humor us to compare vitamin E and vitamin B six. Figure out which one is more water soluble nutrients towards fatso. You'll recall that the rule for the salt ability is that like this office like So if you have a non polar song like that, fat is non polar, then it's going to go with a non polar solvent. But if you have a water something well, sorry if you have a polar, Saul, you make water. Water's polar. You expected to dissolve with Paul polar salutes. So basically, we're looking for which ones of these is polar? One easy way to do this is to look for polar groups in the structure. So whenever you see things like ohh the's all these oxygen groups of this foster, is this really really Electra Negative group all of these air polar groups that are part of this molecule. So vitamin B six, because there's all these polar groups would dissolve in would be water soluble, whereas in vitamin E, what you see is this long carbon chain so that each of these weird disease we have a carbon atom and whenever we have carbon hydrogen atoms like these guns are non polar. So really, all we have going here, miss, it's one little oxygen that provides a little bit of polarity to vitamin E. But for the most part, we have. And I guess we also have this 10 age group. But for the most part, we have all these carbonates that are non polar and thus vitamin D would be more fat soluble then, um what?
