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.
Enzymes work consistently until they are dissolved, or become denatured. When enzymes denature, they are no longer active and cannot function. Extreme temperature and the wrong levels of pH -- a measure of a substance's acidity or alkalinity -- can cause enzymes to become denatured.nzyme Functions and Denaturation. An enzyme is a biological protein molecule made up of thousands of amino acids. Enzymes have specific functions in the body, such as working to break down food or causing other chemical processes.
