Secosteroid cholecalciferol

Structural relationship of vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol) with their respective provitamins, cholesterol, and a classic steroid hormone, cortisol (see inset box). The two structural representations presented at the bottom for both vitamin D 3 and vitamin D .2 are equivalent; these are simply different ways of drawing the same molecule. It is to be emphasized that vitamin D 3 is the naturally occurring form of the vitamin; it is produced from 7-dehydrocholesterol, which is present in the skin, by the action of sunlight (see Figure 2). Vitamin D 2 (which is equivalently potent to vitamin D 3 in humans and many mammals, but not birds) is produced commercially by the irradiation of the plant sterol ergosterol with ultraviolet light.

My theory is that people with 1,25(OH) toxicity have already high 1,25(OH) levels for some reason or cholecalciferol is metabolized by CYP2D6. I’m slow metabolizer, and if any med I’m taking is metabolized by CYP2D6, I got toxicity symptoms since day one. I need to take a quarter of the therapeutic dose so my body could use this medicine correctly. On the other hand, fast metabolizers need to take 4x of the therapeutic dose. It would explain why doses of D3 varies so much in people’s statements. Of course, it’s a fat-soluble vitamin, so weight is an important factor when you adjust the dose, but the pace of your’s liver metabolization is even more important IMO.

Salivary Pathogen Molecular Testing – we strongly encourage all or our clients to have a simple saliva molecular test (provided at our clinic) to determine definitively and quantitatively which periodontal pathogens are present in their infection .  Every case is different. This highly definitive test directs treatment therapy moving forward and provides valuable information about the decision to use adjunctive systemic antibiotics . This is considered “individualized periodontal medicine” since we are not guessing about virulent pathogen involvement, thus we can pinpoint the appropriate short term antibiotic for the infection.  Health history factors and medical lab test results are take into account before any definitive decisions are made for appropriate therapy moving forward.  We often involve the medical doctor (or specialist, such as a cardiologist) in the decision making process based on systemic health issues already present. For example, if a patient has a history of heart disease, atherosclerosis, or stroke, and the molecular pathogen test returns with high levels of certain pathogens known to contribute to vascular inflammation , we are going to be much more proactive in our multidisciplinary treatment approach.  This would mean more frequent pathogen testing and possibly a much more frequent supportive periodontal maintenance program. This also empowers the patient through education, if the patient is educated to understand the mouth-body connection, and how it can relate to serious systemic diseases, they can become more involved in their own co-therapy.

Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [38] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [39] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [39]
