The discovery date of phosphorus is usually considered to be 1669, but there are some indications that it was known earlier. Gepher, for example, reports that in an alchemical manuscript from a collection stored in the Paris Library, it is said that around XII
Molecule structure. Sulfuric acid. Formula, properties, preparation and application Molecular formula h2so4
Acids are chemical compounds consisting of hydrogen atoms and acidic residues, for example, SO4, SO3, PO4, etc. They are inorganic and organic. The first include hydrochloric, phosphoric, sulfide, nitric, and sulfuric acid. To the second - uk
Thermodynamics of adsorption processes
In the case of interaction of two atoms: U – interaction energy; U = U ATTRACTION. + U OTTALK. - Lennard-Jones equation, c, b, m = const In cases of interaction of atoms with a solid surface, it is necessary to sum up all interactions. x – distance

Biosynthesis of purine nucleotides
Decomposition of purine nucleotides. Adenosine and guanosine, which are formed during the hydrolysis of purine nucleotides, undergo enzymatic breakdown to form the final product - uric acid, which is excreted in the urine from the body. Decomposition of pyrimidine nucleotides
Optical properties of nanoparticles
Optical absorption spectroscopy is one of the oldest methods for the physicochemical analysis of biomolecules. However, its low sensitivity and spatial resolution do not allow studying processes involving low protein concentrations. Scientists from Berkeley
Conformation, size and shape of macromolecules
The essence and variants of structural isomerism, as well as an initial idea of spatial isomerism, are presented in Lecture 2. Let us consider in more detail the following characteristic of the structure of individual macromolecules - the configuration of macromolecules. Lecture 4. Continued
