Study the chemistry behind biological macromolecules, techniques in biochemistry and their relevance to human health. GC is used as one test to help identify components of a liquid mixture and determine their relative concentration. if the molecule is a substrate for the enzyme, it will bind tightly to the enzyme and the unbound analytes will pass through in the mobile phase, and elute out of the column, leaving the substrate bound to the enzyme, which can then be detached from the stationary phase and eluted out of the column with an appropriate solvent. However, how -syn drives the pathology of PD remains elusive. Question 4: Which technique would you use to separate proteins by charge? In this in vitro study, the rates of disappearance of monomeric alpha-synuclein and appearance of fibrillar alpha-synuclein were compared for the wild-type (WT) and two mutant proteins, as well as equimolar mixtures that may model the heterozygous PD patients.
