Biomolecules, as physical systems, are distinct molecular entities synthesized or utilized by living organisms that exhibit specific structural, thermodynamic, and dynamical properties enabling biological function. They include nucleic acids, proteins, lipids, carbohydrates, and diverse metabolites, each characterized by defined covalent connectivity, three-dimensional conformations, and interaction potentials with solvents, ions, and other biomolecules. Their behavior is governed by quantum-mechanical bonding, classical electrostatics, and statistical thermodynamics, leading to emergent phenomena such as self-assembly, allostery, enzyme catalysis, and molecular recognition. In physical systems research, biomolecules are studied through techniques like spectroscopy, crystallography, cryo-EM, and molecular simulations to elucidate structure–function relationships and energy landscapes.
Modified lentil protein can act like fat in nonfat foods, especially yogurt, delivering creaminess and richness, according to a new study led by researchers at Penn State. The work, published in Food Chemistry, is the latest ...

Watermarks have long protected everything from bank notes and fine art to digital photographs and software, helping prove authenticity and trace an object's origin. Their main function is to protect copyright and verify authenticity.
Cell division is a complex process. At the heart of this complexity is a membraneless organelle called the centrosome, which is made up of more than 200 components. It is responsible for clustering mitotic spindles, threadlike ...
