1B). Almost  Structure similarities between both eukaryotic ferritins and prokaryotic ferritins have been extensively demonstrated. However, there is an essential difference  This precludes hydrogen bonding between it and hydrogen bond acceptors, and thus often restricts the residue to the first four positions of an a-helix. Helices with   The sequence CAD is a little larger than half of a loop of the peptide backbone helix.

An alpha helix is a commonly-found protein secondary structure. It is a right-handed coil in which every backbone N-H group donates a hydrogen bond to the C=O group of the amino acid four residues earlier. This secondary structure is also sometimes called a classic Pauling–Corey–Branson alpha helix. The Alpha Helix, Beta Sheet, and Beta Turn.

10 Jan 2011 The alpha helix is the most common helix found in nature. It consists of a coiled polypeptide chain, in which the side chains of the amino acids 

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 an 11 stranded cable that is called microfibril. 3d structure of a protein is made up several secondary structure elements like helices and sheets.

The alpha helix structure takes advantage of the hydrogen bond between CO and NH groups of the main chain to stabilize.

Alpha helix structure

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.

Alpha helix A common motif in the secondary structure of proteins, the alpha helix (α-helix) is a right- or left-handed coiled conformation, resembling a spring, in which every backbone N-H group donates a hydrogen bond to the backbone Full article alpha helix A spiral shape constituting one form of the secondary structure of proteins, arising from a specific hydrogen-bonding structure.

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.
