Globin vs. Globulin: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 7, 2024
Globin is a protein component of hemoglobin in red blood cells, while globulin is a group of proteins in blood plasma involved in immune responses.

Key Differences

Globin is a protein that binds to heme in hemoglobin, essential for oxygen transport in blood. Globulin encompasses various proteins in blood plasma, playing key roles in immunity and clotting.
The structure of globin is crucial for its ability to bind and release oxygen effectively. Globulin proteins, like immunoglobulins, are critical for immune responses and fighting infections.
Variations in globin can lead to disorders like sickle cell anemia. Different types of globulin proteins, such as alpha, beta, and gamma globulins, have distinct functions in blood regulation and defense.
Research into globin genes aids in understanding genetic blood disorders. Studies on globulin levels can indicate various health conditions, including liver function and autoimmune diseases.
Globin is integral to the function of red blood cells. In contrast, globulin proteins contribute to the overall homeostasis and defense mechanisms of the body.

Binding globulins carry hormones through the bloodstream.


Globin genes determine the specific type of hemoglobin.
Beta globin gene mutations lead to sickle cell disease.


Globulins include antibodies that fight infections.
Immunoglobulins are a type of globulin crucial for immunity.


Globin plays a key role in red blood cell function.
Abnormal globin affects the oxygen-carrying capacity of blood.


Abnormal globulin levels can indicate health issues.
Elevated globulin levels may suggest an autoimmune disorder.


Globin is a protein in hemoglobin that carries oxygen.
Mutations in globin genes can cause anemia.


Globulin proteins aid in blood clotting processes.
Certain globulins are essential for wound healing.


Globin is studied for insights into blood diseases.
Research in globin gene therapy offers hope for genetic blood disorders.


Globulin is a major group of proteins in blood plasma.
Globulin levels are tested to assess liver function.


Any of a group of heme-containing proteins, including myoglobin and hemoglobin, that can bind oxygen and other gases.


Any of a class of proteins that are widespread in blood plasma, milk, muscle, and plant seeds and that are insoluble in pure water but soluble in dilute salt solutions. Blood serum globulins are divided into several groups, including the alpha, beta, and gamma globulins.


(protein) Any globular protein that incorporates a lang=en.


The protein fraction of blood serum containing the globulins; serum globulin.


(protein) One of several polypeptides that are the protein components of haemoglobin or myoglobin.


(protein) Any of a group of simple proteins, soluble in water only in the presence of salts, that are coagulated by heat


A colorless protein obtained by removing heme from hemoglobin; the protein part of hemoglobin.


An albuminous body, insoluble in water, but soluble in dilute solutions of salt. It is present in the red blood corpuscles united with hæmatin to form hæmoglobin. It is also found in the crystalline lens of the eye, and in blood serum, and is sometimes called crystallin. In the plural the word is applied to a group of proteid substances such as vitellin, myosin, fibrinogen, etc., all insoluble in water, but soluble in dilute salt solutions.


A colorless protein obtained by removing heme from hemoglobin; the oxygen carrying compound in red blood cells


A family of proteins found in blood and milk and muscle and in plant seed
