Triterpene Structural Diversification by Plant Cytochrome P450 Enzymes

Frontiers in Plant Science, 2017
Cytochrome P450 monooxygenases (P450s) represent the largest enzyme family of the plant metabolism. Plants typically devote about 1% of the protein-coding genes for the P450s to execute primary metabolism and also to perform species-specific specialized ...

Immunomodulatory properties of triterpenes [PDF]

Phytochemistry Reviews, 2021
The immune system is one of the main defence mechanisms of the human body. Inadequacy of this system or immunodeficiency results in increased risk of infections and tumours, whereas over-activation of the immune system causes allergic or autoimmune disorders.

Steroidal Triterpenes of Cholesterol Synthesis [PDF]

Molecules, 2013
Cholesterol synthesis is a ubiquitous and housekeeping metabolic pathway that leads to cholesterol, an essential structural component of mammalian cell membranes, required for proper membrane permeability and fluidity. The last part of the pathway involves steroidal triterpenes with cholestane ring structures.
