Simple Protein vs. Conjugated Protein: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 8, 2024
Simple proteins are made only of amino acids. Conjugated proteins contain a protein part plus a non-protein group (prosthetic group).

Key Differences

Simple proteins are composed solely of amino acids and yield only amino acids upon hydrolysis. Conjugated proteins have a prosthetic group in addition to the amino acids.

When hydrolyzed, simple proteins break down into their constituent amino acids. In contrast, conjugated proteins yield both amino acids and their specific non-protein parts.

Examples of simple proteins include albumin and globulin, crucial for various biological functions. Conjugated proteins include hemoglobin, which contains a heme group along with the protein part.

The structure of simple proteins is determined by the sequence and nature of the amino acids. Conjugated proteins have a more complex structure due to the presence of the prosthetic group.

In biological processes, simple proteins often play roles in structure and enzymes. Conjugated proteins are involved in more specialized functions like transport and storage of other molecules.
