The complex of cholesterol or triglyceride and protein is known as what?

The correct terminology for a complex of cholesterol or triglyceride and protein is lipoprotein. Lipoproteins play a crucial role in the transport of lipids, such as cholesterol and triglycerides, through the bloodstream, where these lipids are not soluble in water. The structure of lipoproteins allows them to be soluble in blood; they consist of a core of lipids surrounded by a shell of proteins, making lipid transport efficient.

Phospholipids, while also involved in forming cell membranes, contain a glycerol backbone, two fatty acids, and a phosphate group. They are a different class of molecules.

Amphipathic molecules have both hydrophobic (water-repelling) and hydrophilic (water-attracting) properties, but the term does not specifically refer to complexes of lipids and proteins like lipoproteins do.

Triglycerides, on the other hand, are a type of lipid made of three fatty acids attached to glycerol, and they do not contain proteins in their structure. Thus, they don’t fit the description of a complex with proteins.

Overall, lipoproteins are essential for lipid transport in the body and differ significantly from the other options listed, which lack the specific protein component in
