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
Postpositive adjective Postpositive adjective A postpositive or postnominal adjective is an attributive adjective that is placed after the noun or pronoun that it modifies. This contrasts with prepositive adjectives, which come before the noun or pronoun. In some languages the postpositive placement of adjectives is the normal syntax, but in English it is less usual, largely confined to archaic and poetic uses (as in "They heard wights unseen), phrases loaned from Romance languages or Latin (such as "heir apparent, "aqua regia"), and certain particular grammatical constructions (as in "those anxious to leave"). Recognizing postpositive adjectives in English is important for determining the
