AI Thread Summary
The molecular formula of galactose is C6H12O6. When linking 8 galactose molecules through dehydration synthesis, the expected new molecular formula is calculated as C48H80O40. The process involves subtracting water molecules, which consist of 2 hydrogen atoms and 1 oxygen atom for each bond formed. Therefore, for 8 galactose molecules, 7 water molecules are removed, resulting in a total subtraction of 14 hydrogens and 7 oxygens. The correct formula after accounting for these changes is C48H80O40, not C48H80H40, indicating a misunderstanding of the dehydration synthesis process and the resulting molecular formula.

The molecular formula of galactose is C6H12O6

If 8 galactose molecues were linked together by dehydration synthesis, the new molecular formula wil be C48H80H40 right?

did i do my math wrong?

Dehydration synthesis is just the loss of water , so a total of 16 Hydrogens and 8 Oxygens will be subtracted from the total molecular formula for 8 * (C6H12O6) which is C48H80H40

or am i missing a key concept here?

thanks

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
