The Importance of the Different Lipid Molecule Protein Types

membrane protein types

Meta Data: Even though protein is important and very essential to the body, people do not understand the sources important and types of protein. This article will expose you to the types of protein and importance of protein.

Depending on the exact positions and inter-connections of a cell in the body, membrane protein types are usually classified as six different types, each type having a specific function. Here, in brief, we look at the six major types.

Types of Protein

MPT: This is a phospholipid protein, which is a dimethylated membrane protein which allows two hydrogen atoms to link together. When bound together, it allows a cell to pass water along with the nutrients. In addition, it helps to transport proteins in and out of the cell. Mpt is generally found in blood cells.

PPT: Like MPT, PPT is a phospholipid protein. However, PPT can also be a cholesterolipid or triglyceride. Cholesterolipids have been linked to heart disease. Triglycerides on the other hand, are found in the fat cells and have been shown to raise bad cholesterol levels in the body.

APT: APT is a transmembrane protein that functions as a receptor for a variety of lipophiles. APT is usually found on the outer surface of a cell. It helps in the entry of lipophilic into the cell and in transporting lipophiles out of the cell.

MPQ: As the name suggests, MPQ functions as a lipoprotein receptor. However, unlike APT, MPQ is not a transmembrane protein.

RPL: As the name suggests, RPL works as a lipoprotein receptor on its own. Instead of binding lipophiles to its receptor, it instead binds to other lipophiles found on the cell membrane. As such, it is able to accept a variety of lipophiles. RPL is commonly found in the liver and pancreas.

PLP: While it does not bind to lipophiles on its own, PLP is found to be able to bind to lipophiles bound by other proteins on its receptor. PLP is commonly found in the kidney, spleen, intestine and lungs.

Functions of the Six Forms of Membrane

These six forms of membrane protein perform different functions. However, they all basically perform the same functions – they bind to a lipid molecule to enable a process called uptake. Once the nutrient or electrolyte is in, a particular membrane protein in that location starts to move it around the cell in various ways. In the case of MPT, it moves it across the membrane and into the blood stream where it is transported to wherever it is needed.

The membrane protein types that are found on the cell membrane are called lipidophiles. Each membrane protein has a specific job to perform, and some of them perform the same jobs for different types of lipids.


The APT membrane protein is used in the kidneys to transport fluids from the blood to various parts of the body. The PPT is involved in transporting fluids from the blood to the liver. the pancreas. The PLP in the liver is responsible for transporting nutrients into the liver.

The RPL in the kidney transports fluids back into the blood. the kidney after the kidney is full of them. The MPT performs the same function, only with a slightly different approach. It binds to lipophiles bound by other proteins and transports them to where they are needed.

The PLP in the intestine transports lipids from the intestine into the bloodstream. The PLP in the pancreas transports lipids back into the bloodstream after the kidney is full of them.

The MPQ in the liver transports lipids from the liver into the liver. The PLP in the intestine is responsible for transporting nutrients into the liver after the kidney has taken care of transporting nutrients into the intestines. In this case, the membrane protein is responsible for moving nutrients into the liver.
