Protein is the basic component of living cells and is made of carbon, hydrogen, oxygen, nitrogen and one or more chains of amino acids. The three types of proteins are fibrous, globular, and membrane.
Fibrous proteins form muscle fiber, tendons, connective tissue and bone.
Examples of fibrous proteins are:
Globular proteins are more water soluble than the other classes of proteins and they have several functions including transporting, catalyzing, and regulating.
Here are examples of globular proteins:
Membrane proteins play several roles including relaying signals within cells, allowing cells to interact, and transporting molecules.
Examples of membrane proteins include:
Here are examples of foods high in protein with the number of grams per 100 grams of the food:
So, now you have seen a lot of different examples of proteins in different foods and substances.
