The bonds that hold the two chains of an insulin molecule together are?
The bonds that hold the two chains of an insulin molecule together are disulfide bonds. These bonds form between cysteine amino acid residues in the A and B chains of the insulin molecule, creating a stable structure essential for its biological function.
What is the hydrophobic or hydrophilic areas of insulin?
Insulin is a hydrophilic hormone with hydrophobic regions located within its structure. The hydrophilic portions of insulin enable it to dissolve in the bloodstream, facilitating its transport to target cells. The hydrophobic areas tend to have nonpolar amino acid residues and are important for the stability and structure of the insulin molecule.
What functional groups are found in insulin?
Insulin contains a peptide functional group due to its protein structure. Additionally, it contains amino acid residues that contribute to its biological activity and role in controlling blood sugar levels.
How do the amino acid side chain residues in an helix orient themselves in relation to the center of the helix?
The amino acid side chain residues in an helix orient themselves outward from the center of the helix.
Where is an amino acid attached to a tRNA molecule?
An amino acid is attached to a tRNA molecule at the 3' end.
What amino acid residues are found in abundance in casein?
If not mistaken, it is proline.
How is depeptides formed?
a peptide composed of two amino-acid residues.
How is depeptide bond form?
a peptide composed of two amino-acid residues.
How many amino acid is present in lysozyme?
129 aa residues long
A polypeptide can best be described as?
Short sequence of amino acids. Insulin is a polypeptide of about 53 [amino-acid] residues; it is like Pluto - is it a protein or not?
Molecule that carries amino acids to the ribosomes for incorporation into a protein?
The molecule that carries amino acids to the ribosome is transfer ribonucleic acid, or tRNA. Each tRNA molecule is specific to the amino acid it carries.
Where exactly does an amino acid link to a tRNA molecule?
An amino acid links to the tRNA molecule at the binding site called the "aminoacyl site" (A-site) on the tRNA molecule. This process is catalyzed by an enzyme called aminoacyl-tRNA synthetase, which ensures the accurate pairing of the correct amino acid with its corresponding tRNA molecule.
