Alpha helices are a type of secondary structure in proteins. What is the length of a 33.0 kDa single‑stranded α‑helical protein

WARRIOR [948]

Answer:

450 Å

Explanation:

The amino acids in an α-helix are arranged in a right-handed helical structure where each amino acid residue corresponds to a 100° turn in the helix, and a translation of 1.5 Å (0.15 nm) along the helical axis

Mass of protein= 33.0 kDa

33.0 kDa ×(1000Da/kDa) × ( 1 residue/ 110 Da)

=33.0 ×1000 × 0.0091

= 300 residues

300 residues × (1.5Å /residue)

=450 Å

Answer:

The number of neutrons present in one atom of isotope of Silicon of mass 28 amu is 14 neutrons

Explanation:

Symbol of Si isotope

$_{14}^{28}\textrm{Si}$

Number of Neutron = Mass number - Atomic Number

Mass number = Total number of protons and neutrons present in the nucleus of the atom.For Si = 28 amu

Atomic Number = Total number of Protons present in the nucleus.

Si = 14

Number of neutron = 24 - 14

= 14
