Damage by glycation results in stiffening of the collagen in the blood vessel walls, leading to high blood pressure, especially in diabetes. [11] Glycations also cause weakening of the collagen in the blood vessel walls, [ 12 ] which may lead to micro- or macro-aneurysm; this may cause strokes if in the brain.
Phosphofructokinase-2 (6-phosphofructo-2-kinase, PFK-2) or fructose bisphosphatase-2 (FBPase-2), is an enzyme indirectly responsible for regulating the rates of glycolysis and gluconeogenesis in cells. It catalyzes formation and degradation of a significant allosteric regulator, fructose-2,6-bisphosphate (Fru-2,6-P 2) from substrate fructose-6 ...
Fru-2,6-P 2 strongly activates glucose breakdown in glycolysis through allosteric modulation (activation) of phosphofructokinase 1 (PFK-1).Elevated expression of Fru-2,6-P 2 levels in the liver allosterically activates phosphofructokinase 1 by increasing the enzyme’s affinity for fructose 6-phosphate, while decreasing its affinity for inhibitory ATP and citrate.
PFK1 is allosterically activated by a high concentration of AMP, but the most potent activator is fructose 2,6-bisphosphate, which is also produced from fructose-6-phosphate by PFK2. Hence, an abundance of F6P results in a higher concentration of fructose 2,6-bisphosphate (F-2,6-BP). The binding of F-2,6-BP increases the affinity of PFK1 for ...
Insulin resistance desensitizes insulin receptors, preventing insulin from lowering blood sugar levels. [38] The leading cause of hyperglycemia in type 2 diabetes is the failure of insulin to suppress glucose production by glycolysis and gluconeogenesis due to insulin resistance. [39] Insulin normally inhibits glycogenolysis, but fails to do so ...
A new analysis of 184 countries linked 2.2 million cases of type 2 diabetes and 1.2 million cases of cardiovascular disease to sugar-sweetened beverages. Sugary Drinks Linked to Diabetes, Heart ...
Consuming a drink with erythritol — an artificial sweetener used to add bulk to stevia and monk fruit and to sweeten low-carb keto products — more than doubled the risk of blood clotting in 10 ...
The absence of fructokinase results in the inability to phosphorylate fructose to fructose-1-phosphate within the cell. As a result, fructose is neither trapped within the cell nor directed toward its metabolism. [11] Free fructose concentrations in the liver increase and fructose is free to leave the cell and enter plasma.
