What is the wavelenght to measure GTP, ATP, CTP, TTP, UTP, and peptide bond? \n\nThanks very much

The wavelength of absorbance for a peptide bond is 190-230nm.\n\nRetrieved from "http://en.wikipedia.org/wiki/Peptide_bond"\n\nI couldn't find any info on the other compounds - sorry!

Its resolving power is around 2 nanometers (two millionths of a millimeter).\nIt can detect proteins and other small molecules. \nBut atoms are much smaller than that, and can only be visualized by atomic force and tunnel effect microscopes, which use a very fine tip to probe surfaces, and react electrically to the atoms they encounter. But they don´t actually render real images, but instead an artificial computer-based reconstitution.

Hmm, you're right, the methods section of that paper is not very clear.  Anyway, check out the ref below.  Look midway through the 4th paragraph under Results, titled "Effect of recombinant Acrp30 infusion on hepatic glucose fluxes."  There could be other methods, but this is what I found.  Good luck.

well i didnt get your question properly but i will try to make the concept clear....actually adenine and guanine(called purines), thymine and cytosine (pyridines)....so adenine is attach to thymine with the help of "3 HYDROGEN BOND"  and guanine is attach to cytosine with the help of "2 HYDROGEN BOND"....so its natural that the amount of adenine is equal to amount of thymine and amount of guanine is equal to amount of cytosine...\nso lets take an example suppose u have .20 of adenine and then it is must that thymine should also be .20......similarrly if u have .30 of gunaine then it is must that u have .30 of cytosine.

I know that ATP is "made" into ADP in the muscles during the latent stage when the myosin heads detach from the actin though as for what catalyzes the rest i don't know, I realy didn't know the anwer any way , just trying to sound like i know what i'm talking about , but i'm interested to know let me know if you want I took A&P 102 this semester and seemed to forgot.

i think that if you categorise it  under physics/biology/chemistry, you might get a better response.\n\nnevertheless:\n\nhttp://school.discovery.com/homeworkhelp/bjpinchbeck/bjscience.html

you determine the hybridization of a particular atom by seeing how many electron pairs there are around a particular atom.  For example, if you draw the structure for ethylene (C2H4) you get \n\nH3C=CH3\n\nthis means that there are 3 electron pairs around both C atoms and they are both show sp2 hybridization.  \n\nIn another example, d2sp3 hybridization, you will have 6 electron pairs around the d2sp3 hybridized atom.  \nIn dsp3 hybridization, you will have 5\nin sp3 hybridization, you will have 4, etc...

Molecular bonding.\n\nThis is a function of the atomic weight (protons in the nuclei) and the distrobution of the electron shell.  Give me three years and I will explain it fully.

I am not a chemistry student but I make this research for you and maybe it helps you http://www.chem.latech.edu/~deddy/chem104/104Antacid.htm\nhttp://www.chemcool.com/regents/acidsbasessalts/aim3.htm\n\njust copy those links and you should be on your way to solve ur problem.

got a dandy.....even though  it  seems  difficult   youll  break through  and  find  out  you can  almost  measure  anything....try  this  because  i dont  know  what  type  of  equipment  you have....in  search  bar  go.....vernier  read .. hit search..the  NTNU site java  is  excellentyou you can  even  practice  measuring  on  line.....reading  a  vernier  is  good too.....check  them  all

I use a 1 KB DNA ladder for electrophoresis and it comes with a paper to actually tell you which band represents which size fragment. Maybe you could look on the tech company's website. If you do not need to know the actual fragment size of each band, maybe you could just compare to make sure the band you need is there in the first place.

Well, I'll start you off.\n\nAbsorbances are additive, so you subtract the blank from the measurement (.214 - .009 = .205)\n\nSo the absorbance is .205. Now you use beer's law, which is:\n\nA = ebc\n\ne is molar absorptivity (in L/mol cm)\nb is path length (cm)\nc is concentration. \n\nYou use that equation to figure out the concentration of the complex.\n\nFrom there, you can figure out the concentration of iodine based on the amount of starch used. Unfortunately, you've not provided enough information to go beyond here.
