Sentence examples for metabolism cannot be from inspiring English sources

Retinoids are also known to be significantly metabolized by CYP26, though the contribution of this metabolism cannot be determined by the same methods as for the other CYPs investigated, as supersomes over-expressing CYP26 are not currently available.

In this work, we have found that whereas the loss of the regulatory functions of CMA in liver, such as those involved in the control of carbohydrate and lipid metabolism, cannot be compensated for – leading to overt metabolic phenotypes upon CMA failure –, the contribution of CMA to quality control in young mice can be effectively handled by other proteolytic systems.

Whereas some scientists fervently advocate that viruses should have a place in the tree of life [ 9], many other consider that, being acellular and lacking any kind of carbon and energy metabolism, viruses cannot be properly compared with true living beings (i.e. cellular) and, therefore, do not belong to the tree of life [ 7, 10].
