A polymer (chain) of many amino acids linked together by peptide bonds.
- Primary structure
- The level of protein structure referring to the specific sequence of amino acids.
A three-dimensional biological polymer constructed from a set of 20 different monomers called amino acids.
The particular shape of a complex, aggregate protein, defined by the characteristic three-dimensional arrangement of its constituent subunits, each a polypeptide.
The localized, repetitive coiling or folding of the polypeptide backbone of a protein due to hydrogen bond formation between peptide linkages.
The reactant on which an enzyme works.
Irregular contortions of a protein molecule due to interactions of side chains involved in hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges.
A molecule that has both a hydrophilic region and a hydrophobic region.
A sugar (monosaccharide) or one of its dimers (disaccharides) or polymers (polysaccharides).
A lipid bilayer, containing proteins, that surrounds cells and keeps the cellular contents together. May have additional roles in regulating the flow of materials in and out of the cell, communicating information and carrying out specific biochemical functions.
