What is the common name of the plant hedera helix?
Hedera helix Hedera helix Hedera helix, the common ivy, English ivy, European ivy, or just ivy, is a species of flowering plant in the family Araliaceae, native to most of Europe and western Asia. A rampant, clinging evergreen vine, it is a familiar sight in gardens, waste spaces, on house walls, tree trunks and in wild areas across its native habitat. "Hedera" is the generic term for ivy. The specific epithet "helix" derives from Ancient Greek "twist, turn" (see: Helix), and from the Latin "helicem", "spiral-shaped," first used around 1600. Synonyms include "Hedera acuta", "Hedera arborea" ("tree ivy"), "Hedera baccifera", "Hedera grandifolia",
Alpha helix Alpha helix The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand-spiral conformation (i.e. helix) in which every backbone N−H group donates a hydrogen bond to the backbone C=O group of the amino acid located three or four residues earlier along the protein sequence. The alpha helix is also called a classic Pauling–Corey–Branson α-helix. The name 3.6-helix is also used for this type of helix, denoting the average number of residues per helical turn, with 13 atoms being involved in the ring formed by the hydrogen bond.
