Uric acid is a product of purine metabolism and plays a crucial role in the body's antioxidant defense system by scavenging free radicals. It helps regulate oxidative stress and inflammation, which can contribute to various diseases. Additionally, uric acid levels in the blood can serve as a marker for certain health conditions, such as gout and kidney dysfunction. However, excessive uric acid can lead to health issues, indicating the importance of maintaining balanced levels.

What are the substrate and product of urate oxydase?
Urate oxidase catalyzes the oxidation of uric acid (a product of purine metabolism) to 5-hydroxyisourate. This enzyme is absent in many primates (including humans).
What is the cause of kidney stones?
Most kidney stones are composed of uric acid, which is a byproduct of the digestion of protein. Kidneys filter uric acid out of the blood, and if the concentration of uric acid is too high, you can get a precipitation of uric acid into a solid form, since the solubility of uric acid is moderate, but not high. Solid uric acid is then a stone, a solid object inside the kidney, where it causes trouble until it passes out with the urine.
What is the product of oxidation of d gulose?
D-Gulonic acid
Uric acid - blood?
DefinitionUric acid is a chemical created when the body breaks down substances called purines. Purines are found in some foods and drinks, such as liver, anchovies, mackerel, dried beans and peas, beer, and wine.Most uric acid dissolves in blood and travels to the kidneys, where it passes out in urine. If your body produces too much uric acid or doesn't remove enough if it, you can get sick. High levels of uric acid in the body is called hyperuricemia.This test checks to see how much uric acid you have in your blood.See also: Uric acid - urineHow the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.A laboratory specialist checks the blood sample for uric acid.How to prepare for the testYou should not eat or drink anything for 4 hours before the test unless told otherwise. Your doctor may also tell you to stop taking any drugs that may affect the test results. NEVER stop taking any medicine without talking to your doctor.Drugs that can increase the level of uric acid in your body include:AlcoholAscorbic acidAspirinCaffeineCisplatinDiazoxideDiureticsEpinephrineEthambutolLevodopaMethyldopaNicotinic acidPhenothiazinesTheophyllineDrugs that can decrease the level of uric acid in your body include:AllopurinolAzathioprineClofibrateCorticosteroidsEstrogenGlucoseGuaifenesinMannitolProbenecidWarfarinWhy the test is performedThis test is done to see if you have high levels of uric acid in your blood. High levels of uric acid can cause gout or kidney disease.Your doctor may also order this test if you have had or are about to have certain types of chemotherapy. Rapid weight loss, which may occur with such treatments, can increase the amount of uric acid in your blood.Normal ValuesNormal values fall between 3.0 and 7.0 mg/dL.Note: Normal values may vary slightly from laboratory to laboratory.What abnormal results meanGreater-than-normal levels of uric acid (hyperuricemia) may be due to:AcidosisAlcoholismDiabetesGoutHypoparathyroidismLead poisoningLeukemiaNephrolithiasisPolycythemia veraRenal failureToxemia of pregnancyPurine-rich dietExcessive exerciseChemotherapy-related side effectsLower-than-normal levels of uric acid may be due to:Fanconi syndromeWilson's diseaseSyndrome of inappropriate antidiuretic hormone (SIADH) secretionLow purine dietAdditional conditions under which the test may be performed:Chronic gouty arthritisInjury of the kidney and ureterReferencesTerkeltaub R.

What is the scientific name for Vitamin C?
There are two main types of Vitamin D ( calciferol) : ergocalciferol (vitamin D2) and activated cholecalciferol (vitamin D3).
Oxidation of D-arabinose?
The oxidation of D-arabinose involves the conversion of its alcohol functional groups to carbonyl groups, leading to the formation of D-arabinonic acid. This reaction typically occurs under the influence of oxidizing agents, such as nitric acid or enzymes like aldose oxidase. The process results in changes to the sugar's physical and chemical properties, which can be significant in biochemical pathways and applications in food chemistry. Additionally, the oxidation can affect the sugar's reactivity in further chemical reactions.
What acid is formed in the digestion of protein?
Amino Acid! ;D
Does sunny d have acid?
yes sunny d has acid every thin we drink has acid in i5t even water
What is d in DNA?
Deoxyribonucleic acid
Gout and elbow?
Absolutely I am going through it right now. Its Red wine that triggers it in me. Swapped Beer for Cider and attacks were less frequent. Reality check now-time for major lifestyle change. More exercise (im not overweight) will strengthen muscles and look to take vitamin D.
Is a weak acidA.H2SO4 (Sulfuric acid) B.HCl (Hydrochloric acid) C.HNO3 (Nitric acid) D.CH3COOH (Acetic acid)?
Acetic acid is a weak acid.
What are the two main types of lactic acid?
The two main types of lactic acid are L-lactic acid and D-lactic acid. They are optical isomers, meaning they have the same chemical formula but differ in the arrangement of atoms. L-lactic acid is the form produced in the human body during strenuous exercise, while D-lactic acid is produced by certain bacteria.
