If 600 amino acids are condensed to form a protein, how many peptide bonds are being formed? How many molecules of H2O are split out during the condensation? If the average molecular weight of a free amino acid is 130 daltons, what is the molecular weight of the protein?

Answer #1

Answer. Peptide bond formed between amino group of one amino acid and carboxylic group of another.

Total amino acid - 600

1 peptide bond occurs between 2 amino acid and 2 peptide bonds occur between 3 amino acid ................then 599 peptide bonds occur between 600 amino acid

1 H20 molecule release when formation of a peptide bond

Total water molecule released during formation of this polypeptide - 599

Molecular weight of one water molecule -18

Molecular weight of one free amino acid - 130 dalton

Molecular weight of protein - 600×130 - 18× 599 = 78000 - 10782 = 67218 Dalton

How do differences in amino acid sequences lead to different protein functions? A. Different amino acids produce different proteins based on the bonds formed between them B. Differences in amino acids lead to the recycling of proteins, which produces other functional proteins. C. Different amino acids cause rearrangements of amino acids to produce a functional protein. D. Differences in the amino acids cause post-translational modification of the protein, which reassembles to produce a functional protein.

What is the energy produced from digesting Turkey (protein). Turkey (protein) many essential amino acids such as tryptophan, threonine, isoleucine, lysine and phenylalanine. Threonine is a large amino acid and will broken be down into two products: pyruvate and succinyl CoA which are then fed into the citric acid cycle and electron transport chain. Phenylalalanine is broken down into acetyl CoA and fumarate and fed into the citric acid cycle and electron transport chain. Please write down all the calculations...

An oligomeric protein has a molecular weight of 219000. A 650 mg sample was treated with an excess of 1-fluoro-2,4-dinitrobenzene (Sanger\'s reagent) until the reaction was complete. Next the peptide bonds were hydrolyzed by heating with concentrated HCl. The product of the complete hydrolysis contained 4.9 mg of the compound shown below, and no other 2,4-dinitrophenyl derivatives of the α-amino groups of other amino acids could be found. How many polypeptide chains are in this protein? (Enter your answer as...

During a voyage to England in 1757, Benjamin Franklin observed, as had sailors for centuries before him, that when cooking grease was thrown from the ship’s galley onto the water, the waves were calmed by the film that formed on the ocean surface. In 1765, Franklin followed up on this observation by placing one teaspoonful (~5 mL) of a fatty acid “oil” on a half-acre pond (roughly 2 × 107 cm2 ), which was just sufficient to form a condensed...
