The plasma protein that requires fat-soluble vitamins to be carried in the blood is lipoprotein. Specifically, lipoproteins transport fat-soluble vitamins such as A, D, E, and K, which are absorbed in the intestine along with dietary fats. These vitamins are incorporated into lipoproteins, allowing them to be solubilized and transported through the aqueous environment of the bloodstream.
What else can I help you with?
Which plasma protein is soluble in plasma?
Albumin is the most abundant plasma protein that is soluble in plasma. It plays a crucial role in maintaining oncotic pressure and transporting various substances, including hormones, vitamins, and drugs. Other soluble plasma proteins include globulins and fibrinogen, but albumin is the primary protein responsible for maintaining the osmotic balance in the bloodstream.
How long do vitamins stay in your body?
vitamins are of two types-- water soluble and fat soluble. water soluble vitamins can not be stored for long as they get excreted dissolved in water in urine. but fat soluble vitamins can be stored for long in our body as these vitamins, dissolved in fats, can be stored in adipose tissues.
Fibrinogen is an insoluble plasma protein?
Fibrinogen is a soluble plasma protein that plays a key role in blood clot formation. When activated by thrombin during the clotting process, fibrinogen is converted into fibrin, which forms a mesh that helps to trap blood cells and platelets to form a stable clot.
Is prothrombin soluble?
Prothrombin is a soluble protein found in blood plasma. It plays a key role in the blood clotting process by being converted into thrombin, which helps form a blood clot.
Which of the following plasma lipoproteins is the most soluble?
Lipoproteins are soluble in lipids; plasma is a suspension in blood.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.
How does thyroxine pass through the plasma membranes?
diffusion. it is lipophilic and is able to pass through the PM. thyroxine is not water soluble and is the reason why it requires a carrier protein (albumin) for circulation.
What is the difference between fibrin and fibrinogen?
Fibrinogen is a plasma protein and functions in blood coagulation.Fibrin are threads of protein that provide the backbone for a blood clot.
Is hemoglobin a plasma protein?
No, hemoglobin is not a plasma protein. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. Plasma proteins are different types of proteins found in the liquid component of blood called plasma.
Write the normal value of plasma protein?
Plasma proteins are proteins that are present in blood plasma. The normal laboratory value of plasma total protein is around 7 g/dL.
Which plasma protein changes fibrinogen into fibrin?
The plasma protein that changes fibrinogen into fibrin is thrombin. Thrombin is an enzyme that plays a crucial role in the blood coagulation process, converting soluble fibrinogen into insoluble fibrin strands, which form the mesh structure of a blood clot. This transformation is essential for hemostasis, preventing excessive bleeding following injury.
Is albumin hydrophillic?
Yes, albumin is a water-soluble and hydrophilic protein found in blood plasma. It plays a crucial role in maintaining osmotic balance and transporting various molecules in the circulatory system.
