Hydrogen burns with a loud pop in when a burning splint is held near it.

<h3>Test for hydrogen</h3>

There are a couple of ways to test for hydrogen. However, the simplest and most popular way is to bring a burning splint near a container containing hydrogen gas.

The production of a loud squeaky pop sound indicates the presence of hydrogen gas. All precautions should, however, be observed.

hydrolysis of decapeptide P with the enzyme trypsin affords the following fragments: Glu-Gly-Lys, Gln-Val-Ile, Ala-Ser-Phe-Lys.
ehidna [41]

Answer:

The sequence of an amino acid P is:

Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile

Explanation:

Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named trypsin:

  • Glu-Gly-Lys,
  • Gln-Val-Ile
  • Ala-Ser-Phe-Lys

Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named chymotrypsin:

  • Lys-Gln-Val-Ile,
  • Glu-Gly-Lys-Ala-Ser-Phe

In order to determine the sequence of protein P , we will arrange fragments in such a way so that common fragments or the common parts of fragments should come under each other.

On arranging these fragments :

Glu-Gly-Lys-Ala-Ser-Phe

Glu-Gly-Lys

                   Ala-Ser-Phe-Lys

                                         Lys-Gln-Val-Ile

                                                Gln-Val-Ile

The sequence of an amino acid P is:

Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
