General characteristics of the macromolecular substances solutions (HMC)

  • Planner

  • General characteristic of HMC. Solubility of HМС.

  • Obtaining HMC methods.

  • Physical and chemical properties of HMC.

  • Stability of HМС.

High molecular compounds (macromolecules)

  • High molecular compounds (macromolecules)

  • are an organic and inorganic substances, that have in their structure molecules of the chain form with a large number of small structurally similar or homogeneous units linked together by covalent bonds.

  • A macromolecule is a very large molecule commonly created by some form of polymerization. In biochemistry, the term is applied to the four conventional biopolymers (nucleic acids, proteins, carbohydrates, and lipids), as well as non-polymeric molecules with large molecular mass such as macrocycles. The constituent molecules from which macromolecules are assembled are called monomers (mono=single, meros=part).

Natural classification of High molecular compounds

Classification HМС according to the macromolecule’s shape

  • Globular

  • (milk proteins, haemoglobin)

Classification macromolecules according to the structure of polymeric chain

Classification HМС according to the chemical nature of atoms

  • Carbonchain Heterochain

Solubility stage of HMC in a low molecular solvent

Gel filtration

Obtaining method of HMC

  • Polymerization:

  • nCH2=CH-CH=CH2 → (-CH2-CH=CH-CH2-)n

Laminar flowing

Newtonian: frictional force proportional to the gradient of velocity flowing and contact area of the layers moving

Protein denaturation
