Chemical Properties

Yellow or orange yellow crystalline powder; odorless and tasteless; case of light easily decomposed.


Ubidecarenone is a small molecule lipid-soluble quinone compounds widely found in plant and animal cells, its structure is similar to the structure of vitamin K, used alone or in combination with vitamin E as a powerful antioxidant. It is required for energy generation (ATP) circulation. It promotes phosphorylation reaction and protect the structural integrity of the biofilm oxidation function. Ubidecarenone of different sources are different with its side chain prenyl units number, Ubidecarenone of humans and mammals are 10 prenyl units, thus it is called Ubidecarenone. Ubidecarenone plays an important role in proton translocation in vivo respiratory chain and electron transfer , it is the cell respiration and cell metabolism activator, and also an important antioxidant and non-specific immune enhancer. Modern biology study found that excess free radicals in the body can cause damage to the genetic material of the cell membrane, and macro manifested as aging, cancer and other symptoms. Free radical scavenging process is commonly referred to as "antioxidant." We know that life activities is driven by a variety of enzymes. Enzymes are large proteins, enzymes need some small molecules to help in exercising some functions , these substances are called "coenzyme." Ubidecarenone exists in the mitochondria within the cells. Mitochondria are the place to produce energy in cells, many enzymes and other molecules are involved in the energy production process, and Ubidecarenone is one of the indispensable one. In the organs with more energy consumption in the human body , the content of Ubidecarenone will be relatively high, such as heart, liver, kidney, kidney, spleen, pancreas, adrenal, the content is particularly rich. The total body content of Ubidecarenone is only 500-1500mg, the content changes with age, it decreased for most people after the age of 20 . Lack of Ubidecarenone are usually caused heart failure, gum disease, arrhythmias, stroke, hypertension (blood pressure, food), heart disease, arteriosclerosis, cancer, Parkinson's disease, muscular dystrophy, AIDS. Ubidecarenone can successfully prevent and treat these diseases, from 40 years ago when it was found and isolated, Ubidecarenone has been conducted hundreds of clinical studies, a lot of evidence shows that nutrition is necessary for health (health food) .

Biological Activity

Component of the mitochondrial transporter chain that behaves as a powerful antioxidant. Displays neuroprotective activity.

Discovery History

Ubidecarenone was discovered in 1957, Dr. Frederick Crane identified the chemical structure in 1958 , and received the highest honor of the American Chemical Society Priestly Medal. He is known as the father of the study of Ubidecarenone, he proposed Ubidecarenone to play an important role in heart function. In real life, Dr. Frederick Crane has been taking Q10 for 40 years, until his death at 91 years old, he had been an active energetic professors engaged in research activities. In 1978, Dr. Peter (Peter), the University of Edinburgh, Scotland, first discovered Ubidecarenone must participate in human cells energy production , and thus obtained Nobel prize. Today, Europe, Japan and other developed countries have incorporated the content of Ubidecarenone in the human body as a measure of the level of of the health of the body as an important indicator.
Ubidecarenone exists in every cell of the human body, the main role is to drive the body cells to produce energy, it can accelerate cell renewal, stimulate cell activity, thus greatly promoting the cells' ability to uptake nutrients. Ubidecarenone ingredients in skin care products can effectively help the skin cells to active the absorption of other nutrients in skin care products , so skin care ingredients is no longer simply to stay on the skin surface, when reaching the underlying skin, it can quickly provide additional protecting energy for skin protection factor. If a person becomes a car for analogy, the Ubidecarenone is equivalent to the "engine", without engine, the car can not travel, without Ubidecarenone, the body can not produce the "power" to carry out daily operations.
The above information is edited by the Chemicalbook of Tian Ye.


A mitochondrial transporter chain component


Antibacterial and antioxidant for preventing and treating cancer.

What role in the human body

Ubidecarenone has two main functions in the body, the first is playing an important role in the process of transferring nutrients into energy in the mitochondria, the second is a clear anti-lipid peroxidation effect.
It is well known that free radicals generation is the the main reasons of aging. Most cells contain between 500 to 2,000 mitochondria. These mitochondrial act like a little "energy factory", transferring the food we eat into energy, thereby to maintain the operation of life. Ubidecarenone is a metabolic activator, it can activate cell respiration, accelerate the production of the energy needed by the body----adenosine triphosphate (ATP). Studies have shown that once human blood Ubidecarenone levels reduced by 25%, the body's major organs (especially the heart) will no maintain optimum operating condition because of insufficient energy. Studies have shown that antioxidants can prevent and reduce the risk of incidence of many diseases. Ubidecarenone can be synthesized in the human tissue, after age 20, the synthesis will be weakened, the liver loses the ability to synthesize Ubidecarenone, while Ubidecarenone is also difficult to obtain from the food supplement. In addition to age, bad habits, stress and infections can affect the body, resulting in not enough supply of Ubidecarenone, the body will gradually reduce the natural coenzyme in cells, which means that the body's cells gradually lose their protection. Thus accelerating the skin aging process.
