best known as enzymes

Catalytic Protein

participates in most metabolic reactions that occur in cells.


also called immunoglobulins or antibodies

Defense Proteins

bind to small biomolecules and transport then to other locations in the body.

Transport Proteins

most well known transport protein


Transport protein carries iron from the liver to the bone marrow


carriers of cholesterol in the bloodstream

High and low density lipoproteins

transmit signals to coordinate biochemical processes between different cells, tissues, and organs.

Messenger Proteins

necessary for all forms of movement.

Contractile Proteins

confer stiffness and rigidity to otherwise fluid-like biochemical systems.

Structural Proteins

helps control the movement of small molecules and ions through the cell membrane

Transmembrane Proteins

proteins bind small molecules for future use.

Storage Proteins

they acts as sites which messenger molecules can bind and thereby initiate the effect that messenger "carries"

Regulatory Proteins

Important in the early stages of life.

Nutrient Proteins

proteins that are part of the system by which the acid-base balance within body fluids is maintained.

Buffer Proteins

helps maintain fluid balance between blood and surrounding tissue.

Fluid-balance Proteins

contains carbohydrates or carbohydrate derivatives in addition to amino acids.


fibrous protein

- structure involves the presence of nonstandard amino acids 4-hydroxyproline and 5-hydroxylysine derivatives


a glycoprotein produced by an organism as a protective response to the invasion of microorganisms or foreign molecules.

- serve as antibodies to combat the invasion of antigens


foreign substance such as bacterium or virus, that invaded the human body.


biochemical molecule that counteracts a specific antigen.


conjugated protein that contains lipids in addition to amino acids.


a lipoprotein that is involved in the transport system for lipids in the bloodstream

Plasma lipoproteins

transports dietary triglycerols from the intestine to the liver and to the adipose tissue.


transports triglycerols synthesized in the liver to adipose tissue.

Very-low density lipoproteins

collects excess cholesterol from the body tissues and transports it back to the liver for degradation.

High-density lipoproteins
