simple protein
Definition
Noun: A simple protein is a type of protein that, when broken down through hydrolysis, yields only amino acids as its constituent parts. It is not combined with or conjugated to other non-protein molecules (like carbohydrates or lipids).
Usage
The term is used in biochemistry and nutrition to classify proteins based on their composition and products of hydrolysis. - Albumin and globulin are classic examples of simple proteins. - The experiment aimed to isolate the simple protein from the complex mixture.
Advanced Usage
- In Nutritional Contexts: Simple proteins are contrasted with conjugated proteins (which contain non-amino acid components) and derived proteins (which are products of protein breakdown).
- A diet must provide adequate amounts of both simple and conjugated proteins for proper bodily function.
Variants and Related Words
- Conjugated Protein (n): A protein that is bonded to a non-protein component (a prosthetic group), such as a glycoprotein or lipoprotein.
- Derived Protein (n): A product resulting from the partial breakdown or modification of a protein, such as peptides or peptones.
Synonyms
- Holoprotein (when referring specifically to the protein part without its prosthetic group, though this is a more technical synonym).
Related Phrases and Concepts
- Protein Hydrolysis: The chemical process of breaking down a protein into its amino acids using water, which is the defining test for a simple protein.
- Complete protein hydrolysis confirms it is a simple protein.
- Amino Acid Sequence: The primary structure of a simple protein, which is a linear chain of amino acids.
Noun
-
a protein that yields only amino acids when hydrolyzed
