The cyanide-nitroprusside test can be used to detect sulphur. The test detects sulphhydryl group compounds and is used to test urine in screening tests for the metabolic diseases, cystinuria and homocystinuria.

Why does Biurets reagent react with proteins but not amino acids?
Biuret test works for any compound containing two or more of these groups: CO-NH, CO-NH2, CH2-NH2, CNH-NH2, CS-NH2. Amino acids only have one.
In the metabolism of amino acids for energy what is the fate of the amino group?
Excreted as urea. this was the answer for my test
What is the fate of amino group in the metabolism of amino acids for energy?

Can you distinguish proteins and other amino compounds by the ninhyndrin test?
Because proteins are polymers of amino acids, hydrolysis followed by amino acids determination is a method. Ninhydrin is an oxidating agent which leads to the oxidative deamination of alpha-amino groups. Ninhyndrin test is used to detect ammonia, primary (deep blue or purple color (Ruhemann's purple)) and secondary amines (yellow), this is a proof of free amino acids in proteins. to distinguisn between Amino Acids and proteins you need a peptide bond test which can be done by Biuret test.
What is the reduced sulfur test?
test for amino acids that contain the reduced sulfur group. (:
What amino acids are found in nitroprusside test?
cystine,cysteine,methionin
Do branch chain amino acids show up on a drug test?
no
What amino acids give positive Ehrlich test?
The Ehrlich test is used to determine indoles.
Will amino energy give me a positive reading on drug test?
No. Amino acids are the building blocks of protein; if they'd make you fail a drug test everyone would fail every drug test they take because not only do you eat protein, your body makes many amino acids on its own.
All living cells would test positive for amino acids?
TRUE
Will superpump 250 give a positive drug test?
NO its just caffein and amino acids.
Will Alanine give a negative Biuret test?
Because solutions with "free" amino acids don't have peptide bonds and peptide bonds need to be present in order for the test to be positive.
