How Many Types Of Proteins Are In The Human Body – Protein is an important nutrient that your body uses around the clock. It helps build and repair muscles, tissues, bones and organs and helps neurons in your brain communicate with each other. It’s also a must if you’re trying to build muscle or gain strength.
To effectively use this nutrient in your diet, it’s important to understand the two different types of protein—namely, complete and incomplete. Protein is made of building blocks called amino acids, and if it contains all nine essential amino acids that your body can’t make on its own, it’s called a complete protein.

How Many Types Of Proteins Are In The Human Body
In this guide, we’ll explore the different types of protein, the best sources of protein, and tips to help you meet your daily protein needs.
Four Types Of Protein Structure
The three macronutrients your body needs to survive are carbohydrates (carbohydrates), fats, and proteins. Protein is in every cell in your body and is needed to support critical functions. For example, it helps your immune system, brain function, vision and pH balance – it also provides what is needed to produce enzymes, antibodies and hemoglobin.
Protein is also important for muscle growth and recovery, and the more you exercise, the more protein you need. As such, protein intake is a popular topic of discussion among bodybuilders and athletes.
Each gram of protein contains four calories, and the daily amount you need depends on your activity level, age, height, weight, and health. On average, most people need 0.8 grams of protein per kilogram of body weight each day. And if you exercise regularly, you may need 1.2 to 2 grams of protein per kilogram of body weight each day.
Protein is made up of building blocks called amino acids. When you consume protein, your body breaks it back down into amino acids, which it can then use and recombine when needed. All amino acids are necessary for health and well-being, but the body cannot produce nine of them. These are called essential amino acids and include:
What Is A Protein?
To get these essential amino acids, you need to consume food sources that contain them as part of the protein content. Three essential amino acids are known as branched-chain amino acids, or BCAAs, which help prevent muscle loss, boost your energy levels, improve performance, and speed recovery after exercise. They can help you reach your fitness goals and are usually taken as a pre-workout supplement.
These essential amino acids are essential for your health and your body can produce them by recombining other amino acids.
If you eat enough protein but don’t consume complete proteins, your body isn’t getting everything it needs to function. Here’s a quick comparison of complete and incomplete protein.
Complete proteins contain significant amounts of all nine essential amino acids. They are most commonly found in animal products, but some plant proteins also contain complete protein.

You can also combine incomplete plant proteins to get a complete protein in your diet. For example, rice and beans are individually incomplete proteins, but together they form a complete protein. It’s the same with barley and lentils.
In addition to complete and incomplete proteins, or even plant and animal proteins, different types of animal protein foods contain different types of proteins. You can find them in supplements to better target and include different types of protein in your diet.
There are other protein supplements (such as collagen and BCAA supplements), but not all of them contain complete protein. Above all, using high-quality protein supplements with an emphasis on bioavailability is a must – bioavailability refers to your body’s ability to absorb nutrients. Low bioavailability can result in the loss of protein that your body cannot absorb.
Incomplete proteins lack one or more essential amino acids. You can check which amino acids a food contains by looking it up in the USDA Nutrient Database and looking at the amount per serving. In general, a food containing less than 0.1 grams of a specific essential amino acid per serving is considered incomplete.

However, as we noted earlier, you can combine incomplete proteins to make complete proteins. For example, grains combined with beans or legumes are a common way to get complete protein in a meal. While there is nothing wrong with eating different types of protein, including incomplete proteins from plant sources, you need sources of complete proteins for a healthy diet.
Depending on your activity level and muscle growth goals, some people will find it difficult to meet their daily protein needs – especially if you’re following a high-protein diet. Here are some tips to help you meet your daily protein needs:
Understanding the different types of protein can help you support your body and reach your muscle building goals. Supplements are the easiest way to fill in the gaps in your protein intake, giving you the ability to add measured amounts of this important nutrient to each (or every) meal. Consider the following supplements to get you started:
Remember: Using quality supplements is the best way to ensure your body is getting the amount of protein listed on the label. Low-quality supplements can be difficult for your body to absorb, allowing some (or most) of the protein to pass through your system.

What Is A Protein? A Biologist Explains
Editor’s note: Nathan Ahlgren is an associate professor of biology at Clark University. In this interview, he explains exactly what proteins are, how they are made, and how many different functions they perform in the human body.
Protein is a basic structure found in all life. It is a molecule. And the main thing about protein is that it is made up of smaller components called amino acids. I like to think of them as different colored beads. Each bead would represent an amino acid, which are smaller molecules containing carbon, oxygen, hydrogen and sometimes sulfur atoms. So a protein is essentially a sequence of these small individual amino acids. There are 22 different amino acids that you can combine in any number of different ways.
A protein does not normally exist as a string, but actually folds into a certain shape depending on the sequence and how these different amino acids interact with each other. This shape affects what the protein does in our body.
The amino acids in our bodies come from the food we eat. We also make them in our bodies. For example, other animals produce proteins and we eat them. Our bodies take this chain and break it down into individual amino acids. Then it can convert them into whatever protein we need.

Once proteins are broken down into amino acids in the digestive system, they are taken into our cells and float around the cell like these little individual beads in our analogy. And then inside the cell, your body basically joins them together to make the proteins that your body needs to make.
We can make about half of the amino acids we need ourselves, but we have to get the rest from food.
Scientists aren’t exactly sure, but most agree that there are about 20,000 different proteins in our bodies. Some studies suggest there may be even more. They perform a variety of functions, from some metabolic conversions to holding cells together to making muscles work.
Their functions fall into several broad categories. One is structural. Your body is made up of many different structures – think string-like structures, globules, anchors, etc. They make up the stuff that holds your body together. Collagen is the protein that gives structure to your skin, bones, and even teeth. An integrin is a protein that makes flexible connections between your cells. Your hair and nails are made of a protein called keratin.
Levels Of Protein Structure
Another big role they play is biochemistry – how your body carries out certain reactions in your cell, such as breaking down fats or amino acids. Remember when I said that our bodies break down the protein we get from food? Even this function is performed by proteins such as pepsin. Another example is hemoglobin, the protein that carries oxygen in your blood. So they carry out these special chemical reactions inside you.
Proteins can also process signals and information, such as the circadian clock proteins that keep time in our cells, but these are some of the main categories of functions that proteins perform in the cell.
Different types of food have different protein content. Plants such as wheat and rice are high in carbohydrates but low in protein. But meat generally has more protein content. Your body needs a lot of protein to build muscle. This is why protein is often associated with eating meat and building muscle, but protein is actually associated with much, much more.
