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
Adjective phrase English is that an attributive adjective alone generally precedes the noun, e.g. "a proud man", whereas a head-initial or head-medial adjective phrase follows its noun, e.g. "a man proud of his children". A predicative adjective (phrase), in contrast, appears outside of the noun phrase that it describes, usually after a linking verb, e.g. "The man is proud of his children". There is a tendency to call a phrase an "adjectival phrase" when that phrase is functioning like an adjective phrase, but is not actually headed by an adjective. For example, in "Mr Clinton is a man of wealth", the prepositional
