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.
Definition. noun. A type of chemical bond that is formed when the slightly positive hydrogen atom of a polar covalent bond forms an electrostatic link with the more electreonegative atom of a polar covalent bond in the same or another molecule. Supplement. A hydrogen bond is a weak type of chemical bond that is common in organisms. As the name suggests, this type of bond involves a hydrogen atom that is attracted to a strongly electronegative atom such as oxygen, fluorine, or nitrogen of a polar covalent bond in the same or another molecule.
