Lab 2: Protiens and Starches Purpose: An introduction to testing procedures for two large‚ organic molecules: proteins and starches. Hypothesis: In the test for protiens the water‚ being that it is inorganic will not test positive for protiens; it will serve as the negative control. The milk and 50% egg solution should test positive for protien as they are subsatnce derived from animals which contain protiens in order to carry the functions of life. The sucrose will test negative due

A molecule that contains three fatty acids attached at the oxygen atoms of glycerol. What are the differences between saturated and unsaturated fats? Drawn an example of each. If all bonds are single‚ the fatty acid molecule is saturated. If there is a double bond among the carbon atoms‚ the fatty acid molecule is unsaturated. What form does each of these fats take at

1. Compare the hash values calculated for example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. They change to keep authentication and integrity. 2. Why are the MD5sum and SHA1sum hash values the same every time you calculate for the “example.txt” sample fi le? What if they were different when you re-calculated the hash value at the other end? These are the same to verify authentication and integrity.
