Solvent extraction is the process of using a liquid or gaseous solvent to separate the solutes in a given sample. In extraction, separation is done through phase-separation, in which the two phases can be liquid-liquid, liquid-solid, and gas-solid. Liquid-liquid extraction is the most common...

A tripeptide is a specific type ofpeptide, or protein molecule, that is formed when three differentamino acidsjoin together. Each of these molecules contains three amino acids and threepeptide bonds. There are many different variations, and accordingly many different jobs and functions; in general,...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
Dry PAA is a white solid. It is capable of absorbing many times its weight in water, and hence is used in disposable diapers. Indiapers it is a fine powder - see picture of material form a diaper. Polyacrylic acid is found in a wide variety of household and personal care products: Dia...
