Types of proteins

defense proteins

Defense proteins help organisms fight infection, heal damaged tissue, and evade predators.

9 different types of proteins

Enzymes, structural, signaling, regulatory, transport, sensory, motor, defense, and storage

Protein

Large molecules composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein. Proteins are required for the structure, function, and regulation of the body's cells, tissues, and organs.

motor proteins

Motor proteins keep cells moving and changing shape. They also transport components around inside cells.

regulatory proteins

Regulatory proteins bind DNA to turn genes on and off. Active genes are used to build proteins.

sensory proteins

Sensory proteins help us learn about our environment. They help us detect light, sound, touch, smell, taste, pain, and heat. Some organisms can even detect electricity or magnetism.

signaling proteins

Signaling proteins allow cells to communicate with each other. Signals, receptors, and relay proteins work together to get information from the outside of a cell to the inside.

storage proteins

Storage proteins store nutrients and energy-rich molecules for later use.

Enzyme

They build and break down molecules. They are critical for growth, digestion, and many other processes in the cell.Without them, chemical reactions would happen too slowly to sustain life.DNA polymerase builds DNA molecules. It reads the old DNA

transport proteins

Transport proteins move molecules and nutrients around the body and in and out of cells.

Hemoglobin

hemoglobin is a transport protein and its specific function is to transport oxygen.

structural proteins

structural proteins strengthen cells, tissues, organs, and more. Nature can build materials that are very strong.
