An organic molecule containing a carboxyl group and an amino group; serves as the monomer of proteins.
The covalent bond between the carboxyl group on one amino acid and the amino group on another, formed by a dehydration reaction.
A combination of two amino acids united by means of a peptide bond.
A polymer (chain) of many amino acids linked together by peptide bonds.
chemical side bonds that are formed when the sulfur atoms in two adjacent protein chains are joined together.
More 3-dimensional in shape and are mostly water soluble
a protein containing iron, found in red blood cells, which carries oxygen
A protein fiber with a unique triple-helix that gives it great strength. Tissues with a lot of collagen fibers are typically very strong, e.g. bone, tendons, ligaments, etc.
A process in which a protein unravels, losing its specific structure and hence function; can be caused by changes in pH or salt concentration or by high temperature.
An enzyme that digests proteins by hydrolysis.
A spiral shape constituting one form of the secondary structure of proteins, arising from a specific hydrogen-bonding structure.
Irregular contortions of a protein molecule due to interactions of side chains involved in hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges.
