Life may not have begun with a dramatic lightning strike into the ocean but from many smaller "microlightning" exchanges ...

Electricity causes the rearrangement of electrons and atoms from water molecules. Two hydrogen atoms covalently bond to form hydrogen gas. Two oxygen atoms covalently bond to form oxygen gas. There ...

Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds. Hydrophobic side chains interact with each other via weak van der Waals interactions.

A team of researchers of the Department of Physics studied the use of two-dimensional materials, formed by a single atomic ...

Nature ion channels play significant role in the living organisms, which can translocate physiological relevant ions across the cell membranes as demand. To simulate and replace the function of nature ...

How can we produce clean hydrogen without burning fossil hydrocarbons or other non-renewable energy sources? We can do so ...

Hydrogen is typically impossible to study in liquid form—it becomes a solid at -259°C (-434°F). But by confining small clusters of hydrogen molecules inside helium nanodroplets at -272.25°C ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

Amino acids can be joined together through peptide bonds to form peptides and proteins ... which are stabilized by various interactions, including hydrogen bonds, disulfide bridges, and hydrophobic ...
