Heparin polysaccharide

Heparin was discovered by Jay McLean and William Henry Howell in 1916, although it did not enter clinical trials until 1935. It was originally isolated from dog liver cells, hence its name (ἧπαρ hepar is Greek for 'liver'; hepar + -in). McLean was a second-year medical student at Johns Hopkins University, and was working under the guidance of Howell investigating pro-coagulant preparations, when he isolated a fat-soluble … Web20 feb. 2015 · Furthermore, we discovered that the enhancing effects of SP, SEM, and SEVI can be significantly reduced by heparin, a sulfated polysaccharide with an anionic charge. It is probable that heparin abrogates said enhancing effects by interfering with the interaction of the viral particle and the amyloids, which interaction results in the binding of …
