Biosynthesis of Lipids

Biosynthesis of Lipids

Microbial membranes exhibit remarkable diversity in lipid composition, reflecting evolutionary adaptations to various environmental conditions. The three domains of life—Bacteria, Archaea, and Eukarya—synthesize membrane lipids through distinct biosynthetic pathways, leading to fundamental structural differences that impact membrane stability, function, and adaptability.Fatty Acid-Based Lipids in Bacteria and EukaryaBacteria and eukaryotes share a common fatty acid biosynthesis...

Lipid Catabolism

Lipid Catabolism

Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...

Green Algae

Green Algae

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...

Red Algae

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...

Lipid-derived Compounds in the Human Body

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Overview of Algae

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...

Area of Science:

Marine Biology
Biochemistry
Lipidomics

Background:

Microalgae are primary aquatic food sources and synthesize valuable compounds like polyunsaturated fatty acids (PUFAs).
Oxidative degradation of PUFAs produces oxylipins, known for their bioactive properties and potential health benefits.

Purpose of the Study:

To profile and quantify oxylipins in five different microalgae species.
To investigate the diversity and concentration of enzymatic and non-enzymatic oxylipins.

Main Methods:

Cultivation of five microalgae species in 10-L photo-bioreactors under optimal conditions.
Extraction and analysis of microalgae samples using Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS).

Main Results:

Identification of up to 33 non-enzymatic and 24 enzymatic oxylipins across the five species.
Significant diversity in oxylipin profiles and concentrations among the studied microalgae.

Conclusions:

Marine microalgae are a promising source of diverse bioactive oxylipins.
These oxylipins may play a role in preventive health, offering antioxidant, anti-inflammatory, neuroprotective, immunomodulatory, and cardiovascular benefits.
