Sinistrin
Sinistrin
Sinistrin (pronunciation: /sɪˈnɪstrɪn/) is a type of polysaccharide that is derived from the tuber of the Jerusalem artichoke (Helianthus tuberosus). It is a type of inulin, a group of naturally occurring polysaccharides produced by many types of plants.
Etymology
The term "sinistrin" is derived from the Latin word "sinister", meaning "left". This is in reference to the left-handed helical structure of the inulin-type fructans, of which sinistrin is a member.
Usage
Sinistrin is primarily used in medical research as a marker to measure the glomerular filtration rate (GFR) in the kidneys. It is injected into the bloodstream and its rate of clearance from the body is measured. This provides an accurate assessment of kidney function.
