Did you know that the human body, minus water, is 75% protein?
It is.
Our bodies are made up primarily of protein and knowing that little fact helps a person understand why they need to make sure they are getting the suggested amounts of protein daily in their diets. If not, then making sure they are taking protein supplements to reach those required amounts.
Our bodies NEED protein not only to function and stay healthy, but to stay alive. The Amino acids found in protein are vital in every human bodily function. Protein is crucial in formatting bones, teeth, and tissues.
There are three different types of protein Globular, Fibrous and Membrane.
The average person, when hearing those three terms, my find themselves thinking they know nothing about protein. However when you use the more common terms, people are surprised by how much they really do know.
Take for example the term Fibrous Protein. This type of protein is found only in animals. Why? Because Fibrous protein is Collagen – the key component in connective tissue growth—and Keratin—the protein that is found in hair and finger nails.
Globular proteins are typically made up of enzymes and unlike fibrous proteins, globular proteins can act as messengers. It transmits messages to regulate the biological processes. This function is done by hormones, like insulin. One of the most well-know globular proteins is hemoglobin which is the iron containing oxygen transportation system to red-blood cells.
Hemoglobin is found in the blood and carries oxygen from the respiratory organs to the rest of the body (i.e., the tissues). It then releases the oxygen to burn nutrients to provide energy to power the functions of the organism. Then it collects the resultant carbon dioxide to bring it back to the respiratory organs to be dispensed from the body. In mammals, this kind of protein makes up 97% of the red blood cells’ dry content, and around 35% of the total content (including water).
Membrane proteins serve as the receptors and provide transit channels for the protein to pass in and through to the cell membranes. More than half of all proteins interact with membranes.
Understanding the roles that these three types of proteins play within our bodies helps us to make sure we are supplying our body with the healthy types of protein in the correct amounts. Look for more posts later on all the various types of proteins you can eat, and supplements you can take, to help your body get the nourishment it needs.
