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

Which is better solvent: water or carbon tetrachloride?
Firdavs [7]
To know which is a better solvent between the two, one should know what will be the solute. It really depends on what type of solute you have. If the solute is polar then water is the better solvent for that type of solute. However, when the solute is a nonpolar substance then carbon tetrachloride is the better solvent.

what volume of silver metal Will Weigh exactly 2500 .0 g the density of silver is 10.5 g/ cm3 squared
vovangra [49]

Hello!

The formula is density =  mass / volume

                    => volume = mass / density

volume = ?

mass = 2500.0 g

density = 10.5 g/cm3

volume = mass / density

volume = 2500.0 g / 10.5 g/cm3

volume = 2380.95 cm3

Hope this help!
