Protein secondary structure Secondary structure refers to highly regular local sub-structures on the actual polypeptide backbone chain. Some parts of the protein are ordered but do not form any regular structures. They should not be confused with random coilan unfolded polypeptide chain lacking any fixed three-dimensional structure.

Experiment 1 – Determination of Density. The densest object was the metal cylinder whose density was g/cm3 and was most likely made of iron whose density is g/cm3 and appeared to be rusting. The objective of the density determination lab was to resolve the density of 6 objects given to us.
