If you want to improve your health and fitness – protein can help!* Protein provides the body with the building blocks to produce amino acids that are used for building muscle. While both carbohydrates and fats can vary from diet to diet, protein is one nutrient that should remain constant. The benefits are vast! Protein may help promote:

Next, make sure the grams of protein per serving are adequate for your goal. A good general rule of thumb is to consume 1 gram of protein for every pound of body weight. Be sure to consume your daily allotment in small amounts throughout the day to prevent overconsumption and to maximize your results.

Once you've selected your protein powder, you'll want to make sure you're doing everything right to get the most out of it. To recap, ideally you should be consuming a fast acting protein (whey) immediately before and after your workout, as well as a supplement in between meals. To keep your energy levels up, combine this protein with a good source of complex carbohydrates. Always consult with a qualified healthcare professional prior to beginning any diet or exercise program or taking any dietary supplement.

Athletes and those looking to build muscle might benefit from increased protein intake, but they should be aware of the risks. Excess protein is typically processed by the body, but may cause a strain on the liver and kidneys, and may also increase cancer risk particularly for protein from animal sources.

If there's one nutrient that's an absolute must in your diet, protein is it. Protein forms the building blocks for your muscle tissue, so without it your body would lack a critical component needed for muscle to even exist. Whey is one of the best absorbed forms of protein in the body, even higher than chicken or fish.* Supplement with high quality whey protein to get the results you long for!* The benefits of using a whey protein powder include: Whey protein is easy to mix with water, juice or milk, and will provide about 20-25 grams of protein per serving. Those who make use of whey protein powders within their training schedule often show better results than those who don't so be sure that you're not skipping out on the benefits you could be seeing. There are many different forms and flavor varieties of whey protein, so you're sure to find one that you enjoy.

Today, the most popular ways to make protein are isolating and hydrolyzing whey. Whey can be isolated from milk during the process of making cheese. Or, it can be hydrolyzed by chopping proteins into tiny chunks called peptides. Both methods provide fast digesting protein for your starving muscles.* The main forms of whey protein include:RCSB Protein Data Bank - RCSB PDB

Biochemistry. any of numerous, highly varied organic molecules constituting a large portion of the mass of every life form and necessary in the diet of all animals and other nonphotosynthesizing organisms, composed of 20 or more amino acids linked in a genetically controlled linear sequence into one or more long polypeptide chains, the final shape and other properties of each protein being determined by the side chains of the amino acids and their chemical attachments: proteins include such specialized forms as collagen for supportive tissue, hemoglobin for transport, antibodies for immune defense, and enzymes for metabolism.

Originally a theoretical substance thought to be essential to life, further studies of the substances he was working with overthrew this, but the words protein and proteid continued to be used in international work on the matter and also for other organic compounds; the modern use as a general name for a class of bodies arose in German. The confusion became so great a committee was set up in 1907 to sort out the nomenclature, which it did, giving protein its modern meaning and banishing proteid. Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of chains of alpha-amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary to the functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

Any of a large class of complex organic chemical compounds that are essential for life. Proteins play a central role in biological processes and form the basis of living tissues. They consist of long chains of amino acids connected by peptide bonds and have distinct and varied three-dimensional structures, usually containing alpha helices and beta sheets as well as looping and folded chains. Enzymes, antibodies, and hemoglobin are examples of proteins. 10 angstrom units). Phenylalanine absorbs very little ultraviolet light; tyrosine and tryptophan, however, absorb it strongly and are responsible for the absorption band most proteins exhibit at 280–290 nanometres. This absorption is often used to determine the quantity of protein present in protein samples.

Proteins are sometimes described as long necklaces with differently shaped beads. Each bead is a small amino acid. These amino acids can join together to make thousands of different proteins. Scientists have found many different amino acids in protein, but 22 of them are very important to human health.

Protein from animal sources, such as meat and milk, is called complete, because it contains all nine of the essential amino acids. Most vegetable protein is considered incomplete because it lacks one or more of the essential amino acids. This can be a concern for someone who doesn't eat meat or milk products. But people who eat a vegetarian diet can still get all their essential amino acids by eating a wide variety of protein-rich vegetable foods. You can figure out how much protein you need if you know how much you weigh. Each day, kids need to eat about 0.5 grams of protein for every pound (0.5 kilograms) they weigh. That's a gram for every 2 pounds (1 kilogram) you weigh. Your protein needs will grow as you get bigger, but then they will level off when you reach adult size. Adults, for instance, need about 60 grams per day.

To figure out your protein needs, multiply your weight in pounds times 0.5 or you can just take your weight and divide by 2. For instance, a 70-pound (or 32-kilogram) kid should have about 35 grams of protein every day. If you only know your weight in kilograms, you need about 1 gram of protein each day for every kilogram you weigh.

"Most of the studies show results for up to six months, but after six months they begin to lose effectiveness, either because people do not adhere to this diet very well in the long term, or because they get used to this diet biologically," Hu tells WebMD. "So in the long term the high-protein diets tend to lose their ability to maintain the weight."

Chicken and turkey are excellent sources of lean protein, especially if you have skinless portions. A 4-ounce portion of chicken or turkey is about the size of a deck of cards and provides 35 grams of protein. Once cooked, you can enjoy chicken cold or hot, as part of a salad, on sandwiches, by itself, or in other dishes. It can be helpful to check a list of the protein grams in different parts of the chicken.

241749) are high in protein and can give a boost to vegan or vegetarian diets. Note that the amount needed to supply a protein equivalent is less for nuts and seeds than it is for beans. In addition to protein, most nuts and seeds provide polyunsaturated fats, fiber, minerals (such as magnesium and calcium), and phytonutrients. The amount of protein and carbohydrate in a protein powder varies a fair amount depending on the source of the powder, so you will need to read the label. Protein powder can be made from whey (milk) protein, egg, soy, rice, peas, and other sources. Many types of protein powder are marketed to bodybuilders and athletes. Be sure to check the labels and avoid any unwanted additives. Protagen is developing generic & proprietary tests to enable physicians to accurately diagnose patients who have critical autoimmune diseases, such as RA, SLE, SSc and others, earlier in the disease progression, which will enable earlier treatment and improve long-term outcomes. We are also developing tests to enable patient stratification, prognosis and disease-modified therapy response prediction, all with the goal of improving individualized patient care.

Protagen is currently setting up an international Scientific Advisory Board with Key Opinion Leaders from the immuno-oncology and autoimmune disease fields. These expert panels will support our efforts in engaging with the medical and scientific community to develop products that are aimed at market needs. Autoimmune diseases are inherently complex due to their numerous and frequently overlapping spectrum of symptoms, which can make reaching a conclusive diagnosis, and prescribing the correct medication difficult. Here you can download our whitepaper to see why fighting autoimmune disease requires a more personalized approach. Our current focus for CDx and Dx test development is within systemic and organ-confined autoimmune diseases, a range of indications with unmet diagnostic and therapeutic needs, including Rheumatoid Arthritis, Systemic Lupus Erythematosus, Ankylosing Spondylitis, Systemic Sclerosis, Multiple Sclerosis and Neuromyelitis Optica.
