▎ NAD＋ Noiʻi
He aha ka NAD+?
ʻO NAD + (Nicotinamide Adenine Dinucleotide) kahi coenzyme koʻikoʻi i loaʻa i nā mea ola. Hoʻokumu ʻia ia e ka pilina o adenosine ribonucleotide a me nicotinamide ribonucleotide ma o kahi hui phosphate. Ma ke ʻano he coenzyme koʻikoʻi i nā hopena redox, he kuleana koʻikoʻi ka NAD + i ka metabolism cellular. Hiki iā ia ke hoʻololi ma waena o ka moku'āina oxidized (NAD +) a me ka moku'āina i hoʻemi ʻia (NADH), e komo ana i nā kaʻina metabolism ikehu e like me ka glycolysis, ka citric acid cycle, a me ka phosphorylation oxidative, e kōkua ana i nā cell e hoʻololi i ka meaʻai i ka ikehu (ATP). Eia kekahi, lawelawe ʻo NAD + ma ke ʻano he cofactor pono no nā enzymes like ʻole (e like me PARP a me Sirtuins), e komo ana i nā kaʻina hana e pili ana i ka hoʻoponopono DNA, ka hōʻailona cell, a me ka anti-aging.
He aha ke kumu noiʻi o NAD +?
Cofactor koʻikoʻi i nā hana he nui:
ʻO NAD + kahi cofactor koʻikoʻi i nā hopena redox he nui (Shats I, 2020). I loko o nā pūnaewele, ua komo i loko o nā kaʻina cellular he nui e like me ka metabolism ikehu, ke kūpaʻa genomic, a me ka pane immune. No ka laʻana, i ka metabolism ikehu, hana ʻo NAD + ma ke ʻano he mea lawe electron i nā kaʻina e like me ka glycolysis a me ka tricarboxylic acid cycle, e komo ana i nā hopena redox e hoʻololi i ka ikehu kemika i loko o nā meaʻai e like me ka glucose i kahi ʻano ikehu e hiki ai i nā cell ke hoʻohana.
Ka pilina me nā Enzymes Nui:
