Alpha helices are a type of secondary structure in proteins. What is the length of a 27.0 kDa single‑stranded α‑helical protein

iogann1982 [59]

Answer : The length of protein will be, 36.8 A⁰

Explanation :

First we have to calculate the amino acid residue.

$\text{Amino acid residue}=\frac{\text{Length of single strand of protein}}{\text{Mean residue mass}}$

Given:

Length of single strand of protein = 27.0 kDa

Mean residue mass = 110 Da

$\text{Amino acid residue}=\frac{27.0kDa}{110Da}=\frac{27000Da}{110Da}=245.4$

Now we have to calculate the number of turns in protein.

$\text{Number of turns in protein}=\frac{\text{Amino acid residue}}{3.6\text{amino acid per turn of the alpha-helix}}$

As there are 3.6 amino acid per turn of the alpha-helix.

$\text{Number of turns in protein}=\frac{245.4}{3.6}=68.17$

Now we have to calculate the length of the protein.

$\text{Length of protein}=\text{Number of turns in protein}\times \text{Length of each turn}$

As, we know that the length of each turn = 0.54 A⁰

$\text{Length of protein}=68.17turns\times 0.54\AA=36.8\AA$

Thus, the length of protein will be, 36.8 A⁰

En la practica de la papa,¿a que atribuyes el hecho de la rapidez de reacción?

GaryK [48]

Answer:

El rendimiento de tubérculos de la papa es vulnerable a las altas temperaturas y se ve desafiado por el aumento asimétrico de las temperaturas diurnas y nocturnas. Este estudio tuvo como objetivo evaluar la fotosíntesis, el crecimiento de biomasa, la distribución de la masa de tubérculos y el rendimiento de tubérculo seco en papas cosechadas temprano que se cultivaron en el campo bajo condiciones de alta temperatura diurna y nocturna durante diferentes etapas de crecimiento.
