Metabolism is the means by which the body derives energy and synthesizes the other molecules it needs from the fats, carbohydrates and proteins we eat as food, by enzymatic reactions helped by minerals and vitamins.
The majority of organisms feature the series of ENDOU enzymes, but despite this fact, the functions of these enzymes have not been properly understood.
One of the most significant greenhouse gases that cause global warming is nitrous oxide (N2O).
Biologically active compounds from the marine fungus Penicillium dimorphosporum protect cells from paraquat, the highly toxic herbicide with no remedy, and might enhance the action of some drugs.
Several plant pathogens belong to the genus Verticillium and affect many different plant hosts.
Disorders of the cells' energy supply can cause a number of serious diseases, but also seem to be connected to aging.
The gut microbiome is considered an essential part of the body, but its significance in the human aging process is still vague.
An international research team has uncovered the shape of the glutamate transporter and helps explain how the human brain cells interact with each other.
Several biological processes are subject to rhythmic variations. Popular examples of this include the supposed circadian rhythm.
Green tea contains an antioxidant that may boost the concentrations of p53, called the “guardian of the genome,” for its potential to kill cancerous cells.
A better understanding of cellular interactions is crucial to interpret several biological diseases and systems.
Researchers at Linköping University, Sweden, have developed biosensors that make it possible to monitor sugar levels in real time deep in the plant tissues - something that has previously been impossible.
A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.
When two naturally occurring lipids are altered using a process called epoxidation, they are transformed into powerful agents that target numerous cannabinoid receptors in neurons, disrupting pathways that promote inflammation and pain.
A new technique has revealed the natural structure of specifically massive and complex enzymes.
In a study conducted at the University of Helsinki, Finland, 136 adults adhered to one of three study diets for 12 weeks. One of them corresponded to the average Finnish diet, containing roughly 70% animal-derived protein of total protein, while most of the plant-based protein originated from cereal products.
Prompted by the need to improve conventional treatments for people infected with the human immunodeficiency virus (HIV-1), a team from the Institut national de la recherche scientifique (INRS) has identified a therapeutic approach to restore the effectiveness of immune cells.
Neanderthals' gut microbiota already included some beneficial micro-organisms that are also found in our own intestine.
A City of Hope-led research team found that the same gene that increases the risk for Alzheimer's disease, ApoE4, can increase the susceptibility to and severity of COVID-19.
Mehmet Orman, assistant professor of chemical and biomolecular engineering at the University of Houston Cullen College of Engineering, has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation.
In a new study led by Yale Cancer Center, researchers have discovered a novel metabolic gatekeeper mechanism for leukemia. This mechanism depends on a molecule called PON2, which could lead to a new treatment for the disease. The findings were published online today in the Proceedings of the National Academy of Sciences (PNAS).
