You have to be more specific. We will not do the entire lab for you. Here are some hints, though, if you are totally lost:

C=carbon   H=hydrogen     O= oxygen  The first part of your lab is simply counting up the number of times each of these elements appears in the molecule they ask about; this is true when you are asked to give the formula for the compounds, as well. Just add up the number of each type of molecule, and write it as a subscript (that is, the number is slightly below the line the letters are written on.) When it asks if there is a carboxyl group, it shows you what a carboxyl group is; is there one in each of the fatty acids?

You can do this. If you have specific questions, we are happy to help, but we will never just do the lab for you.  Good luck!

As already stated, you have to be more specific.  Just where are you having difficulty?  It is not fair to ask a tutor to answer the whole question for you, when you have not given any response.  It is important to know the constituent elements of both proteins and fats.  Fats are primarily composed of carbon, hydrogen and oxygen, occasionally with other elements.  Proteins are composed of amino acids, of which there are about 26 coded by the DNA of the cell.  Amino acids are unique, they do not provide high energy like fats, but they are the molecules that make up proteins.  These are much more important than fats, which largely only store energy.  Proteins are the "building blocks" of the body, and are necessary for muscle as well as enzymes.  Hope this helps....
