A complete or whole protein is one in which all nine essential amino acids are present and for which a protein rating of 20 is achievable. There are twenty amino acids that are the building blocks of protein in humans and animals. Nine of these amino acids cannot be produced by your body and must be obtained through food or supplements. So they are called essential or indispensable.
Based on Protein Efficiency Ratios, meat, dairy, and soy each contain these nine essential amino acids in the proportions to meet the 100% WHO/ FAO/ UHN requirements
Apart from soy, no single digestible plant material contains the nine essential amino acids in sufficient proportions to be considered complete.
PROFI Pro™ Protein Booster (Original) is a blend of plant proteins that has been designed to meet 100% amino acid requirement for humans aged 3 and up. The essential amino acids lysine, methionine, cysteine, threonine and tryptophan are of particular concern because they are often lacking in plant based diets. PROFI Pro Inc. has taken special care to ensure that these amino acids, in particular, are at the required levels to meet the definition of complete protein.
Here is a list of all 9 essential amino acids and a description of their special functions in the human body.
1. Histidine – Histidine is utilized by your body to develop and maintain healthy tissues. It is a component of glycoprotein that plays numerous roles in the body including immunity and the formation of new blood vessels. Adequate histidine levels are essential to good mental and physical health.
2. Isoleucine – Isoleucine is widely recognized as an amino acid that can increase endurance and help to heal muscle tissue. It is particularly recommended to professional athletes and body builders, to boost energy levels and to assist the body in recovering from strenuous physical activity6.
3. Leucine – Leucine helps in regulating the blood-sugar levels7, and promotes the growth and the recovery of muscle tissue. This amino acid is also known for preventing the breakdown of muscle proteins caused by injury or stress. Leucine is important not just for muscle building, but for weight loss as well.
4. Lysine – Lysine is vital for proper growth and plays an important role in the production of carnitine, which is a nutrient that transforms fatty acids into energy and lowers cholesterol levels. In addition, this amino acid helps the body to absorb calcium, while playing an essential role in the formation of collagen – a substance necessary for both bones and connective tissues like skin, cartilage, and tendon.
5. Methionine – Methionine is a supplier of sulfur and other compounds that our body needs for normal metabolism and growth. Sulfur is an important component of many cellular molecules and critical to cell metabolism. Methionine and cysteine are used to produce glutathione, and glutathione is important in the regulation of cell division, growth and DNA repair. If you lack adequate sulfur, your body will be less able to perform some antioxidant functions that are mitigated by glutathione.
6. Phenylalanine – According to research, this amino acid can help treat chronic pain, and to strengthen the effect of UVA radiation for people with vitiligo, a condition in which the skin loses pigmentation. Phenylalanine is considered to be helpful in treating depression, because this amino acid stimulates the production of brain chemicals like dopamine.
7. Tryptophan – Tryptophan is known for relieving minor PMS, for enhancing relaxation and sleep, for soothing nerves and anxiety, and for reducing carbohydrate cravings. Tryptophan is also vital for the production of serotonin, which is a brain chemical involved in regulating mood. When you suffer from depression, this may be due to a decreased amount of serotonin released from the nerve cells into your brain. Therefore, tryptophan can have an antidepressant function by increasing the concentration of serotonin in your blood.
8. Valine – Valine is important for the regulation of the immune system. It is also proven to help alleviate disorders of the muscles, such as muscle wasting. Probably the greatest benefits of valine are experienced by athletes performing long-distance sports and body-building, because this amino acid is important for the muscle tissue recovery and for the muscle metabolism, while increasing exercise endurance.
9. Threonine – Threonine is vital for your health. This amino acid supports central nervous26, cardiovascular, liver, and immune system functioning In addition, threonine aids in building strong bones30.
As you can see, each amino acid has its own special functions in the human body. However, perhaps the most important value of amino acids is how they work together as proteins to perform a myriad of functions that are vital to the growth, regulation and maintenance of tissues.
