Is there role of vitamin C in cholesterol metabolism?

[@Rajesh_Jambhulkar]

No direct involvement in pathway.
Indirectly involved in regulation.
Dietary inadequacy of vit C is associated indirectly with a lowering of cholesterol absorption.
Vit C has direct involvement in steroid hormones synthesis via hydroxylation reactions

[@pratikchauhan6377]

These informations already available in Textbooks.
Try to make videos on Real-time problem solving matters.
Like How you can prevent Ascorbic acid oxidation in commercial products?

I take vitamin c 500mg tab per day good or bad

[@ivmgg2658]

Hey,thanks for the explanation,i got a question doe i am a mercury and lead toxic person,i read that taking big doses of AA daily can make your body start flushing out the heavy metals
What i wanted to know is wouldnt drinking like 10 grams of AA every day (with equal intervals between doses) wouldnt this acidify my body and promote other illnesses?
Thanks and have a good day!

[@Rajesh_Jambhulkar]

AA is water soluble. Will be excreted in urine if taken in excess. RDA is only 75mg.

[@clipssnap5806]

Nice

[@AbhijeetArchives]

Thank you sir
Superb video and superb mnemonic 🌟 🌟 🌟
I have a doubt,
In Satyanarayana, pg. 137, the rda of vit c is 40 to 50 mg....
Which one is right?

[@Rajesh_Jambhulkar]

Most of the time numerical values are different in different Textbook
60 to 75 mg/day
Vasudevan Biochemistry

[@prachisinghkashyap8471]

In vasudevan it is 75mg /day = 50ml of pure orange juice
