The
basic structural components of cells
and tissues and of the enzymes
controlling biochemical reactions.
Proteins are complex macromolecules made up of long chains of
subunits called amino acids.
These chains fold into complex three-dimensional shapes. Protein modeling
using methods like homology modeling and molecular dynamics is a central technology in drug discovery, usually aiming to identify targets for potential drugs.
Living
cells contain many molecules
that consist of amino acidpolymers folded to form more-or-less definite
three-dimensional structures; these are termed proteins. Short polymers lacking definite three-dimensional
structures are termed peptides.
Many proteins incorporate structures other than amino acids, either as covalently attached side chains or as
bound ligands.
Molecular
objects made of protein form much of the molecular
machinery of living cells.
The
chemical building blocks from which mammalian cells,
organs, and tissues like muscle are made. Proteins also serve double-duty as
hormones, enzymes
and antibodies, which help fight off invading germs. Proteins are made of
long chains of even smaller building blocks called amino acids. Amino acids
determine the size, shape, and length of protein molecules.
They also give protein molecules
the odd ability to coil and uncoil like tiny, cellular snakes.
