Protein engineering of oxidoreductases utilizing nicotinamide-based coenzymes, with applications in synthetic biology

open access: yesSynthetic and Systems Biotechnology, 2017
Two natural nicotinamide-based coenzymes (NAD and NADP) are indispensably required by the vast majority of oxidoreductases for catabolism and anabolism, respectively.

Testing the content of vitamin A in dietary supplements

open access: yesJournal of Education, Health and Sport, 2019
Vitamins in the human body perform regulatory functions, determine the development, health and physical performance of the body. Most of them are not synthesised in the body, therefore they must be supplied with food. They interact with enzymes, which is

Atherosclerosis and Coenzyme Q10 [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Atherosclerosis is the most common cause of cardiac deaths worldwide. Classically, atherosclerosis has been explained as a simple arterial lipid deposition with concomitant loss of vascular elasticity. Eventually, this condition can lead to consequent blood flow reduction through the affected vessel.
