Subsequently, question is, What causes hyperuricemia?
Causes of Hyperuricemia
Hyperuricemia can occur as a result of your body producing too much uric acid or getting rid of too little. You have a purine-rich diet. Foods high in purine include some organ meats, game, herrings and a few other types of seafood, and beer.
In respect to this, Can starvation cause hyperuricemia?. A very low calorie diet lacking in carbohydrates can induce extreme hyperuricemia; including some carbohydrate (and reducing the protein) reduces the level of hyperuricemia. Starvation also impairs the ability of the kidney to excrete uric acid, due to competition for transport between uric acid and ketones.
Hereof, Which amino acid is required for the conversion of UTP to CTP by CTP synthase?
Antibodies to Rods and Rings
CTPS1 is a 67-kDa protein that catalyzes the conversion of uridine triphosphate into cytidine triphosphate (CTP), which is essential in regulating cellular proliferation and plays a substantial role in nucleic acid and phospholipid biosynthesis.
How is uric acid produced?
Uric acid is a waste product found in blood. It's created when the body breaks down chemicals called purines. Most uric acid dissolves in the blood, passes through the kidneys and leaves the body in urine. Food and drinks high in purines also increase the level of uric acid.

Eggs are low in purines but consume them in moderation (Health Promotion Board recommends consuming up to four eggs per week). Essential fatty acids found in cold-water fish such as tuna can reduce gout inflammation.
Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. ... In nucleic acids, three types of nucleobases are pyrimidine derivatives: cytosine (C), thymine (T), and uracil (U).
CTP is formed by CTP synthetase by transferring an amino group from glutamine to UTP (Figure 3). Pyrimidine biosynthesis is regulated by feedback inhibition of the first enzyme carbamoyl phosphate synthetase by the end products UMP, UDP, and UTP of the pathway.
UMP is converted to uridine-5′-triphosphate (UTP) by two sequential reactions with ATP involving two kinases (UMP and UDP kinases). UTP is aminated, by a reaction catalyzed by a CTP synthase, using ammonia derived from l-glutamine as source of nitrogen, to yield CTP.
Fasting has been reported to increase uric acid in the literature. Gumaa et al. reported the linear increase of serum uric acid level with the duration of Ramadan fast among 16 volunteers . Runcie and Thomson also found the occurrence of hyperuricemia in 42 obese patients treated with total fasting .
Uric acid levels increase with dehydration, mainly because there is less water in the body and the blood becomes more concentrated [32, 33]. Levels return back to normal after hydrating.

Bananas are low in purines and high in vitamin C, which make them a good food to eat if you have gout. Changing your diet to include more low-purine foods, like bananas, can lower the amount of uric acid in your blood and reduce your risk of recurrent gout attacks.
Cytidine triphosphate (CTP) is an allosteric inhibitor representing a classic case of feedback inhibition whereby the end product of a biosynthetic pathway inhibits an enzyme catalyzing a reaction at the beginning of the pathway.
Compulsory Third Party (CTP) Insurance, also known as Green Slip in New South Wales, provides cover for people who may be injured or killed in a motor vehicle accident involving your vehicle. ... It doesn't cover the cost of damage to vehicles and property, nor does it cover damage to — or loss of — your own vehicle.
In the yeast Saccharomyces cerevisiae, the reaction product CTP is an essential precursor of all membrane phospholipids that are synthesized via the Kennedy (CDP-choline and CDP-ethanolamine branches) and CDP-diacylglycerol pathways. The URA7 and URA8 genes encode CTP synthetase in S.
The pyrimidines in DNA are cytosine and thymine; in RNA, they are cytosine and uracil. Purines are larger than pyrimidines because they have a two-ring structure while pyrimidines only have a single ring.
Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. The main difference between purines and pyrimidines is that purines contain a sixmembered nitrogencontaining ring fused to an imidazole ring whereas pyrimidines contain only a sixmembered nitrogencontaining ring.
Pyrimidines. Cytosine is found in both DNA and RNA. Uracil is found only in RNA. Thymine is normally found in DNA.
Chicken is mostly a moderate-purine food, but the amount of purines in cuts do range from low to very high. People with gout are advised to avoid organ meats like chicken liver and only eat moderate-purine foods in sensible portions.
The studies concluded that lemons and lemon juice might be a useful remedy to help treat gout along with medications and other dietary changes. Lemon juice may also help prevent gout in people with high uric acid levels.
Eggs are a good protein source for people with gout, because eggs are naturally low in purines.
