1 You are planning to carry out the Sudan Red test on a set

1. You are planning to carry out the Sudan Red test on a set of 50 samples, but the bottle of Sudan Red dye is several years old. Without wasting a lot of time and effort, how can you be sure that the reagent is still reliable?

2. (A) What is the relationship between albumin and glycine, between starch and glucose, and between triacylglycerols and glycerol? (B) Write a single sentence to express a general rule that explains why the two substance in each pair behave differently in the assays.

3. Several of the substances in lab are everyday kitchen items. Would it have been useful to include soy sauce as one of the unknown substances for the assays?

4. You are given an unlabeled sample of goat milk and an unlabeled sample of soy milk. Which one of the assays that you performed in lab should you use to identify which sample is which? What should you use as a negative control and as a positive control for the assay?

Solution

Suan red if gives positive test with known lipid and showing red color after mixing with lipid then this chemical is consider good

Starch is the polymer of glucose., albumin and glycine both are amino acid both comes out to be protein

Different group present leads to different chemical reaction

No one cannot use soya sauce in such place
