What is the C-terminal amino acid in the tetrapeptide
Val-Thr-Phe-Pro?
O threonine
O phenylaline
O valine
O proline


Sagot :

The C-terminal amino acid in the tetrapeptide is valine.

Valine is one of three branched-chain amino acids that enhance energy, increase endurance, and aid in muscle tissue recovery and repair. This group also lowers elevated blood sugar levels and increases growth hormone production.

The cease with a free carboxyl group is called the C-terminal amino acid residue. Peptides are named from the N-terminal acid residue to the C-terminal amino acid.

The C-terminal amino acid may be decided by way of addition of carboxypeptidases, enzymes which cleave amino acids from the C-terminal. A time direction ought to be carried out to look which amino acid is launched first.
