There are two types of kefir: water kefir and milk kefir. Both kefir grains contain live microorganisms and are sustainable and economical. With little care, these grains can be recycled over and over again.
Since coenzyme A is, in chemical terms, a thiol, it can react with carboxylic acids to form thioesters, thus functioning as an acyl group carrier. It assists in transferring fatty acids from the cytoplasm to mitochondria.A molecule of coenzyme A carrying an acetyl group is also referred to as acetyl-CoA.oenzyme A is also the source of the phosphopantetheine group that is added as a prosthetic group to proteins such as acyl carrier protein and formyltetrahydrofolate dehydrogenase.
1 All three compounds are efficiently converted in the body to the coenzyme form of vitamin B6, pyridoxal phosphate (PALP) 3. 2  This conversion is catalyzed by the ATP requiring enzyme, pyridoxal kinase. 3  Coenzyme form of Vit-B6: Pyridoxal Phosphate 5. The reduced forms of FMN and FAD are formed, FMNH2 and FADH2, respectively. 2  3. Structure of FAD Nitrogens 1 & 5 carry hydrogens in FADH2 Coenzyme Function: 1. Riboflavin acts as an integral component of two coenzymes: FAD (flavin adenine dinucleotide) and FMN (flavin mononucleotide).
