Answer:
All annelids and arthropods have a body plan. Unlike annelids, arthropods also have a coelom, and a segmented body. The circulatory system of annelids is closed, while the circulatory system of arthropods is opened.
Explanation:
Why am I slightly threatened by this?
Answer:
Alanine is obtained as the first amino acid, taking into account that the reaction with the Sanger reagent hydrolyzes N- (2,4-dinitrophenyl) alanine. thus with the fragments of the partial hydrolysis they are organized to create a polypetidic chain
ala-asp-gly-ala
gly-ala-phe
phe-be-wing
be-wing-phe-asp
We obtain that the correct sequence of the peptide is "ala-asp-gly-ala-phe-ser-ala-phe-asp"
That's called a convex lens, as they converge.
The statement 'interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane' explains why protein folding is critical. This process is fundamental for the function of transmembrane proteins.
Protein folding refers to the process by which a polypeptide (i.e., a protein) adopts its final tridimensional 3D shape (conformation).
In a protein, some amino acids contain hydrophilic R groups, whereas other amino acids contain hydrophobic R groups.
During protein folding, hydrophobic amino acids are arranged so they can interact with the long chains of the fatty acids in the internal region of the lipid bilayer, whereas hydrophilic amino acids are arranged so they interact with water on the surface of the cell membrane.
