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.
Nicotinamide adenine dinucleotide, abbreviated NAD+, is a coenzyme found in all living cells. The compound is a dinucleotide, since it consists of two nucleotides joined throu â¦ gh their phosphate groups, with one nucleotide containing an adenine base and the other containing nicotinamide. Coenzymes are small organic non-protein molecules that carry chemical groups between enzymes.[1] Coenzymes are sometimes referred to as cosubstrates. These molecules are â¦ substrates for enzymes and do not form a permanent part of the enzymes' structures.
