ART significantly extends the likelihood of surviving for several decades, according to the U.S. Department of Health & Human Services. If untreated, HIV-positive persons typically live in clinical latency for around 10 years. Individuals on ART are not likely to have their HIV infection reach the AIDS stage. If the viral infection progresses to that stage, survival is estimated at around three years.
Key concepts: A hydrogen bond is formed by the interaction of a hydrogen atom that is covalently bonded to an electronegative atom (donor) with another electronegative atom (acceptor). Hydrogen bonding confers rigidity to the protein structure and specificity to intermolecular interactions.
Hydrogen atoms only need two electrons in their outer level to reach the noble gas structure of helium. Once again, the covalent bond holds the two atoms together because the pair of electrons is attracted to both nuclei. Hydrogen chloride. The hydrogen has a helium structure, and the chlorine an argon structure.
