Lipoproteins are composed solely of proteins.

Verified step by step guidance
1
Understand the role of lipoproteins: Lipoproteins are complexes that transport lipids, such as cholesterol and triglycerides, through the bloodstream. They are essential for lipid metabolism and distribution in the body.
Examine the composition of lipoproteins: Lipoproteins are not composed solely of proteins. They consist of a core of lipids surrounded by a shell of proteins, phospholipids, and cholesterol, which helps them remain soluble in blood.
Identify the synthesis location of lipoproteins: Lipoproteins are not synthesized exclusively in the pancreas. They are primarily synthesized in the liver and intestines, where they are assembled and released into the bloodstream.
Clarify the storage and energy role of lipoproteins: Lipoproteins are not stored in the liver as a primary energy source. Instead, they transport lipids to various tissues, where the lipids can be used for energy or stored.
Conclude with the correct statement: Based on the analysis, the true statement is that lipoproteins are responsible for transporting lipids in the blood, facilitating their movement to tissues for metabolism or storage.
