Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.
In the field of structural biology, certain molecules are so uncommon that they can only be captured with a special set of tools.
In Huntington's disease, a faulty protein aggregates in brain cells and eventually kills them. Such protein aggregates could, in principle, be prevented with a heat shock protein.
Investigators from the Institute of Scientific and Industrial Research at Osaka University, together with the Hiroshima Institute of Technology, have announced the discovery of a new protein that allows an organism to conduct an initial and essential step in converting amino acid residues on a crosslinked polypeptide into an enzyme cofactor.
The lens of the human eye gets its transparency and refractive power from the fact that certain proteins are densely packed in its cells.
Findings from a new study on Alzheimer's disease could eventually help clinicians identify people at the highest risk for developing the progressive brain disorder.
In cells, numerous important biochemical functions take place within spherical chambers made from proteins and RNA.
Correct, or native, protein folding is essential for correct protein function. Protein misfolding can lead to the formation of amyloid fibrils, and amyloidosis, which is implicated in various human neurodegenerative diseases, including Parkinson's, Alzheimer's, and Huntington's diseases.
The study concludes that vegan diet has a broad effect on children's metabolism. Serum biomarker levels for vitamins A and D, cholesterol forms and essential amino acids were significantly lower in children on vegan diet compared to age-adjusted omnivores.
The SARS-CoV-2 virus may enter and replicate in human cells by exploiting newly-identified sequences within cell receptors, according to work from two teams of scientists.
Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling.
A team of HIV researchers, cellular biologists, and biophysicists who banded together to support COVID-19 science determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells.
Nitrogen is one of the most essential nutrients for plants. Its availability in the soil plays a major role in plant growth and development, thereby affecting agricultural productivity.
Cancers like melanoma are hard to treat, not least because they have a varied bag of tricks for defeating or evading treatments.
An ischemic stroke occurs when the homeostasis of the body and brain is highly disrupted. The immune system, among other things, activates an inflammatory response that can either overshoot or change into an immune deficiency.
L-DOPA is a drug used for treating Parkinson’s disease, and now researchers have created a tomato that is enriched with this drug. This innovation could lead to a new, inexpensive source of one of the most essential medicines in the world.
Comprehensive identification of viral proteins encoded by viral genes is required to understand the pathophysiology of viral infections.
Michael Gross, professor of chemistry in Arts & Sciences at Washington University in St. Louis and of immunology and internal medicine at the School of Medicine, and his team are experts in footprinting proteins -- that is, using advanced methods for investigating the structure and interactions of proteins within larger molecules.
Biologists have analyzed the genes that establish the composition of fatty acids in flaxseed oil and detected polymorphisms in six of those genes.
As medical research progresses, traditional treatment protocols are being rapidly exhausted. New approaches to treat diseases that do not respond to conventional drugs are the need of the hour.
A new study has revealed how a disease-causing parasite is able to resist the present range of therapies. The study was recently published in eLife.
