Structural Roles

Structural Role of Biomolecules

The structural role of biomolecules is the function or job of carbohydrates lipids and proteins in making various parts or an organism

Structural Carbohydrates

Carbohydrates in the form of polysaccharides provide strength shape and rigidity to the cells and bodies of plants fungi and animals

Examples of structural carbohydrate

Cellulose chitin and lingin

Cellulose

The structural carbohydrate found in the cell walls of plants

Chitin

The structural carbohydrate found in the cell walls of fungi and also in the exoskeleton of insects

Ligin

The structural carbohydrate in plants with wood or bark

Structural Proteins (Body)

Keratin myosin elastin and lipoprotein

Structural Lipids

A type of lipid that forms and maintains biological membranes and protective barriers in living cells

Examples of structural lipids

Phospholipids and myelin

Phospholipids

A major component in cell membrane, fatty acids compose the hydrophobic tail of the phospholipid bilayer

Myelin

A fatty white substance that surrounds the axons of mother neurons and help insulate electrical impulses
