what are some roles of the liver in the metabolism of lipids?
converts fats into proteins
synthesizes lipoproteins, phospholipids, and cholesterol
oxidizes fatty acids

Explanation:

• The liver does not convert fats into proteins. Lipid and protein metabolism are distinct processes.
• The liver is responsible for synthesizing lipoproteins (like VLDL - very low - density lipoprotein), phospholipids, and cholesterol. Lipoproteins are important for transporting lipids in the bloodstream, phospholipids are part of cell membranes, and cholesterol has various functions including being a precursor for steroid hormones.
• The liver oxidizes fatty acids. Through beta - oxidation, fatty acids are broken down in the liver (and other tissues to some extent) to produce acetyl - CoA, which can enter the citric acid cycle for energy production.

Answer:

• B. synthesizes lipoproteins, phospholipids, and cholesterol
• C. oxidizes fatty acids
