Denaturation is the process by which foods or liquids are made unpleasant or dangerous to consume; it is done by adding a substance known as a denaturant. Aversive agents —primarily bitterants and pungent agents —are often used to produce an unpleasant flavor.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Polyphenol oxidase is an enzyme found throughout the plant and animal kingdoms, [31] including most fruits and vegetables. [32] PPO has importance to the food industry because it catalyzes enzymatic browning when tissue is damaged from bruising, compression or indentations, making the produce less marketable and causing economic loss.
For example, most plants are photolithoautotrophic, since they use light as an energy source, water as electron donor, and CO 2 as a carbon source. All animals and fungi are chemoorganoheterotrophic , since they use organic substances both as chemical energy sources and as electron/hydrogen donors and carbon sources.
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2]
Denaturation (biochemistry), a structural change in macromolecules caused by extreme conditions; Denaturation (fissile materials), transforming fissile materials so that they cannot be used in nuclear weapons; Denaturation (food), intentional adulteration of food or drink rendering it unfit for consumption while remaining suitable for other uses
Family 1 includes Stearoyl-CoA desaturase-1 (SCD) (EC 1.14.19.1). [17] Family 2 is composed of: Bacterial fatty acid desaturases. Plant stearoyl-acyl-carrier-protein desaturase (EC 1.14.19.1), [18] an enzyme that catalyzes the introduction of a double bond at the delta-9 position of steraoyl-ACP to produce oleoyl-ACP. This enzyme is responsible ...
Examples of sources of gluten (clockwise from top): wheat as flour, spelt, barley, and rye as rolled flakes Gluten is a structural protein naturally found in certain cereal grains . [ 1 ] The term gluten usually refers to the elastic network of a wheat grain's proteins, gliadin and glutenin primarily, that forms readily with the addition of ...
