What is remedy for urea?
urea is mixed with sterile water and is a remedy for adenocarcinoma cancer
How many units of nitrogen in 217 pounds of urea?
Assuming the urea has the normal grade of 46% nitrogen, it has a total of 100 pounds, or units, of nitrogen.
What is the atomic mass unit of urea?

What byproduct of protein catabolism constitutes approximately one half of all nitrogen waste?
creatinine
How many units is in 200 pounds of urea?
200 pounds = 200 pounds. Since no other unit is specified, we can assume that "pound" is the unit in this case.
Is enterococcus faecalis positive or negative with the urea broth test?
Enterococcus faecalis is urea-positive, meaning it can hydrolyze urea in the urea broth test. This ability to break down urea into ammonia and CO2 can be detected by a change in pH indicator in the broth from yellow to pink.
What bacteria is indole negative urea positive methyl red positive hydrogen sulfide positive and lactose negative?
Proteus vulgaris is a bacterium that fits this description. It is indole negative, urea positive, methyl red positive, hydrogen sulfide positive, and lactose negative. These characteristics are used in biochemical tests to help classify and identify different bacteria species.
Is streptococcus salivarius positive for urease?
Yes, Streptococcus salivarius is typically negative for the enzyme urease, which is responsible for breaking down urea into ammonia and carbon dioxide.
Will enterobacter cloacae use urea?
Yes, Enterobacter cloacae can utilize urea as a nitrogen source for growth. Urea can be broken down by the enzyme urease into ammonia and carbon dioxide, which the bacterium can then use for various metabolic processes.
Is staphylococcus aureus urea slant positive?
It's possible that it can be.
Why is it acceptable to record a positive result before the suggested incubation timne is completed but it is not acceptable to record a negative result early when doing a urea hydrolysis test?
Recording a positive result early is acceptable because some reactions may show positive results before the incubation time is completed due to accelerated enzyme activity. However, recording a negative result early for a urea hydrolysis test is not recommended because the reaction may need the full incubation period for urease activity to fully hydrolyze the urea and produce the correct result. This premature recording of a negative result may lead to inaccurate conclusions.
What does a positive test result for urea hydrolysis look like?
Bright pinkish-red.
What does urine contain?
Urine is a mixture contained of fluids throughout your intestines and functioning bladder. these are water, keratin, urea, positive hydrogen...
What is proteus mirabilis results for urea test?
Proteus mirabilis is positive for the urea test, meaning it can hydrolyze urea, producing ammonia and raising the pH of the medium, causing a color change. This is due to the presence of the enzyme urease in Proteus mirabilis.
Why is ammonium chloride soluble in water?
It is highly water soluble (hydrophillic) related to it's polarity. It is a polar molecule, meaning it has a partial negative and a partial positive side, and therefore the negative portion of ammonia (Nitrogen) would attract the positive portion of of water (hydrogen), and the positive portion of ammonia (hydrogen) would attract the negative portion of water (oxygen).
Why urea and sugar are polar?
Urea and sugar are polar molecules because they contain polar covalent bonds due to differences in electronegativity between the atoms involved. This creates regions of partial positive and negative charges within the molecules, making them polar. This polarity allows them to readily interact with water and other polar substances.
Is proteus urease positive?
Proteus urease is considered a positive organisim. This occurs when enterics hydrolyze urea and cause a rapid deterioation. This term is also referred to as rapid urease positive organisms.
