The Dosage Index is a mathematical figure used by breeders of Thoroughbred race horses, and sometimes by bettors handicapping horse races, to quantify a horse's ability, or inability, to negotiate the various distances at which horse races are run. It is calculated based on an analysis of the horse's pedigree.
By comparing the values for horses in a given race, a bettor can identify which horses have a more speed oriented pedigree, and which have a more stamina oriented pedigree. From a breeding point of view, stallions with a low AWD number are considered to be speed influences, and may be bred to mares whose broodmare sire has a higher number to ...
In the laboratory, this liquid serves as a source of HCN, which is inconveniently volatile. [4] Thus, acetone cyanohydrin can be used for the preparation of other cyanohydrins, for the transformation of HCN to Michael acceptors, and for the formylation of arenes. Treatment of this cyanohydrin with lithium hydride affords anhydrous lithium cyanide:
Another synthetic pathway for α-hydroxy acids involves the addition of hydrogen cyanide to ketones or aldehydes, followed by the acidic hydrolysis of the cyanohydrin intermediate. [14] R−CHO + HCN → R−CH(OH)CN R−CH(OH)CN + 2H 2 O → R−CH(OH)CO 2 H + NH 3
In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion ...
What Is Compounded Tirzepatide? This article was reviewed by Craig Primack, MD, FACP, FAAP, FOMA. If you’re starting a weight loss journey, you might have stumbled upon tirzepatide — the drug ...
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
The elevation of Elizabeth Warren as the top Democrat on a key Senate banking panel could mean some headaches for Wall Street financial giants in 2025.
