The transport of lipid-soluble hormones in the blood is accomplished by which of the following mechanisms

Question

Quizplus · Accepted Answer

Lipid-soluble hormones are hydrophobic and do not dissolve in blood plasma, which is mostly water. Therefore, they need to bind to some plasma proteins (such as albumin or sex hormone-binding globulin) to be transported in the blood. This binding provides a means of carrying the hormone through the watery bloodstream without affecting its chemical structure or decreasing its concentration. Loose binding with iodine and specific binding to HDLs or glycolipids are not mechanisms involved in the transport of lipid-soluble hormones in the blood.
