Question

what does (H-) opposite of a proton

Answer 1

i am trying to resolve the glycolysis step where NAD is reduced to NADH, there is an investment of H- if you will and hence an additional product of H+, someone please explain what H- really means, thanks:)

Answer 2

Wow, it's been a while since I've done metabolic biochemie. But H- is the hydride anion. I think the hydride ion acts as a nucleophile, since the only part that undergoes any chemistry on NAD+ is the top portion of it. I think the nitrogenous base part? Let me post a photo of NAD+

Answer 3

In which case, H- is the reducing agent in this reaction. The electrons on the hydride ion go to nicotinamide adenosine dinucleotide

Answer 4

Thank you very much, that was quite helpful, and yes its the about the 6th step in Glycolysis...:)
