tryptophane
Definition
Noun 1. An essential amino acid: Tryptophane (also spelled tryptophan) is one of the twenty standard amino acids that are the building blocks of proteins in living organisms. It is classified as "essential" because the human body cannot synthesize it; it must be obtained from the diet.
Usage
Tryptophane is used in scientific, nutritional, and biochemical contexts to refer to this specific biochemical compound. * Tryptophane is a precursor for the synthesis of the neurotransmitter serotonin. * Foods like turkey, eggs, and cheese are good dietary sources of tryptophane. * The researcher studied the role of tryptophane in protein folding.
Advanced Usage
- Biochemical Pathway: Tryptophane is a metabolic precursor not only to serotonin but also to the vitamin niacin (vitamin B3) and the hormone melatonin.
- A deficiency in tryptophane can lead to reduced niacin synthesis.
- Scientific Notation: In biochemistry, it is often abbreviated as Trp or W (its one-letter code).
Variants and Related Words
- Tryptophan: The more common modern spelling of the same amino acid.
- L-tryptophan: The specific, naturally occurring form (stereoisomer) found in proteins.
- 5-HTP (5-Hydroxytryptophan): A direct chemical derivative of tryptophane and a precursor in serotonin synthesis.
Synonyms
- Essential amino acid (this describes its class, not a direct synonym).
- Proteinogenic amino acid (an amino acid used in protein biosynthesis).
Related Phrases/Concepts
- Tryptophane operon: A group of genes involved in the biosynthesis of tryptophane in bacteria, a classic model in genetics for understanding gene regulation.
- Tryptophane deficiency: A state of inadequate intake or absorption, which can impact protein synthesis, mood, and sleep regulation.
Noun
-
an amino acid that occurs in proteins; is essential for growth and normal metabolism; a precursor of niacin
