Permeability or permeation chromatography.
It is conceptually the simplest.
They appear under a different name "gel filtration", "molecular sieving chromatography" or "size

PEPTIDES AND PROTEINS
The peptide bond that joins amino acids to form peptides and proteins, is chemically an amide type,
formed by condensation between the carboxyl group and amino another with release of a molecule.
Thereby forming a dipeptide.
Cardiolipins also called because they were first found in the heart muscle. This is due to the large
number of mitochondria that are there, and this lipid is located in the inner membrane of these
organelles, in addition to the bacte
Proteins are polyelectrolytes and their net charge depends on its content in a series of amino acids:
glutamic acid; aspartic acid, lysine, arginine and histidine (amino acids are charged side chain).
Depending on the pH the prote
Secondary structure (3D) polynucleotides
Most of the DNA strands are double-stranded except for some viruses. These two chains run antiparallel:
Among them are the pairs joined by hydrogen bonding so that always a purine are coupled with
Reactions to Identify monosaccharides
In alkaline medium, monosaccharides undergo two reactions:
Interconversion aldose - ketose (epimerization)
Dehydration OCCURS by action of acids and Also in a strong acid medium. From the OH They are
Proteins are macromolecules, generally quite large (5000 aa. Small), with a complex three-dimensional
structure whose determination is a difficult task. There are methods such as X-ray crystallography, and

DEFINITION AND CLASSIFICATION OF OPTICAL METHODS OF ANALYSIS.
Optical methods of analysis are the most used, especially ultraviolet microscopy.
They are defined as optical methods of analysis to t
