Other Algae

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Overview of Algae

The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...

Red Algae

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

Green Algae01:21

Green Algae

883
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

Overview of the Cardiovascular System

The cardiovascular system is a vital transportation system in the body. It comprises the heart and blood vessels and facilitates the exchange of gases, nutrients, and waste products.
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.

  • Marine natural products chemistry
  • Pharmacology
  • Biochemistry

Background:

  • Marine algae are a rich source of bioactive compounds.
  • Nitric oxide plays a crucial role in cardiovascular health.
  • Understanding the interaction of marine compounds with nitric oxide is key to discovering new therapeutics.

Purpose of the Study:

  • To investigate the interaction of bioactive compounds from marine algae with nitric/nitrous acid.

  • To explore potential nitric oxide carrier properties of algal compounds.

Main Methods:

  • Ethanolic extracts of marine algae were separated using chromatographic plates.
  • UV absorption spectra were used for characterization before and after reaction with nitric acid.
  • Colorimetric reactions after derivatization with anisaldehyde were employed.

Main Results:

  • Diterpenes from Dictyota dichotoma and sterols from Caulerpa brachypus were found to bind nitric oxide.
  • These compounds may function as nitric oxide carriers.
  • Fucoxanthin, a carotenoid in brown algae, also binds nitric oxide, but with stronger bonds.

Conclusions:

  • Certain marine algae compounds, specifically diterpenes and sterols, show potential as nitric oxide carriers.
  • Further research is needed to evaluate the cardiovascular benefits of these compounds.
  • The reported method is useful for screening algae species for cardiovascular activity.
