This document appears to be notes from a protein analysis practical lab completed by Dimitrije Spasic. It includes results and observations from 16 different exercises, such as measuring hydrophobic and hydrophilic residues in exercise 1, observing an angle of 35.31 degrees between two helixes in exercise 3, noting anti-parallel sheets in exercise 4, and identifying specific amino acid residues and structural elements like helices, loops, and phosphates in other exercises.
