How many amino acids would you find in a protein with a molecular weight of 50000?

The average molecular weight of proteins in yeast is about 50,000 with about 450 amino acids.

How do we calculate the molecular mass of an amino acid?

If the sequence of amino acids is known for any given protein, we can roughly estimate the molecular weight of the protein by multiplying the average molecular weight of amino acids with the total number of amino acids present in the protein. The average molecular weight of an amino acid is known to be 110 Daltons(Da).

What is the average molecular weight of an amino acid residue in a protein?

110Da
The average molecular weight of an amino acid is 110Da. Dalton (Da) is an alternate name for the atomic mass unit, and kilodalton (kDa) is 1,000 daltons. Thus a protein with a mass of 64kDa has a molecular weight of 64,000 grams per mole.

How many amino acids make up a protein?

twenty amino acids
Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.

How many amino acids are there?

20 amino acids
Of these 20 amino acids, nine amino acids are essential: Phenylalanine.

How many combinations of 20 amino acids are there?

There are 20 amino acids and any one of them can be at any position. Consider a chain that is 2 amino acids long. The first position can be any of 20 and the second can be any of 20, so there are a total of 20×20 or 400 possible combinations of two consecutive amino acids.

How many different Tripeptides can be made using the 20 commonly occuring amino acids?

20 x 20 x 20 = 8,000.

What is the average molecular weight of a protein?

A simple general calculation can be used to determine the base molecular mass of your protein. The average molecular mass for an amino acid is 110 Daltons (Da).

What is the average molecular weight of each amino acid?

around 128 Daltons
The average molecular weight of each amino acid is around 128 Daltons.

What is the average weight of an amino acid residue?

AAMC decided that we should know that an amino acid residue has an average weight of 110 Da which is equal to 110 g / mol for reference. IN is a 288-residue protein so it weights about 288 * 110 Da = 31680 Da.

How do you calculate the length of a tropomyosin strand?

Tropomyosin has two strands; each strand weighs 70 kD / 2 = 35 kD Each strand must have approximately (35 x 10^3 D)/ (110 D/residue) = 318 residues Assuming the entire strand is alpha helical, then the length is: 318 residues x 1.5 Angstroms/residue = 477 Angstroms

What is the molecular weight of an inactive tetramer of in?

There’s a question in the AAMC Section Bank that says that IN (integrase) is a 288-residue protein, and it’s asking what the molecular weight would be of an inactive tetramer of IN. The solution says that since the integrase monomer is composed of 288 amino acids, it will have a ~32 kDa, and thus the answer is 128 kDa for the size of a tetramer.

What is the shape of the protein described?

The shape of the protein described is: The translation (or rise) in a beta strand is 3.5 Angstroms/residue. 18 residues x 3.5 Angstroms/residue = 63 Angstroms
