Journal ArticleDOI
TL;DR: A microprocedure for the direct determination of triglyceride concentrations in biologic specimens is presented and depends on the quantitative removal of phosphatides from the sample and the subsequent determination of esterified glycerol.

TL;DR: “Free” and “total” glycerol, measurable after alcoholic saponification, are determined by Glycerolkinase in a three-step enzymatic proof-reaction by means of micro-methods.
Abstract: Die Neutralfette im Blutserum und Gewebe lassen sich uber Glycerin exakt ermitteln. „Freies“ und nach alkoholischer Verseifung nachweisbares „Gesamt“-Glycerin werden mit Glycerokinase in einer dreistufigen enzymatischen Nachweisreaktion im Mikroverfahren bestimmt. Die Differenz wird als „Glycerid-Glycerin“ angesprochen. Reaktionsprinzip, Durchfuhrung der Methode und Berechungsweise werden ausfuhrlich besprochen. Fur freies Glycerin werden 0,2 ml Serum, fur Gesamtglycerin etwa 0,007–0,015 ml Serum aquivalente Hydrolysatmengen in den Test eingesetzt. Bei einer „Empfindlichkeit“ von 0,0008 µMol (wenn bei 340 nm, bzw. 0,0015 µMol Glycerin, wenn bei 366 nm gemessen wird), konnen noch 1/20 bis 1/10 des im Normalserum vorhandenen freien bzw. Gesamtglycerins mit den Standardansatzen erfast werden. Die obere Nachweisgrenze reicht dann bis 0,15 bzw. 0,3 µMol Glycerin, das entspricht der 8- bzw. 15fachen Normalmenge fur freies und Gesamtglycerin. In den angegebenen Grenzen liegen die uber Glyceridglycerin nachweisbaren Triglyceridkonzentrationen. Empfindlichkeit und obere Nachweisgrenze konnen durch andere Serum- bzw. Hydrolysatmengen in weiten Grenzen variiert und der jeweiligen Fragestellung angepast werden.

Journal ArticleDOI
TL;DR: A lipase activity present in adipose tissue of both rats and rabbits which exhibits a marked specificity for hydrolysis of monoglycerides is investigated and evidence indicating that this activity is distinct from the hormone-sensitive lipase activit’y and probably also from lipoprotein lipase is presented.
