Description
Lecithin from eggs is a biochemical-grade phospholipid preparation intended for laboratory use in membrane, emulsion and lipid-chemistry work. Identified by CAS number 93685-90-6 and EG number 232-307-2, the material shows a density below 1 g/cm³. Egg-derived lecithin provides a natural mixture of phosphatidylcholines and related lipids widely applied in liposome formulation, surfactant studies, model membrane systems and biochemistry teaching. This grade from manufacturer Carl ROTH is positioned for biochemical applications where a reliable egg lecithin source is needed for dispersion, coating or reconstitution protocols. The plastic packaging supports convenient bench handling of the solid or semi-solid material during weighing and stock preparation. Research groups working on colloidal systems, lipid bilayers or nutritional biochemistry can incorporate this lecithin into standard laboratory procedures. Clear CAS and EG identifiers aid inventory control and method documentation across analytical and life-science environments.

Questions about Lecithin, from eggs, for biochemistry, 25 g, plastic
What is this article?
Lecithin, from eggs, for biochemistry, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Lipids, steroids & fatty acids, inside Biochemicals & reagents, in Microbiology lab supplies.
A lipid, a steroid or a fatty acid is specified by chain length, saturation and purity. Esters and free acids are different compounds. Many are supplied in a small amount under inert gas because they oxidise. The physical form, oil or powder, follows from the structure.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
