whats the molecular weight of Ganglioside type III from bovine brain?
967510
Type III Galglioside is a mixture: 20% sialic acid, then equimolar amounts of GM1 and GD1a gangliosides.\n\nA common sialic acid is N-acetylneuraminic acid, with a molecular weight of 310 Da\nGM1 is 49 000 Da\nGD1a is 63 000 Da\n\n1/2 mol each of GD1a and GM1 would weigh 112000 g, meaning it would have a corresponding mass of 28000 g of sialic acid, which is 28000 g/310 g/mol = 90.32 mol\n\nThe mole fractions are therefore 90.32/91.32 = 98.9% for the sialic acid, and 0.5/91.32 = 0.5475% for the 2 gangliosides.\n\nThat makes the average molecular weight equal to 0.989*310 Da + 0.005475 (49000 Da + 63000 Da) = 919.79 Da\n\nThe average molecular weight of the gangliosides, not including the acid, is 56 kDa.

You were close by looking at wikipedia. The image is a ball and stick but you could figure it out. The description says it is just fatty acids (usually alkyl C16-C18) chains attached by an ester bond to the hydroxyls of a sucrose molecule (8 fatty acids).

There is a simple approximation that the average molecular mass for a base pair is 660. That means that a mole of a base bair would be 660 g or if you prefer 6.023*10^23 base pairs would be 660*10^9 ng.\n\nTherefore 1 ng would be (6.023*10^23)/(660*10^9) =9.13*10^11 base pairs. I am using base pairs since DNA is double stranded. (If you wanted to take into account the nucleotides of both strands then you just mutliply by 2 (18.26*10^11))\n\nFor calculating the mass of the DNA, if bp is the number of basepairs of the genome of interest then its approximate molecular weight is 660*bp and the mass is \nmass=mole*MW = mole*660*bp\n\nFrom here on it depends on how many moles of DNA you have. If you want to find out the weight of a single molecule it is MW/6.023*10^23= 660*bp/6.023*10^23 g= 660*bp/6.023*10^14 ng

I can not find any sources on the composition, but regarding your second question:\nA complex sugar is a polysaccharide (that is 100% right).  It is definitely not a mono or disaccharide.

Check out the buffer recipe calculator at <http://www.bioinformatics.org/JaMBW//5/4/index.html>\n\nSome things to consider:\n\nAt what temperature do you want the pH to be 7.5? (the pKa of tris-base varies as a function of T)\n\nWhat ionic strength do you need?

the result is that ur left with 2 monosacharides
