Chalice
A chalice (from Latin 'mug', borrowed from Ancient Greek () 'cup') or goblet is a footed cup intended to hold a drink. In religious practice, a chalice is often used for drinking during a ceremony or may carry a certain symbolic meaning. Religious use Christian The ancient Roman ''calix'' was a drinking vessel consisting of a bowl fixed atop a stand, and was in common use at banquets. In Roman Catholicism, Eastern Orthodox Church, Oriental Orthodoxy, Anglicanism, Lutheranism and some other Christian denominations, a chalice is a standing cup used to hold sacramental wine during the Eucharist (also called the Lord's Supper or Holy Communion). Chalices are often made of precious metal, and they are sometimes richly enamelled and jewelled. The gold goblet was symbolic for family and tradition. Chalices have been used since the early church. Because of Jesus' command to his disciples to "Do this in remembrance of me." (), and Paul's account of the Eucharistic rite in ...

Kelch Motif
The Kelch motif is a region of protein sequence found widely in proteins from bacteria and eukaryotes. This sequence motif is composed of about 50 amino acid residues which form a structure of a four stranded beta-sheet "blade". This sequence motif is found in between five and eight tandem copies per protein which fold together to form a larger circular solenoid structure called a beta-propeller domain. Proteins containing Kelch motifs The Kelch motif is widely found in eukaryotic and bacterial species. Notably the human genome contains around 100 proteins containing the Kelch motif. Within individual proteins the motif occurs multiple times. For example, the motif appears 6 times in ''Drosophila'' egg-chamber regulatory protein. The motif is also found in mouse protein MIPP and in a number of poxviruses. In addition, kelch repeats have been recognised in alpha- and beta-scruin, in galactose oxidase from the fungus '' Dactylium dendroides'' and in the ''Escherichia co ...

Kelch Protein
Kelch proteins (and Kelch-like proteins) are a widespread group of proteins that contain multiple Kelch motifs. The kelch domain generally occurs as a set of five to seven kelch tandem repeats that form a β-propeller tertiary structure. Kelch-repeat β-propellers are generally involved in protein–protein interactions, though the large diversity of domain architectures and limited sequence identity between kelch motifs make characterisation of the kelch superfamily difficult. Structure The N-terminus of several Kelch proteins contain other protein domains, including Discoidin, F-box, and Broad-complex, Tramtrack, Bric-a-Brac/Poxvirus Zinc finger (BTB/POZ) domains. Kelch proteins may also only have a β-propeller architecture. The BTB domain of kelch proteins (if present) allows the formation of homo- or heterodimers that mediate protein–protein interactions. The C-terminus of Kelch proteins contains kelch repeats. Each kelch repeat is a sequence of 44–55 amino acids in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trappist Ale
Trappist beer is brewed by Trappist monks. Thirteen Trappist monasteries—six in Belgium, two in the Netherlands, and one each in Austria, Italy, England, France, and Spain—currently produce beer, but the ''Authentic Trappist Product'' label is assigned by the International Trappist Association (ITA) to just eleven breweries which meet their strict criteria. , Achel is no longer recognized as a Trappist brewery because it does not have any living monks. History The Catholic Trappist order originated in the Cistercian monastery of La Trappe, France. Various Cistercian congregations existed for many years, and by 1664 the Abbot of La Trappe felt that the Cistercians were becoming too liberal. He introduced strict new rules in the abbey and the Strict Observance was born. Since this time, many of the rules have been relaxed. However, a fundamental tenet that monasteries should be self-supporting is still maintained by these groups. Monastery brewhouses, from different religious ...
