When treated with ninhydrin, the supplement gives a purple color, while treatment with biuret results in a blue color. The Xanthoprotein test results in a dark orange/red color. What is the possible identity of the supplement? Explain your answer. 2m

That was all that was given to us for this question. I think she is asking about proteins/amino acids present given the color change. she is not very clear.

Answer 1

Nutritional supliments which are nothing but dietary suppliments which are totally depend upon your healthy diet. The suppliments which are used for hair loss that shoul contains Vitamin A, Vitamin B7 and other protiens. Biotin is used for breakdown of proteins to amino acids which give streinth to our hairs. The essential proteins for prevention of hair loss are Keratin, Collagen etc. but in nutritional suppliments for hair loss which have been not contains the above said protiens directly. thats why the test which have been said in the questions have been shown negative results. Biuret and Xanthoprotien test are negative for protiens but ninhydrin test is positive for amino acids. I think and As concern to the suppliments used for hair loss ( Vitamin suppliments for hair loss ) the above said test are not essential.
