Which protein accounts for 36% of the dissolved proteins within plasma and influences lipid-soluble vitamins?

The protein that accounts for 36% of the dissolved proteins within plasma and has a significant role in influencing lipid-soluble vitamins is albumin. Albumin is the most abundant plasma protein and serves various functions, including maintaining oncotic pressure and transporting substances such as fatty acids, hormones, and lipid-soluble vitamins (A, D, E, and K).

Its structure allows it to bind these vitamins and facilitate their transport in the bloodstream, which is essential for their distribution and function within the body. This transport capability highlights albumin's critical role in metabolism and nutrient delivery, especially for compounds that are not easily soluble in plasma.

While globulins, fibrinogen, and coagulation factors are also important plasma proteins, their primary functions differ from that of albumin. Globulins are involved in immune response and transport of various molecules. Fibrinogen plays a vital role in blood clotting, while coagulation factors are specifically related to the blood coagulation process. None of these proteins have the same level of influence on lipid-soluble vitamins as albumin does.
