What else can I help you with?
Can a chain structure model be a alpha or beta?
alpha
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 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 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?
In proline the H2NC-COOH is not free rotatable (around C-C linkage) because it is 'build in' in a ring. (Sorry that this lousy text editor doesn't allow me to draw this structure to make it clear to you how)
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
Why proline amino acid gives yellow colour in reaction with ninhydrin?
Yes. Within "The Chemical Reactions of Amino Acids / Reactions of Amino Groups" there are several examples - one of which is the ninhydrin reaction. A very widely applied reaction of the alpha amino group [that is the N in the peptide bond -CCN-CCN-], it is used to estimate the quantity of amino acids [in a sample] in very small amounts. All amino acids and polypeptides with a free alpha group react with ninhydrin and yield [or produce] an intensely purple colored product - except for Proline and Hydroxyproline {both in which the alpha amino group is termed to be 'substituted' - something to do with carbon rings} which "yield derivatives with a characteristic yellow color." See also 'Schiff's bases'.
An alpha particle has the same structure as which nucleus?
The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.
What is the structure of fructofuranose?
alpha- D- fructofuranose
What type of structure does hemoglobin have?
Alpha helices

What is the crystal structure of polonium?
The structure of polonium alpha form is cubic.The structure of polonium beta form is rhombohedral.
