For identification purposes the carbonyl and adjacent alcohol functions will form phenylhydrazine derivatives known as osazones, which give characteristic melting points and exhibit definite crystalline structure. It should be noted that glucose , fructose and mannose yield the same osazone since the difference in structure and configuration about carbon atoms 1 and 2 are abolished.

Your specific gravity test was low what does it mean?
Before answering your question, do you produce large amount of urine (polyuria)? LOW Specific Gravity test (1.003-1.009 [I think]) means that you have low amount of particles inside your urine. It is clinical significance serious, it may indicate type I diabetes. (you also may have polyuria) If it is just normal, you just drinking a lot of water (you also may have polyuria)
What are some of the types of clinical trial designs?
Clinical study design is the formulation of trials and experiments in medical and epidemiological research. Many of the considerations here are shared under the more general topic of design of experiments but there can be others, in particular related to patient confidentiality and ethics.
When does a scientist test a hypothesis?
You test a hypothesis after you form it. But lets go over the scientific method anyway. You start with a situation, then you come up with a question, then a hypothesis: there are two kinds of hypothesis, null and alternate, null means that the results dictate that the treatment shows no Significance, where alternate shows that the groups have difference, which is significance. You test the hypothesis in an experiment, and there are many different tests that you can apply to the DATA you collect.
What is clinical attutude or clinical approach?
A clinical approach involves the use of empirical information and treament.
When was Clinical Case Studies created?
Clinical Case Studies was created in 2002.
Why is glacial acetic acid used in osazone test?
Glacial acetic acid is used in the osazone test to help dissolve and react with the osazone crystals formed. It also helps in providing an acidic environment which is necessary for the reaction to occur effectively.
Why we use sodium acetate in the osazone test?
Sodium acetate is used in the osazone test to adjust the pH of the solution. It helps to create a suitable environment for the reaction between the sugar and phenylhydrazine, which forms the osazone crystals used to identify specific sugars. The acidic conditions provided by sodium acetate also help in the formation of the osazone derivative.
What Reagents are used in osazone test?
The reagents used in the osazone test are phenylhydrazine and acetic acid. These reagents are used to detect reducing sugars such as glucose by forming characteristic needle-like crystals called osazones.
Osazone test for carbohydrates?
The Osazone test is a chemical test used to detect the presence of reducing sugars like glucose, fructose, and maltose in a carbohydrate sample. During the test, the reducing sugar reacts with phenylhydrazine to form a crystalline compound known as an osazone. This compound can then be visually identified under a microscope to confirm the presence of reducing sugars in the sample.
How many phenylhydrazines are required in osazone reaction?
Two phenylhydrazines are typically required in the osazone reaction, which is a chemical test used for identifying and characterizing reducing sugars. In this reaction, the aldehyde or ketone group of the sugar reacts with phenylhydrazine to form a crystalline osazone derivative.

What is the importance of phenylhydrazine test?
The phenylhydrazine test is important in identifying the presence of sugars, specifically aldose sugars in a sample. It forms osazone crystals with aldose sugars that are characteristic and can help determine the type of sugar present. This test is commonly used in biochemical and food analysis to detect the presence of reducing sugars.
What does a clinical correlation mean from a stress test?
A clinical correlation from a stress test involves interpreting the test results in conjunction with the patient's symptoms, medical history, and other diagnostic tests to arrive at a diagnosis or treatment plan. It helps the healthcare provider determine the significance of abnormal findings on the stress test in relation to the patient's overall health condition.
3 reasons why the osazone test can be used in identification of sugars?
The osazone test can help identify the specific type of sugar present in a sample by forming distinct crystals with characteristic shapes and colors. It is a simple and reliable method that can distinguish between different sugars based on their unique osazone derivatives. The test is sensitive and can detect even small amounts of sugars, making it useful in various applications such as food science and biochemistry.

Why maltose gives sunflower shaped crystals in osazone test?
Maltose forms sunflower-shaped crystals in the osazone test because its structure allows for multiple hydroxyl groups to participate in the reaction with phenylhydrazine. The specific arrangement of these hydroxyl groups on maltose leads to the formation of complex crystalline structures, giving rise to the characteristic sunflower appearance.
What are two aldotetroses that yield the same osazone on reaction with phenyl hydrazine?
Ribose and Arabinose are two aldohexoses that yield the same osazone on reaction with phenyl hydrazine.
