In a combustion reaction, fuel is burned and reacts with oxygen to release energy. Respiration is the chemical change that takes place inside living cells. Glucose and oxygen are used to release ...

Delayed anaphylaxis can start an hour or more after peanut exposure, sometimes days later. Symptoms include swelling, wheezing, weak pulse, hives, vomiting, and confusion. Biphasic anaphylaxis can ...

Carboxylic acids can undergo reduction reactions. Reduction is the opposite of oxidation. For example, ethanoic acid (CH 3 COOH) can be formed by the oxidation of ethanol as shown below. As reduction ...

A biochemical reaction is the transformation of one molecule to a different molecule inside a cell. Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the ...

Predicting chemical reactions remains a challenge. Here, the authors present Loxodynamics, a machine learning method that uses statistical skewness to automatically discover reaction pathways in ...

Biphasic anaphylaxis is a second anaphylactic reaction after successful treatment, without new allergen exposure. It can occur up to 72 hours later, often peaking within 8 to 11 hours. Symptoms can ...

People often have an unpleasant reaction to something they have eaten and think they have a food allergy. But they may be having something else: a reaction called food intolerance. What's the ...

Utrecht University researchers Rodolfo Subert and Marjolein Dijkstra show in their latest study that complex three-dimensional networks in materials can emerge from nothing more than particle shape.
