Question: how are ldl and hdl difference functionally?
Answer: Since protein is more dense than fat, HDL particles are more dense than LDL particles, hence the names "high-density" and "low-density" lipoproteins" (Kamps, n.d.). Another structural difference between LDL and HDL are their proteins. LDL carries B-100 proteins whereas HDL carries A-I and A-II proteins (Kamps, n.d.).
