Molecules are chemicals. A particular chemical posses a characteristic feature of forming an unique product when it undergoes chemical reaction along with another chemical. So to identify the chemical "A", one may use chemical "B" or "X" to react with chemial "A" to identify the formation of a product "AB" or "AX". This may many times evident by changes in color.

What lab tests are used to test for the presence of protein?
Common lab tests used to test for the presence of protein include a serum protein electrophoresis (SPEP) test, a urine protein test, and a total protein test. These tests can help diagnose conditions such as kidney disease, liver disease, or protein deficiencies.
Biochemical tests for identification of cyanobacteria?
Common biochemical tests for identifying cyanobacteria include testing for the presence of chlorophyll a, phycocyanin, and phycoerythrin pigments. Additionally, assessing the ability to fix atmospheric nitrogen (nitrogen fixation) and conducting tests for the presence of gas vesicles are also used for identification purposes. Molecular techniques like PCR and sequencing can also be employed for more accurate identification.
What is the difference between anti-A and anti-B serum in blood typing tests?
Anti-A serum is used to detect the presence of A antigens on red blood cells, while anti-B serum is used to detect the presence of B antigens. This helps determine a person's blood type in blood typing tests.
What are tests for proteins?
How to test for protein - The Biuret test1. Add Sodium hydroxide to a 1% solution of albumen (the protein in egg white) or the ground food you want to be tested for protein2. Then add 1% copper sulphate solution3. If protein is present the solution will go purple
Biochemical tests are used to determine what?
Biochemical tests are used to determine the presence of specific molecules, such as proteins, enzymes, or metabolites, in a sample. These tests help to diagnose diseases, monitor treatment, and assess overall health status based on the chemical reactions happening in the body.
How is amyloidosis diagnosed?
Blood and urine tests can reveal the presence of amyloid protein, but tissue or bone-marrow biopsy is necessary to positively diagnose amyloidosis.

What lab tests can be done to test for the pressence of organic molecules?
Common lab tests to detect the presence of organic molecules include chromatography, mass spectrometry, and infrared spectroscopy. These tests can help identify different types of organic compounds based on their unique properties and interactions with specific detection methods.
What is iodine in the presence of when it turns black?
When iodine turns black, it is usually in the presence of starch. This forms a blue-black complex that is used in various chemical tests to detect the presence of starch in a substance.
What are the different ways to test the purity of water?
There are several methods to test the purity of water, including chemical tests, physical tests, and biological tests. Chemical tests involve analyzing the levels of specific substances in the water, such as pH, dissolved solids, and contaminants. Physical tests measure properties like turbidity, temperature, and odor. Biological tests assess the presence of bacteria and other microorganisms in the water. These tests help determine if the water is safe for drinking and other uses.
How do you determine a strach?
A starch is a complex carbohydrate made up of long chains of sugar molecules. It can be determined using various chemical tests such as iodine test, which turns blue-black in the presence of starch, or by using enzymatic methods to break down starch into individual sugar units for quantification.
What is iodine used to find?
Iodine is used to find the presence of starch. When iodine comes in contact with starch, it forms a blue-black complex, which is used in chemical tests to detect the presence of starch in various substances.
What are immunoassay tests?
chemical tests used to detect or quantify a specific substance, the analyte, in a blood or body fluid sample, using an immunological reaction
What are two confirmatory tests for the presence of intact explosives located in debris?
Two common confirmatory tests for intact explosives located in debris are gas chromatography-mass spectrometry (GC-MS) and ion mobility spectrometry (IMS). These tests analyze the chemical composition of the debris to identify specific explosives compounds, providing conclusive evidence of their presence.
Is the starch Ewer just determine starch or starch and other carbohyrate?
The iodine test using a starch ewer is mainly used to detect the presence of starch. It specifically tests for the presence of starch molecules by forming a blue-black color in the presence of starch. It does not differentiate between starch and other carbohydrates.
How is osteopetrosis diagnosed?
Osteopetrosis is usually diagnosed when x rays reveal abnormalities or increases in bone density. Bone biopsy can confirm the presence of osteopetrosis, but additional tests may be needed to distinguish one type of the disorder from another.
