Can a chain structure model be a alpha or beta?
alpha
What element has atomic structure similar to an alpha particle?
The element with atomic structure similar to an alpha particle is helium. An alpha particle consists of two protons and two neutrons, the same as the nucleus of a helium atom.
What fiber is strong and composed of dense fibrous proteins?
connective tissue in animals is composed of many different proteins including collagen. Collagen is a protein that is composed of 3 left handed alpha helices interwoven with one another, which gives it great strength. Collagen is a rare example of a left handed alpha helix, and is thought to occur as such due to the post translational hydroxylation of the proline residues (proline typically does not occur in alpha helices because it distorts the helix).
What type of interaction stabilizes the secondary structure of a protein causing it to form an alpha-helix?
Hydrogen bonds between the carbonyl oxygen of one amino acid and the amine hydrogen of an amino acid that is four residues down the sequence stabilize the formation of an alpha-helix in a protein. This creates a helical backbone structure that provides stability to the protein's secondary structure.
Do the alpha particles in Rutherford's experiment contain electrons?
No, alpha particles are helium nuclei made up of two protons and two neutrons, with no electrons. In Rutherford's experiment, alpha particles were used to probe the structure of atoms by scattering off the positive nucleus, helping to reveal the atom's structure.
Which amino acid has no free alpha amino group?
Proline is the amino acid that does not have a free alpha amino group in its side chain. This is because proline's side chain cyclizes back to the amino group, forming a unique structure that lacks a free alpha amino group.
Which amino acid has its alpha nitrogen in a ring?
Proline has an alpha nitrogen in a ring.
1 Proline is the amino acid least commonly found in alpha-helices but most commonly found in beta-turn discuss the reason for this behavior?
Proline has a rigid cyclic structure that limits its conformational flexibility, making it less favorable for the regular structure of alpha-helices. In contrast, the unique structure of proline allows it to be commonly found in turns, such as beta-turns, where its rigidity helps to stabilize the turn structure and facilitate changes in direction. This behavior is due to the specific structural and conformational constraints imposed by proline, influencing its prevalence in different protein secondary structures.
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
Can a chain structure model be a alpha or beta?
alpha
An alpha particle has the same structure as which nucleus?
An alpha particle has the same structure as a helium nucleus, consisting of two protons and two neutrons.
Why proline amino acid gives yellow colour in reaction with ninhydrin?
Proline contains a secondary amine group in its side chain that reacts with ninhydrin, forming a yellow-colored product. This reaction results in the formation of a cyclic product known as a pyrrolidine derivative that is yellow in color.
What is the structure of fructofuranose?
alpha- D- fructofuranose
What type of structure does hemoglobin have?
Alpha helices
What element has atomic structure similar to an alpha particle?
The element with atomic structure similar to an alpha particle is helium. An alpha particle consists of two protons and two neutrons, the same as the nucleus of a helium atom.
What is the crystal structure of polonium?
The structure of polonium alpha form is cubic.The structure of polonium beta form is rhombohedral.
What fiber is strong and composed of dense fibrous proteins?
