Docosatetraenoic acid (DTA) is a very long chain omega-6 fatty acid with 22 carbons and 4 double bonds (22:4n6).

It is synthesized by adding 2 carbons atoms to the backbone of arachidonic acid using the elongase enzyme. It is sometimes referred to by its common name adrenic acid and is one of the most abundant fatty acids in the early human brain and the adrenal gland. DTA has not been well studied, though it has recently been shown to have important physiologic functions. It is now believed to be a pro-resolving mediator in inflammation by blocking neutrophilic metabolites and dampening the inflammation response. For example, in osteoarthritis DTA enhances phagocytosis by macrophages which clears products of cartilage breakdown in the joint space. Supplementation of DTA is being studied as a promising intervention in osteoarthritis to dampen inflammation and prevent structural damage.

Docosatetraenoic acid is also known as Adrenic acid / Adrenate.

Docosatetraenoic acid is a member of the class of compounds known as very long-chain fatty acids.

Fatty acids belong to one of three types or families: saturated, monounsaturated and polyunsaturated. These names describe the structure of the fatty acid in terms of whether it is fully loaded with hydrogen.

The Dog Dander IgE test measures the specific immune response to proteins found in dog skin flakes, saliva, and urine, collectively known as "dander." IgE, or Immunoglobulin E, is an antibody that your immune system releases when it detects allergens, like dog dander, in sensitive individuals. High levels of Dog Dander IgE suggest that your immune system reacts to these proteins, often causing symptoms like sneezing, itching, or wheezing.

If you experience allergy-like symptoms around dogs, a high Dog Dander IgE result can confirm a sensitivity. Knowing this can guide you in managing exposure and exploring options to reduce symptoms, such as allergy medications or specialized treatments.

Dopac (aka 3,4-Dihydroxyphenylacetic acid) is a metabolite of the neurotransmitter dopamine. Dopamine serves as the reward and pleasure center in the brain. DOPAC and HVA (Homovanillic Acid) are dopamine metabolites.

DOPAC levels, when viewed in conjunction with dopamine levels, may provide insight into how the body processes neurotransmitters.

Dopamine is largely responsible for regulating the pleasure reward pathway, memory and motor control. Its function creates both inhibitory and excitatory action depending on the dopaminergic receptor it binds to. Memory issues are common with both elevations and depressions in dopamine levels. Caffeine and other stimulants, such as medications for ADD/ADHD, often improve focus by increasing dopamine release, although continual stimulation of this release can deplete dopamine over time.

Dopamine is a chemical found naturally in the human body. It is a neurotransmitter, meaning it sends signals from the body to the brain. Dopamine plays a part in controlling the movements a person makes, as well as their emotional responses. The right balance of dopamine is vital for both physical and mental wellbeing.

Dopamine is a neurotransmitter that activates the brain’s reward center during pleasurable activities.

Optimal dopamine function is involved in many aspects of health, including memory, movement, motivation, mood, attention, sleep, arousal, learning, and lactation.

What is dopamine and what are its functions?

Dopamine is a neurotransmitter (= chemical messenger) that is produced in large concentrations during pleasurable activities such as when eating sugar or junk food, having sex, or participating in fun and enjoyable down-time activities like spending time in nature or engaging in a favorite hobby. Dopamine is released during these times as a reward for engaging in the activities necessary for survival and reproduction such as eating, drinking, and competing.

Dopamine is widely distributed throughout the central nervous system and is involved in the control of movement.

In a Catecholamines, Fractionated, Random Urine test, dopamine is one of the catecholamines measured. Catecholamines are a group of hormones and neurotransmitters that include substances like epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. These chemicals play essential roles in the body's nervous system and its response to stress.

Dopamine is a key neurotransmitter involved in motivation, focus, movement, and emotional balance. On the Neurotransmitter XL panel, it’s measured alongside related catecholamines and cofactors to provide a complete view of the body’s stress and reward chemistry. Synthesized from tyrosine and dependent on nutrients like vitamin B6, iron, BH4, and magnesium, dopamine plays a vital role in both brain and autonomic function. The test evaluates dopamine production, breakdown (via COMT and MAO enzymes), and metabolic context, including methylation capacity (SAM/SAH ratio) and mitochondrial energy markers. Interpreted in combination with noradrenaline, serotonin, GABA, glutamate, and tryptophan metabolites, dopamine results help clarify whether mood and energy issues stem from neurotransmitter depletion, stress-related overactivity, or cofactor deficiencies. This biomarker provides essential insight into how the body regulates drive, alertness, and emotional resilience.

What is Dorea?

Dorea is a genus of bacteria that resides in the human gut as part of the normal intestinal microbiome. It is a Gram-positive, anaerobic bacterium from the Lachnospiraceae family, a group known for producing short-chain fatty acids and fermenting dietary fiber.

Although Dorea is considered a commensal organism (not inherently harmful), its presence and abundance in the gut can offer clues about your digestive efficiency, gas production, inflammation levels, and overall microbial balance.

Dorea is a genus within the Lachnospiraceae family that is in the Firmicutes phylum. Dorea species are known to produce hydrogen and carbon dioxide as end-products of glucose fermentation and may be associated with bloating.
