<span>The addition and subtraction of negatively charged electrons can easily change an atom’s charge, because they perpetually spin in valence shells outside the nucleus. It is easier for a neighboring atom to share or steal an electron rather than a positively charged proton, which is found in the nucleus. It requires a strong energy input to split a proton free from other protons and neutrons. thus, the atoms lose or gain electrons from neighboring ones and become what is known as "ions". Hope it helped!</span>
Sr3(PO4)2 is definitely Ionic
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
