Final answer:
If the body had a high proportion of lipoproteins with little protein, it would lead to lower density lipoproteins (LDLs), which are associated with the buildup of plaque in arteries, increasing the risk of atherosclerosis, heart attacks, and strokes.
Step-by-step explanation:
If the body carried a large proportion of lipoprotein molecules that contained little protein, there would be significant health risks involved. Lipoproteins are essential for the transportation of lipids such as cholesterol through the blood, as they are not water-soluble. When the lipoprotein has a lower protein content and higher lipid content, it results in a lower density lipoprotein (LDL).
LDLs, often referred to as 'bad cholesterol,' can lead to the buildup of plaque in the arteries (atherosclerosis) if they are present in high levels. This buildup restricts blood flow and can cause inflammation, tissue death, and can lead to severe conditions such as heart attacks or strokes.
Proteins are key components of lipoproteins that help manage the transportation and removal of cholesterol from the body, and a lack of protein in these molecules would impair this process, potentially raising cholesterol levels and contributing to cardiovascular diseases.
