What else can I help you with?
Is tryptophan a polar molecule?
Yes, tryptophan is a polar molecule.
Is tryptophan a polar or nonpolar molecule?
Tryptophan is a polar molecule.
What is the relationship between tryptophan and UV absorbance?
Tryptophan is an amino acid that absorbs ultraviolet (UV) light. The relationship between tryptophan and UV absorbance is that tryptophan molecules can absorb UV light, which can be measured as a way to detect and quantify the presence of tryptophan in a sample.
What acts as a co-repressor to block transcription of the tryptophan operon?
The corepressor tryptophan itself binds to the repressor protein, causing a conformational change that allows it to bind to the operator sequence of the tryptophan operon. This blocks RNA polymerase from transcribing the operon, leading to repression of tryptophan biosynthesis.
Is tryptophan considered an acidic or basic compound?
Tryptophan is considered a basic compound.
What amino acid causes sleepiness following the consumption of a traditional Thanksgiving dinner?
Tryptophan
The ting yuo may want most after a Thanksgiving feast?
The two things many people want most after a Thanksgiving feast are looser clothes and a nap. It is thought that the desire for the nap is caused by the tryptophan in the turkey.
Does turkey have tryptophan in it?
Yes. Tryptophan is a protein common in many meat and dairy foods.Some people blame their postprandial (after eating) sleepiness on Thanksgiving on the tryptophan in the turkey. Well, blame something else! Tryptophan is common in MANY foods, and turkey is no more a culprit than chicken or cheese.
What is Tryptophan?
ANSWER:Imagine this. You eat a huge thanksgiving meal of turkey, dressing, cranberry sauce and the dessert of your choice. Now, what do you do? You get tired, grab the nearest couch and take a nap. Tryptophan is an ingredient in some foods that make you sleepy. It actually promotes deep sleep. (YAWN)

What is the chemical formula for tryptophan?
The chemical formula for tryptophan is C11H12N2O2
Is tryptophan a polar molecule?
Yes, tryptophan is a polar molecule.
Is tryptophan a polar or nonpolar molecule?
Tryptophan is a polar molecule.
What chemical grouping is responsible for a positive Hopkins-Cole test?
Tryptophan
The expression of the tryptophan operon is controlled by?
The expression of the tryptophan operon is controlled by a repressor protein that binds to the operator region in the presence of tryptophan. When tryptophan levels are high, the repressor is active and prevents transcription of the operon. When tryptophan levels are low, the repressor is inactive, allowing transcription to occur.
Why is the tryptophan operon turned off in the presence of tryptophan?
The tryptophan operon is turned off in the presence of tryptophan because tryptophan acts as a corepressor. When tryptophan levels are high, it binds to the trp repressor protein. This trp-repressor complex then binds to the operator region of the operon, preventing RNA polymerase from transcribing the genes involved in tryptophan synthesis.
The tryptophan operon is a repressible operon that is?
regulated by the availability of tryptophan. When tryptophan levels are high, tryptophan acts as a corepressor, binding to the repressor protein, which then binds to the operator, preventing gene transcription. This allows bacteria to conserve energy by only producing tryptophan when needed.
