The alpha helix is a smaller structure than a beta helix since the beta helix involves bonding between two and often more than two strands. A beta helix structure has been found in some enzymes and in antifreeze proteins of certain insects. The beta helix is larger and it involves more residues per turn when compared with the alpha helix.

Wikipedia describes beta barrels as used for porins, preprotein translocases, and lipocalins. To me, a coiled coil alpha helix structure could surely perform the same functions and given the vast number of proteins using alpha helices there might be some out there.. So my question is twofold: The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid located four residues earlier along the protein sequence. The alpha helix is also called a classic Pauling–Corey–Branson α-helix. The alpha helix is a rod-like structure whose inner section is formed by a tightly coiled main chain, with its side chains extending outward in a helical array.

The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand - helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid located four residues earlier along the protein sequence. The alpha helix is a rod-like structure whose inner section is formed by a tightly coiled main chain, with its side chains extending outward in a helical array. The alpha helix structure takes advantage of the hydrogen bond between CO and NH groups of the main chain to stabilize. Pauling first described the alpha-helix nearly 50 years ago, yet new features of its structure continue to be discovered, using peptide model systems, site-directed mutagenesis, advances in theory, the expansion of the Protein Data Bank and new experimental techniques.

An α-helix is a right-handed coil of amino-acid residues on a polypeptide chain, typically ranging between 4 and 40 residues.

This coil is held together by hydrogen bonds between the oxygen of C=O on top coil and the hydrogen of N-H on the bottom coil. This video talks about the alpha helix structure of proteins.The α helix, a common structural motif of proteins, consists of a right-handed helix with a repe An alpha helix is an element of secondary structure in which the amino acid chain is arranged in a spiral. The kinemage linked above shows an individual alpha helix, viewed from the N-terminal end to resemble the "helical wheel" (see figure below).

When a number of successive peptide links have identical rotations the polypeptide chain takes up a particular secondary structure. This video talks about the alpha helix structure of proteins.The α helix, a common structural motif of proteins, consists of a right-handed helix with a repe The picture to the left shows the alpha helix which is the polypeptide chain that makes up human hair. In one single strand of hair, three alpha helices are twisted together to form a protofibril . Then, nine protofibril join together in a circle around two or more to form … 2021-04-09 2020-09-02 Hair Structures & the Alpha Helix Design - uGo Deep Short Course Guidance This "uGo Deep Short Course" supports purchasers of the Hair Structure Science - Poster Sheet 1 to go deeply into the biological structures in hair from the root to the elemental level.

Helical peptides in solution form a vast number of structures, including fully The α-helix is the most common peptide secondary structure, constituting almost half of the polypeptide structure in proteins. First proposed by Hamilton, a notable entry to α -helix mimetics consisted of molecular templates based on the terphenyl ( 7 ) [72] and terpyridyl ( 8 ) scaffolds [73] ( Fig. 6.16 ).
