Methyl cellulose

Methyl cellulose (or methylcellulose) is a compound derived from cellulose. It is sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a bulk-forming laxative. Like cellulose, it is not digestible, non-toxic, and not an allergen. In 2020, it was the 422nd most commonly prescribed medication in the United States, with more than 100 thousand prescriptions. Methyl cellulose has a wide range of uses. Methyl cellulose is used to treat constipation. Effects generally occur within three days. It is taken by mouth and is recommended with sufficient water. Side effects may include abdominal pain. It is classified as a bulk forming laxative. It works by increasing the amount of stool present which improves intestinal contractions. It is available over the counter. It is sold under the brand name Citrucel among others. The lubricating property of methylcellulose is of particular benefit in the treatment of dry eyes. Solutions containing methyl cellulose or similar cellulose derivatives are used as substitute for tears or saliva if the natural production of these fluids is disturbed. Methyl cellulose is used in the manufacture of drug capsules; its edible and nontoxic properties provide a vegetarian alternative to the use of gelatin. Methyl cellulose is occasionally added to hair shampoos, tooth pastes and liquid soaps, to generate their characteristic thick consistency. This is also done for foods, for example ice cream or croquette. Methyl cellulose is also an important emulsifier, preventing the separation of two mixed liquids because it is an emulsion stabilizer. The E number of methyl cellulose as food additive is E461. E464 is hydroxypropyl methylcellulose and more soluble in water. Methyl cellulose, as a gel, has the unique property of setting when hot and melting when cold. In some meat analogues that are intended to replicate the texture of meat, methyl cellulose is used as an ingredient, typically in concentrations less than 2%.

Glucuronoyl Esterases: Key Players for Carbohydrate and Lignin Valorization

Glucuronoyl esterases (GEs) are enzymes capable of cleaving ester linkages between lignin and hemicellulose. This study investigates the role of GEs in the conversion of lignocellulosic biomass and how these enzymes promote the disassembly of lignocellulose by breaking some of the covalent bonds between lignin and xylan within plant cell walls. By cleaving the ester-linked lignin-carbohydrate complexes (LCCs), we demonstrate the synergistic potential of GEs in combination with a GH10 endo-xylanase and a min

Position-specific carbon isotope analysis of glucose and tree-ring cellulose by Orbitrap mass spectrometry

The isotopic compositions of environmentally relevant compounds like glucose and cellulose carry traces of the metabolic processes they have undergone. However, many of the relevant fractionations are imparted at specific atomic positions, whereas most traditional isotope analyses measure the average isotopic composition of the whole molecule. Here, we present the first method for position-specific isotope analysis (PSIA) of glucose and cellulose via Electrospray-Ionization (ESI)-Orbitrap mass spectrometry.

Economic and environmental potential of a lignin-first biorefinery producing chemicals and bioplastics

Biomass is a promising feedstock to source renewable carbon needed to produce biobased chemicals and materials. Lignocellulosic biorefineries, however, can only be economically viable when all three major biomass components (lignin, cellulose, and hemicellulose) are valorised. Current extraction processes lead to the irreversible degradation of the lignin polymer. Aldehyde assisted fractionation (AAF), which relies on the protection of the native β-O-4 linkage of lignin with an aldehyde, can overcome this c

Carboxymethyl cellulose

Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a registered trademark of SE Tylose. Carboxymethyl cellulose is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid.

Excipient

An excipient is a substance formulated alongside the active ingredient of a medication, included for the purpose of long-term stabilization, bulking up solid formulations that contain potent active ingredients in small amounts (thus often referred to as "bulking agents", "fillers", or "diluents"), or to confer a therapeutic enhancement on the active ingredient in the final dosage form, such as facilitating drug absorption, reducing viscosity, or enhancing solubility.
