No , there is no specific sequence for the alpha amino acids formation . alpha helix mostly contain methionine , alanine , lysine , leucine and glutamate due to their high helix forming properties as compared to other amino acids. alpha helix has no specific sequence of amino acids but show 3.6 residue per turn.
is there a specific sequence of amino acids required for an alpha helix to form. explain...
A protein with the sequence below forms an alpha-helix. How many turns are made in the helix? Explain why the properties of the amino acids in this helix result in an amphipathic protein. How might this amphipathic alpha-helix associate with the membrane? Leu-Lys-Arg-Ile-Val-Asp-Thr-Ile-Leu-Ser-Arg-Leu-Phe-Lys
1.) Why is it that amino acids in proteins are called a-amino acids? 2.) explain alpha, amino, and acid . Please answer questions 1&2 !
Which amino acid is cannot be found in an alpha helix? Explain.
Why will the phi/psi angles of an amino acid in an alpha-helix be different from the phi/psi angles of an amino acid in a beta-sheet? How are phi/psi angles possible fro Pro and for Gly different from those of other amino acids?
22. Consider an alpha helix with sequence VLADWMAVELA, and consider the hydrogen bonds that are required in order to form the alpha helix. A. Fill in all of the hydrogen bonds that must form between a given residue's backbone N-H backbone C-O, or R group, indicating what the hydrogen bonding partner for each will be. For example, the C-O of V1 is a hydrogen bond acceptor of the W5 N-H hydrogen bond donor, reflected in the appropriate squares under V1...

Understand alpha helices and beta pleated sheets Question How is it possible for the a-helix to have amino acids with bulky side chains while the B-pleated sheets cannot? Select the correct answer below: O The R groups in the a-helix stabilize the structure, while they interfere with the hydrogen bonds in a B-pleated sheet. The R groups are contained inside the a-helix structure, while they interfere with the hydrogen bonds in a B- pleated sheet. O The R groups lie...
4. In contrast to the alpha amino acids which are ubiquitous in nature, beta amino acids (with an extra carbon in the backbone) are quite rare. They form secondary structures that have very different conformations from traditional proteins. For instance, the compound shown below is the simplest beta amino acid; unusually, it is most stable in a gauche conformation. Draw it and explain why, co, Corn lonic c Hdi athrachan H₂N HT 5. Quebrachitol is a naturally occurring compound found...
alpha-Ketoglutarate plays a central role in the biosynthesis of several amino acids. Write a sequence of enzymatic reactions that could results in the NET synthesis of alpha-ketoglutarate from pyruvate. You may use other cofactors as required (e.g. NADH, ATP). There is no need to show structures, but indicate the name of each intermediate, the name of the enzyme, and balance each reaction for cosubstrates and cofactors. Each of the carbons in your alpha-ketoglutarate product must have originated from pyruvate.
Please draw the helical wheel diagram for the sequence CANDLES. Is this alpha helix hydrophilic, hydrophobic for amphiphatic. What unique supersecondary structure with this Heptad form and why?
