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.
Hydroflouric and formic acids have a special type of hydrogen bond called a symmetric hydrogen bond. This bond is much stronger than a regular hydrogen bond, and can be seen in these acids when they are kept at a high pressure. Hydrogen bonds between proteins result in a phenomenon known as protein folding.
