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 else can I help you with?
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.
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 is the relationship of tryptophan to niacin?
The body uses tryptophan to create niacin.
Which foods contain tryptophan?
There is a lot of foods that contain Tryptophan. Any meat and food from animals more than likely has Tryptophan in it. Also lots of plants such as seaweed and spinach have Tryptophan. Soy foods also contain Tryptophan. For a more complete list of foods that contain Tryptophan visit the website in the related links section below.
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.
What has more tryptophan ham or turkey?
Ham has more tryptophan than turkey.
