Short hydrogen bonds in proteins and their quantum mechanical nature

The assembly of linear polypeptide chains into functional three-dimensional protein architectures involves a unique force called hydrogen bonding. A typical hydrogen bond forms when the donor and acceptor groups approach each other with a nearly linear geometry

Atom tunneling in chemistry

While macroscopic objects from everyday life follow the classical laws of physics, microscopic objects obey the laws of quantum mechanics. These quantum objects, such as light (photons), electrons, and atoms, show characteristics of particles as well as

Wait a minute, how come heavier reacts faster?! Quantum effects in biochemistry and medicine

Physics is often thought to be quite irrelevant to Biochemistry and Medicine.  But, the very first Physics Nobel Prize in 1901, for the discovery of X-rays, is highly related to Medicine nowadays.  This clearly shows that a
