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.
The primary structure of protamine P1, the protamine used for packaging DNA in sperm cells, in placental mammals is usually 49 or 50 amino acids long. This sequence is divided into three separate domains: an arginine-rich domain for DNA binding flanked by shorter peptide sequences containing mostly cysteine residues.
