Bioremediation00:46

Bioremediation

19.7K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Biosynthesis of Lipids01:29

Biosynthesis of Lipids

59
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...

Esters to Carboxylic Acids: Saponification01:25

Esters to Carboxylic Acids: Saponification

4.6K
Esters can be hydrolyzed to carboxylic acids under acidic or basic conditions. Base-promoted hydrolysis of esters is a nucleophilic acyl substitution reaction in which esters react with an aqueous base, followed by an acid to give carboxylic acids. This reaction is also known as saponification because it forms the basis for making soaps from fats.
The reaction requires a base in stoichiometric amounts, which participates in the reaction and is not regenerated later. So, the base acts as a...

Olefin Metathesis Polymerization: Overview01:13

Olefin Metathesis Polymerization: Overview

2.2K
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
Ruthenium-based Grubbs catalyst is the most commonly used catalyst for olefin metathesis polymerization. Grubbs catalyst consists...

Esters to β-Ketoesters: Claisen Condensation Overview01:24

Esters to β-Ketoesters: Claisen Condensation Overview

3.4K
Regular Claisen condensation is a base-promoted reaction involving identical esters with two α hydrogens, condensing to produce β-ketoesters. It is a nucleophilic acyl substitution reaction wherein one of the ester molecules, upon deprotonation by the base, forms a nucleophilic enolate ion, while the other molecule serves as an electrophile.

Biomass Energy01:30

Biomass Energy

Biomass EnergyBiomass energy is a renewable energy source derived from organic materials such as plants, wood, and animal waste. These materials store energy from the sun through photosynthesis and can be used to produce heat, electricity, and biofuels. Biomass is a sustainable alternative to fossil fuels, helping to reduce greenhouse gas emissions.Importance of Biomass EnergyRenewable and Sustainable – Biomass comes from plants and waste materials, making it a continuously available energy...
