A material is brittle if, when subjected to stress, it breaks without significant deformation (strain). Brittle materials absorb relatively little energy prior to fracture, even those of high strength.Breaking is often accompanied by a snapping sound.any steels become brittle at low temperatures (see ductile-brittle transition temperature), depending on their composition and processing. When used in materials science, it is generally applied to materials that fail when there is little or no evidence of plastic deformation before failure.
Denaturation. Definition. noun. (1) A process in which the folding structure of a protein is altered due to exposure to certain chemical or physical factors (e.g. heat, acid, solvents, etc.), causing the protein to become biologically inactive.
1 a denatured protein has a different tertiary structure than its native state. 2  egg white meringue contains denatured proteins. 3  soakin fish in lime juice to make ceviche denatures the proteins.  digestive enzymes hydrolyze proteins.
