Feline hepatic lipidosis, also known as feline fatty liver syndrome, is one of the most common forms of liver disease of cats. [1] The disease officially has no known cause, though obesity is known to increase the risk. [2] The disease begins when the cat stops eating from a loss of appetite, forcing the liver to convert body fat into usable ...
The Cahill cycle, also known as the alanine cycle or glucose-alanine cycle, [1] is the series of reactions in which amino groups and carbons from muscle are transported to the liver. [2] It is quite similar to the Cori cycle in the cycling of nutrients between skeletal muscle and the liver. [ 1 ]
In similar manner, in muscles the use of pyruvate for transamination gives alanine, which is carried by the bloodstream to the liver (the overall reaction being termed glucose-alanine cycle). Here other transaminases regenerate pyruvate, which provides a valuable precursor for gluconeogenesis.
Now there have been documented cases of cats that get sick and survive the infection and even those that never show clinical signs at all. [2] [5] [9] [10] Cats cannot catch the infection from another cat directly without being bitten by a tick. [citation needed] The life cycle of the protozoa has a tissue phase and an erythrocytic (red blood ...
Under aerobic conditions, the pyruvate is transported from the cytosol to the mitochondrion, where further energy can be extracted through the citric acid cycle (CAC) [citation needed] The liver can also create glucose (gluconeogenesis, see below); during times of low carbohydrate supply from the digestive system, the liver creates glucose and ...
Liver failure is the inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology. Two forms are recognised, acute and chronic (cirrhosis). [ 1 ] Recently, a third form of liver failure known as acute-on-chronic liver failure ( ACLF ) is increasingly being recognized.
Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
The glucose cycle can occur in liver cells due to a liver specific enzyme glucose-6-phosphatase, which catalyse the dephosphorylation of glucose 6-phosphate back to glucose. Glucose-6-phosphate is the product of glycogenolysis or gluconeogenesis , where the goal is to increase free glucose in the blood due body being in catabolic state.
