LOUS Foro Base Biological Chemistry Chm-094 LL Post-lab questions 1. (7 points) List the numbers of all experiments in which you have demonstranted this a) albumin can be denatured by ionic salts: b) albumin can be denatured by an organic compound that is capable of forming its own hydrogen bonds with side chains of amino acids, thus disrupting hydrogen bonds within a protein c) albumin can be denatured by an acid: d) albumin can be denatured by a base: e) albumin can be denatured by heating f) albumin can be denatured by a surfactant g) denatured catalase cannot function properly 2. (2 points) a) What observation lead you to the conclusion that ovalbumin got denatured after being mixed with rubbing alcohol? b) What observation lead you to the conclusion that catalase got denatured after being heated? Note that in both questions you are asked what you have observed. Please do not write "breaking of hydrogen bonds". While it is a correct statement, it is not a correct answer - it is not possible to observe breaking of bonds with a naked eye. 3.
