Types of Protein and Their Uses
Proteins come in a variety of types, according to function.
Proteins recognize and bind themselves to foreign substances to make it neutralize them and help protect the body.
An example is of an antibody is immunoglobulin G (IgG).

An enzyme increases the speed at which a chemical reaction happens.
An example of an enzyme isphenylalanine hydroxylase.
This enzyme catalyzes the breakdown of the amino acid phenylalanine.
Infants born unable to make this enzyme have toxic effects from the incomplete metabolism of phenylalanine.
Messenger
Also known as signaling proteins, they allow communication between cells.
They include some types of hormones.
These proteins transmit signals to coordinate biological processes between cells, tissues, and organs.
An example of a messenger protein is somatotropin, also known as growth hormone.
Structural
Structural proteins allow cells to maintain their shape and organization.
An example of a structural protein is actin.
An example isferritin, which stores iron for use by blood cells and other body tissues.
How Much You Need
You likely wont have problems getting enough protein.
Getting your protein from diverse sources, including ones that are plant-based, will give you the healthiest balance.
Protein Deficiency
Protein deficiencies are rare for people in wealthier countries, such as the United States.
However, permanent physical and mental impairments can take place if treatment is delayed.
If treatment comes too late, shock, coma, and death can result.
