Hepatic lipase often found bound to HSPG, heparan sulfate proteoglycans (HSPG), keeping HL inactive and unable to bind to HDL (high density lipoprotein) or IDL (intermediate density lipoprotein). When it is free in the bloodstream, however, it is found associated with HDL to maintain it inactive. This is because the triacylglycerides in HDL serve as a substrate, but the lipoprotein contains proteins around the triacylglycerides that can prevent the triacylglycerides from being broken down by HL. One of the principal functions of hepatic lipase is to convert intermediate-density lipoprotein (IDL) to low-density lipoprotein (LDL). Hepatic lipase thus plays an important role in
Nominalized adjective number and nominative case. "Den Alten" is a similar inflection but in the accusative case. The nominalized adjective is derived from the adjective "alt" and surfaces as it does by taking the appropriate inflection. Like in English, adjectival nouns are used as a plural definite ("the unemployed") and with nationality words ("the Swedish"). However, Swedish does not require "one or ones" with count nouns ("The old cat is slower than the new (one)").
