You should go for Ph. D. in Organic Chemistry. It is not true that jobs are not vailable. Even outside the academic institutes you have plenty of jobs in ...
I'd just add, don't worry about post-docing yet. You've got plenty of time and plenty of stuff might happen. You might not like it, you might get interested in...
I just want to straighten this out if you don't mind? Someone else told me that it isn't the N, O, or S atoms, but electronegative forces. Is it not the N, O...
... atoms, ... I understand your confusion. The idea of "electronegativity" is a bit strange, but is very important in organic chemistry. "Electrongeativity"...
Hi, I just wanted to ask a question in regards to the discussion you were having about hydrogen bonds; I actually wanted to know about covalent bonds. (Only...
... you ... Be careful here. A hydrogen is *not* a real chemical bond. They probably should be called "hydrogen attractions" because that's all they really...
Could someone refresh my memory on how they determined Avogadro's number? I know that it's 6.023 x 10^23, but I can't remember how this was determined. Thanks,...
... this ... It was done experimentally. I am not sure but it may have been determined from radioactive decay or from crystal structure. I have looked in one...
Gregg- Thanks for explaining that for me. But with covalent bonds I understand that it is sharing a pair of electrons. For protein folding, what electrons...
... Let's try this from the start. A protein is a long string of amino acids. All these amino acids are held together by covalent bonds. The order in which the...
Hi Jumping in this conversation how do you determine electromagnetic positive and negative and how do you determine each. The question is relative to...
Pamela, I'm not sure what you mean by "identification of a single current found in the Earth but unproven." In the discussion of hydrogen bonds were talking...
Hi, I also would like to jump in and ask a question about covalent bonds. Are covalent bonds already there before folding, and they automatically come with...
... The covalent bonds in the proteins we were discussing are the bonds that hold the atoms together in the amino acids. Except for some pretty rare cases, all...
Does potassium ions for example and any other ions for that matter in the cell surrounding water molecules have any effect on any of the bonds, namely, salt...
Anna, You'll have to be more specific in your question, becuase it's not clear to me what you're asking. Are you asking about the effect of potassium ions on...
Hi, I am sorry I should have been more specific. I meant the cell in which the folding will take place if the potassium ions or any other kind of ion for that...
... in ... other ... This is getting a little specialized for me. You should probably ask an honest-to-goodness biochemist. I know that the additions of...
