Protein Structure and Function

Proteins are polymers of amino acids arranged in a linear sequence.
They are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules.
Functions include structural, regulatory, contractile, protective, transport, storage, membrane-related, toxic, and enzymatic roles.
Each cell in a living system may contain thousands of proteins, each with a unique function. Their structures, like their functions, vary greatly.
Protein structures and molecular weights vary, critical to its function, and this shape is maintained by many different types of chemical bonds.
Some proteins are globular in shape, while others are fibrous in nature.
Exposure to chemicals, changes in temperature, and pH may lead to permanent changes in the shape of the protein, causing denaturation.
Proteins are marginally stable, achieving stability within narrow ranges of temperature and solvent conditions.
Protein structure is dictated by the amino acid sequence.
All proteins are made up of different arrangements of the 20 alpha amino acids.
Every cell has many proteins, each with unique roles.
Protein shapes can be globular or fibrous.
Denaturation can occur with chemical exposure, temperature or pH changes, causing permanent shape alterations.
Protein stability is sensitive to temperature and solvent conditions.
Protein structure directly correlates with their amino acid sequence.
Proteins are made of a variety of amino acid arrangements.
