Clathrate compound. A clathrate is a chemical substance consisting of a lattice that traps or contains molecules. The word clathrate is derived from the Latin clathratus (clatratus), meaning 'with bars, latticed '. [1] Most clathrate compounds are polymeric and completely envelop the guest molecule, but in modern usage clathrates also include ...
Food chemistryis the study of chemicalprocesses and interactions of all biological and non-biological components of foods. [1][2]The biological substances include such items as meat, poultry, lettuce, beer, milkas examples. It is similar to biochemistryin its main components such as carbohydrates, lipids, and protein, but it also includes areas ...
Reducing form of glucose(the aldehyde groupis on the far right) A reducing sugaris any sugarthat is capable of acting as a reducing agent.[1] In an alkalinesolution, a reducing sugar forms some aldehydeor ketone, which allows it to act as a reducing agent, for example in Benedict's reagent. In such a reaction, the sugar becomes a carboxylic ...
Compounds with P-C and P-O-C bonds are often classified as organophosphorus compounds. They are widely used commercially. The PCl 3 serves as a source of P 3+ in routes to organophosphorus(III) compounds. For example, it is the precursor to triphenylphosphine: PCl 3 + 6 Na + 3 C 6 H 5 Cl → P(C 6 H 5) 3 + 6 NaCl
A mixture is a material made up of two or more different chemical substances which can be separated by physical method.It is an impure substance made up of 2 or more elements or compounds mechanically mixed together in any proportion. [ 1 ] A mixture is the physical combination of two or more substances in which the identities are retained and ...
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical ...
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
This compound also exists in equilibrium with various oligomers (short polymers), depending on the concentration and temperature. A saturated water solution, of about 40% formaldehyde by volume or 37% by mass, is called "100% formalin". A small amount of stabilizer, such as methanol, is usually added to suppress oxidation and polymerization. A ...
