But if you ask a student to find the number of degrees between the hands of a clock at 4:08, then this is more interesting math problem. What if you pose the problem in this way: Find the number of degrees between the hands of a clock at 4:08.
Protamine sulfate is a drug that reverses the anticoagulant effects of heparin by binding to it.Protamine was originally isolated from the sperm of salmon and other species of fish but is now produced primarily through recombinant biotechnology.It is a highly cationic peptide that binds to either heparin or low molecular weight heparin (LMWH) to form a stable ion pair, which does not have anticoagulant activity.rotamine was originally isolated from the sperm of salmon and other species of fish but is now produced primarily through recombinant biotechnology.
Histamine is an organic nitrogenous compound involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter.Histamine is involved in the inflammatory response and has a central role as a mediator of pruritus.istamine base, obtained as a mineral oil mull, melts at 83-84 Â°C. Hydrochloride and phosphorus salts form white hygroscopic crystals and are easily dissolved in water or ethanol, but not in ether. In aqueous solution, histamine exists in two tautomeric forms: NÏ-H-histamine and NÏ-H-histamine.
