p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6] The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.
4-Toluenesulfonyl chloride (p-toluenesulfonyl chloride, toluene-p-sulfonyl chloride) is an organic compound with the formula CH 3 C 6 H 4 SO 2 Cl. This white, malodorous solid is a reagent widely used in organic synthesis. [2] Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride (−SO 2 Cl) functional group.
Clinical nutrition centers on the prevention, diagnosis, and management of nutritional changes in patients linked to chronic diseases and conditions primarily in health care. Clinical in this sense refers to the management of patients, including not only outpatients at clinics and in private practice, but also inpatients in hospitals.
The blood type diets are fad diets [1] advocated by several authors, the most prominent of whom is Peter J. D'Adamo. [2] These diets are based on the notion that blood type, according to the ABO blood group system, is the most important factor in determining a healthy diet, and each author recommends a distinct diet for each blood type.
The Mayo Clinic Diet is a diet book first published in 1949 by the Mayo Clinic's committee on dietetics as the Mayo Clinic Diet Manual. [1] Prior to this, use of the term "diet" was generally connected to fad diets with no association to the clinic.
Polystyrene sulfonic acid, the acid whose salts are the polystyrene sulfonates, has the idealized formula (CH 2 CHC 6 H 4 SO 3 H) n. The material is prepared by sulfonation of polystyrene: (CH 2 CHC 6 H 5) n + n SO 3 → (CH 2 CHC 6 H 4 SO 3 H) n. Several methods exist for this conversion, which can lead to varying degree of sulfonation.
p-Toluenesulfonyl hydrazide is the organic compound with the formula CH 3 C 6 H 4 SO 2 NHNH 2. It is a white solid that is soluble in many organic solvents but not water or alkanes. It is a white solid that is soluble in many organic solvents but not water or alkanes.
Nutrition scientists began to refine this hypothesis in the early 20th century, emphasizing the role of negatively charged particles and positively charged particles in food. Diets high in chloride , phosphate and sulfate (all of which are anions) were presumed to be acid forming, while diets high in potassium , calcium and magnesium (all of ...
