation of G-proteins.
Concept
Ketosis is a metabolic state where the body uses fat-derived ketone bodies as its primary energy source instead of glucose, typically induced by a low-carbohydrate, high-fat diet. This state can lead to weight loss and improved metabolic health, but requires careful dietary management to maintain and avoid potential side effects.
Concept
Amylopectin is a highly branched polysaccharide and one of the two components of starch, making it less crystalline and more soluble in water compared to amylose. Its structure allows for rapid enzymatic breakdown, which makes it a significant source of energy in the human diet.
