Abstract: A method for the enzymatically catalyzed synthesis of a diol from an amino acid includes enzymatically hydroxylating the amino acid, enzymatically deaminating the amino acid, the deamination resulting in the formation of an oxo group at the position of the amino group, enzymatically decarboxylating the amino acid, and enzymatically hydrogenating the oxo group resulting from the deamination reaction.

Abstract: The invention is partly based on the unexpected discoveries of cellular differences in response to pH alterations, and a key role of the cells' proliferative statuses in determining their responses. Thus, pH modifiers, their doses and dosing regimens are chosen to selectively deplete and/or suppress inflammatory and/or non-inflammatory pathological cells and their proliferation while preserving normal cells in diseases whose pathogenesis is partially or fully attributable to inflammation and/or cell proliferation. Conversely, pH modifiers, their doses and dosing regimens were chosen to selectively increase the population and/or proliferation of normal cells to promote protective immune and inflammatory responses, normal cell regeneration or renewal.
