# Beta-peptide

Beta-peptides (β-peptides) are peptides derived from β-amino acids, in which the amino group is attached to the β-carbon (i.e. the carbon two atoms away from the carboxylate group). The parent β-amino acid is β-alanine (H$_2$NCH$_2$CH$_2$CO$_2$H), a common natural substance, but most examples feature substituents in place of one or more C-H bonds. β-peptides usually do not occur in nature. β-Peptide-based antibiotics are being explored as ways of evading antibiotic resistance. Early studies in this field were published in 1996 by the group of Dieter Seebach and that of Samuel Gellman.

## Structure

As there are two carbons available for substitution, β-amino acids have four sites (chirality included; as opposed to two in α-amino acids) for attaching the organic residue group. Accordingly, two main types β-amino acids exist differing by which carbon the residue is attached to: ones with the organic residue (R) next to the amine are called β$^3$ and those with position next to the carbonyl group are called β$^2$. A β-peptide can consist of only one kind of these amino acids (β$^2$-peptides and β$^3$-peptides), or have a combination of the two. Furthermore, a β-amino acid can form a ring using both of its sites and also be incorporated into a peptide.

## Synthesis

β-Amino acids have been prepared by many routes, including some based on the Arndt-Eistert synthesis.

## Secondary structure

Because their backbones are longer than those of normal peptides, β-peptides form disparate secondary structures. The alkyl substituents at both the α and β positions in a β-amino acid favor a gauche conformation about the bond between the α-carbon and β-carbon. This also affects the thermodynamic stability of the structure.
Many types of helix structures consisting of β-peptides have been reported. These conformation types are distinguished by the number of atoms in the hydrogen-bonded ring that is formed in solution; 8-helix, 10-helix, 12-helix, 14-helix, and 10/12-helix have been reported. Generally speaking, β-peptides form a more stable helix than α-peptides.

## Clinical potential

β-Peptides are stable against proteolytic degradation in vitro and in vivo, a potential advantage over natural peptides. β-Peptides have been used to mimic natural peptide-based antibiotics such as magainins, which are highly potent but difficult to use as drugs because they are degraded by proteolytic enzymes.

## Examples

β-Amino acids with a wide variety of substituents exist. Named by analogy to the biological α-amino acids, the following have been found naturally: β-alanine, β-leucine, β-lysine, β-arginine, β-glutamate, β-glutamine, β-phenylalanine and β-tyrosine.$^{:23}$ Of these, β-alanine is found in mammals and incorporated in pantothenic acid, an essential nutrient.$^{:2}$ Two α-amino acids are also structurally β-amino acids: aspartic acid and asparagine.$^{:218}$ Microcystins are a class of compounds containing a β-isoaspartyl (i.e. aspartic acid linked with its beta-carboxyl) residue.$^{:23}$

At Metacritic, which assigns a weighted average score out of 100 to reviews from mainstream critics, Echo Party received an average score of 71, based on 10 reviews, indicating "generally favorable reviews".
Rick Anderson of AllMusic said, "you'll hear vintage hip-hop basslines, 808 beats, and exuberant '80s-style rapping interspersed with weirdness like chopped-up Latin rhythms and shout-outs to New York boroughs and zodiac signs." Adam Kennedy of BBC called it "a production album over mere mixtape, one for the breakdancers, as well as appreciators of both forward-thinking and back-in-the-day craft." Nate Patrin of Pitchfork commented that "if you've ever wanted to hear classic cuts from the dawn of hip hop turned into hallucinogenic setpieces that knock and clang like glitched-up King Tubby, Echo Party should justify whatever the hell it is Edan's been doing with his time over the past four years."
Dave Segal of The Stranger included it on the "2009's Top Overlooked Releases" list.

# Ahitub (High Priest)

Ahitub (Hebrew: אֲחִיטוּב ʾĂḥīṭūḇ, "my brother is goodness" or "brother of goodness") was a High Priest of Israel cited in the Bible.
He was the son of Phinehas, grandson of Eli, and brother of Ichabod.
On the death of his grandfather Eli he most likely succeeded to the office of High Priest of Israel, and would have been succeeded by his son Ahijah (references to Ahitub as the father of Ahijah are in 1 Sam. 14:3; 22:9, 11, 12, 20 and 1 Chr 9:11). Ahijah (also spelled Ahiah), who is listed as his son in 1 Samuel 14:2-3, 18-19, may have been the same person as Ahimelech (1 Samuel 22:9-20), or he may have been another son of Ahitub (probably an elder son if this was the case).
# Matt Williams (equestrian)

Williams was brought up in Tonimbuk, Victoria and began riding at the age of three. He was introduced to the sport by his father, who had also been a show jumper. At the age of 18, Williams left Australia to ride in Europe.
At the 2008 Summer Olympics, he was the youngest Australian equestrian to have competed for Australia. In Beijing, he came in 21st individually and 7th with the Australian team.
He also appeared at the 2012 Summer Olympics. At the 2016 Summer Olympics competed with the horse Valinski S.
