Why is it that we need carbohydrates?
From glycolysis we get pyruvate, which is turned into Acetyl-CoA to be used in the krebs cycle. However, we also get loads of Acetyl-CoA from beta-oxidation. So why is it that we need glucose to fuel the krebs cycle?
Or rather, what are the end products mediated by glycolysis that we can't get from beta-oxidation?
>Why is it that we need carbohydrates?
We don't. Carbohydrates are not essential.
Bump for interest.
Pentoses you dumb fucc

Not OP, can you give me a brief summary of what I should know about that?
Aside from being the carbon skeleton needed to make lipids and many amino acids, they are a very rapid source of energy. Particularly in glycolysis. They're also needed for nucleosides. Your brain also exists solely on glucose.

Everything can be answered in this video OP:

we don't NEED glucose
you can survive on a nearly pure protein diet just fine. there's plenty of predators in the world that do just that.
carbohydrates are just super fucking common since they're easy to make and plants make a fuckton of them

We basically need glucose to synthesize pentoses, which we need for synthesizing ATP, RNA, DNA and some other shit

Awesome, thanks bro
Because your cells need energy and carbs are the common energy source found in nature. Did you fail biochem 101?

I thought OP was asking "why does life need carbohydrates"
