Secondary Metabolites

2020
Secondary metabolites are organic compounds produced by microorganism or plant which are not directly involved in the growth, development, or reproduction of the organism. Secondary metabolites play an important role in plant defense against insects and microorganisms defenses. Humans use to secondary metabolites in medicines, flavorings, pigments, and

Extraction of Plant Secondary Metabolites

2006
This chapter presents an overview of the preparation of extracts from plants using organic solvents, with emphasis on common problems encountered and methods for their reduction or elimination. In addition to generally applicable extraction protocols, methods are suggested for selectively extracting specific classes of plant-derived compounds, and ...

Redox active secondary metabolites

Current Opinion in Chemical Biology, 2011
Various secondary metabolites from plants, bacteria and fungi are redox active and able to modulate the intracellular redox equilibrium in living cells. Many of these compounds behave as antioxidants, yet some of them also cause oxidative modifications, which may ultimately result in cell death.

Unexpected applications of secondary metabolites

Biotechnology Advances, 2011
Secondary metabolites have been found to have interesting applications over and above their well-known medical uses, e.g., as antimicrobials, etc. These alternative applications include antitumor, cholesterol-lowering, immunosuppressant, antiprotozoal, antihelminth, antiviral and anti-ageing activities.

Production of Secondary Metabolites by Bioconversion

2007
The omnipotency (omnis = all, potens = powerful) of the plant cell implies that all genetic information present in the plant is principally available in each cell. This means that genes encoding enzymes that belong to biosynthetic pathways can be brought to expression.

The physiology and biosynthesis of secondary metabolites

Acta Biologica Hungarica, 1997
Recently, several excellent reviews appeared /9, 12, 15, 29/ summarizing new findings of the last years and describing the topic in the new interconnections. The signalling systems through which changes in environmental conditions affecting the growth of microorganism are sensed, transmitted and converted into mechanisms controlling the production of ...

Mutation and the Production of Secondary Metabolites

1973
Publisher Summary This chapter deals with microbially produced secondary metabolites. Secondary metabolites are a group of products that are extremely important to health and nutrition. They are usually produced during the idiophase of development, have no general function in growth processes, are produced by certain restricted taxonomic groups of ...

Secondary metabolites for antiulcer activity

Natural Product Research, 2015
Peptic ulcers are open sores or erosions in the lining of either the duodenum (duodenal ulcers) or the stomach (gastric ulcers). Peptic ulcer, which is mainly caused by bacterial attack or excess of acid secretion, can be cured effectively by these isolated plant compounds.

Secondary Metabolite Components of Kiwifruit

2013
Both green and gold kiwifruit contain high concentrations of vitamin C, and much of the "health story" of kiwifruit involves this vitamin. Kiwifruit also contain other compounds that are bioactive and beneficial to health. In this chapter, the secondary metabolite composition of kiwifruit is presented.
