Verified step by step guidance1
Step 1: Understand the composition of blood plasma, which is the liquid component of blood containing various proteins, nutrients, hormones, and waste products.
Step 2: Identify the major types of plasma proteins, which include albumins, globulins, and fibrinogen, each serving different functions such as maintaining osmotic pressure, immune response, and blood clotting respectively.
Step 3: Recall that hemoglobin is not a plasma protein but is found inside red blood cells, responsible for oxygen transport.
Step 4: Recognize that among plasma proteins, albumins are the most abundant in adult blood plasma, playing a key role in maintaining blood osmotic pressure and transporting substances.
Step 5: Conclude that the most abundant proteins in adult blood plasma are albumins, not fibrinogen, hemoglobin, or globulins.
