A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

//&#;&#;Protein is an important nutrient for supporting body functions like tissue repair, cell maintenance, hormone function, enzymatic reactions, and muscle building. Protein also helps regulate blood sugar and keeps you feeling full, which is why it's important for weight management.

//&#;&#;Proteins are often called the bodys building blocks. They are used to build and repair tissues. They help you fight infection. Your body uses extra protein for energy. The protein foods group includes seafood, lean meat and poultry, eggs, beans and peas, soy products, and unsalted nuts and seeds. Protein is also found in the dairy group.

//&#;&#;Protein is the major building block of the human body. It builds and maintains tissue. During periods of growth, such as infancy, childhood, and pregnancy, the body needs more protein.

//&#;&#;Protein is a part of every cell in the body. It helps the body to build and repair cells and tissues. Protein is a major component of the skin, muscle, bone, organs, hair, and nails.

Protein consists of carbon, hydrogen, oxygen, and nitrogen. The addition of nitrogen gives protein its unique distinction from carbohydrate and fat, along with establishing the signature name, amino acid.Much like simple sugars, which link together to form a complex carbohydrate (see What Is a Carbohydrate?), amino acids are the building blocks for the more complicated protein molecule.

//&#;&#;Whey protein is a high quality protein from dairy foods that can help build muscle mass. It may also aid weight loss. If youd like to try whey protein supplements, a large variety is available ...

//&#;&#;A protein is a basic structure that is found in all of life. Its a molecule. And the key thing about a protein is its made up of smaller components, called amino acids.

//&#;&#;Learn more. Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the bodys tissues and organs. Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long ...

Protein is also a critical part of the processes that fuel your energy and carry oxygen throughout your body in your blood. It also helps make antibodies that fight off infections and illnesses ...

English Language Learners Definition of protein. : a substance found in foods (such as meat, milk, eggs, and beans) that is an important part of the human diet. See the full definition for protein in the English Language Learners Dictionary.

//&#;&#;Protein plays a vital role in regulating the concentrations of acids and bases in your blood and other bodily fluids (, ).The balance between acids and bases is measured using the pH scale.

Structural Proteins. These can be found in the fibers of both smooth muscles and skeletal muscles, as well as in cardiac muscle around the heart. Collagen, for example, is the most abundant protein in human and animal bodies.Some structural proteins also have contractile functions, which aid in the movement of muscles.

Proteins play countless roles throughout the biological world, from catalyzing chemical reactions to building the structures of all living things. Despite this wide range of functions all proteins are made out of the same twenty amino acids, but combined in different ways. The way these twenty amino acids are arranged dictates the folding of the protein into its primary, secondary, tertiary ...

//&#;&#;Protein is essential in lowering blood pressure, preventing diabetes and more. Check out some of the best, nontraditional sources of protein to add to your diet!

Protein. We need to eat protein foods such as lean meat, poultry, fish, eggs, tofu, nuts, seeds and legumes/beans every day. Protein is essential for building, maintaining, and repairing the tissues in our body. As well as providing us with protein, these foods contain other essential nutrients.

//&#;&#;Protein powders are powdered forms of protein that come from plants (soybeans, peas, rice, potatoes, or hemp), eggs, or milk (casein or whey protein). The powders may include other ingredients such as added sugars, artificial flavoring, thickeners, vitamins, and minerals. The amount of protein per scoop can vary from to grams.

During protein synthesis, the carboxyl group of the amino acid at the end of the growing polypeptide chain chain reacts with the amino group of an incoming amino acid, releasing a molecule of water. The resulting bond between amino acids is a peptide bond. Peptide bond formation between two amino acids. In a peptide bond, the carbonyl C of one ...

//&#;&#;A weight-based recommended daily allowance (RDA) of grams per kilogram of body weight. For a -pound person, that comes to grams of protein each day. (You can convert your body weight from pounds to kilograms by dividing by ; so,

//&#;&#;No doubt about it, protein is good for you -- and can even help you shed those unwanted pounds. But (and you knew there was a "but," right?), it's important to eat the right amount and the right ...

Protein binding can enhance or detract from a drug's performance. As a general rule, agents that are minimally protein bound penetrate tissue better than those that are highly bound, but they are excreted much faster. Among drugs that are less than percent protein bound, differences appear to

//&#;&#;Proteins with quaternary structure may consist of more than one of the same type of protein subunit. They may also be composed of different subunits. Hemoglobin is an example of a protein with quaternary structure. Hemoglobin, found in the blood, is an

Protein is a nutrient your body needs to grow and repair cells and to work properly. Protein is found in a wide range of food and its important that you get enough protein in your diet every day. How much protein you need from your diet varies depending on your weight, gender, age and health.

Protein is key to good health -- it's involved in immune function, oxygen transport and maintaining strong muscle tissue. "Crude protein" is a measure of how much protein is in food, based on laboratory tests studying the food's chemical composition.

//&#;&#;Protein energy malnutrition (PEM) describes a range of disorders occurring mainly in developing countries. It mainly affects young children and is the result of both too little energy and too little protein in the diet. The two most common forms of PEM are Marasmus and Kwashiorkor.
