proteose
Definition
Noun (Biochemistry): A water-soluble, non-heat-coagulable mixture of polypeptides produced during the partial hydrolysis of proteins, typically by enzymes or acids. Proteoses are intermediate products between native proteins and simpler peptides or amino acids.
Usage Examples
- (Intermediate peptide fragments formed during protein breakdown.)
- (A technical distinction in protein chemistry.)
Advanced Usage
"Primary proteose": a specific fraction of proteose obtained early in protein hydrolysis.
- The primary proteose fraction was isolated after 30 minutes of digestion. (A distinct early-stage peptide mixture.)
"Proteose-peptone": a term sometimes used interchangeably, though proteoses are less degraded than peptones.
- The culture medium contained proteose-peptone to support bacterial growth. (A nutrient source in microbiology.)
Variants and Related Words
Proteolytic (adj): relating to the breakdown of proteins into proteoses and other fragments.
- Proteolytic enzymes catalyze the formation of proteoses. (Enzymes that digest proteins.)
Protease (n): an enzyme that breaks down proteins, producing proteoses among other products.
- Pancreatic protease generates proteoses during digestion. (A digestive enzyme.)
Synonyms
- Polypeptide mixture: a general term for a collection of peptide chains.
- Intermediate protein digest: a descriptive phrase for proteoses as a stage in protein hydrolysis.
