Alkaloids: Their Importance in Nature and for Human Life

by Joanna Kurek

Introduction

In nature there are many natural compounds. From among many classes of naturally occurring organic compounds such as carbohydrates, lipids, proteins, amino acids, anthocyanins, flavonoids, and steroids, the one that seems to be quite special is alkaloids. What makes them special? They derived from amino acids and can be synthetized as secondary metabolites by plants and some animals. These compounds play an important role in living organisms.

Flavonoids: An Overview

by Panche, A. N., Diwan, A. D., & Chandra, S. R.

Part 1: Abstract and Introduction

Abstract
Flavonoids, a group of natural substances with variable phenolic structures, are found in fruits, vegetables, grains, bark, roots, stems, flowers, tea and wine. These natural products are well known for their beneficial effects on health and efforts are being made to isolate the ingredients so called flavonoids. Flavonoids are now considered as an indispensable component in a variety of nutraceutical, pharmaceutical, medicinal and cosmetic applications. This is attributed to their anti-oxidative, anti-inflammatory, anti-mutagenic and anti-carcinogenic properties coupled with their capacity to modulate key cellular enzyme function. Research on flavonoids received an added impulse with the discovery of the low cardiovascular mortality rate and also prevention of CHD.

Product Review: The Various Health Benefits of Omega-3 Fatty Acids

In investigating the nutraceutical properties of fishes in the month of March, we discovered a highly important group of fatty acids called the Omega-3 fatty acids. Omega-3 fatty acids (OM3FAs or n-3 PUFAs) are unsaturated fatty acids, and currently, the three most clinically relevant types are ?-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Oils containing these fatty acids originate in plant sources and can be found in fish, fish products, seeds, nuts, green leafy vegetables, and beans.
