What are some identifiers for the c peptide?

The connecting peptide, or C-peptide, is a short 31-amino-acid protein that connects insulin's A-chain to its B-chain in the proinsulin molecule. In the insulin synthesis pathway, first preproinsulin is secreted from the beta cells of the pancreas with an A-chain, a C-peptide, a B-chain, and a signal sequence. The signal sequence is cleaved from the N-terminus of the peptide by a signal peptidase, leaving proinsulin. Then the C-peptide is removed, leaving the A-chain and B-chain that constitute the insulin molecule.


What is the difference between a cis and trans peptide bond?

A cis peptide bond occurs when the two amino acids in a peptide chain are on the same side of the peptide bond, while a trans peptide bond occurs when the two amino acids are on opposite sides of the peptide bond. This difference in orientation can affect the overall structure and function of the protein.

What is the difference between multichannel and multidimensional signals?

if a signal is a function of single independent variable,then signal is called multichannel signal. if a signal is function of multiple independent variable then signal is called multidimensional signal.

What is the significance of a trans peptide bond in protein structure and function?

A trans peptide bond in protein structure is significant because it affects the protein's overall shape and stability. It can influence how the protein folds and interacts with other molecules, ultimately impacting its function in the body.


What is The bond that links two amino acids called?

This is called a peptide bond, or peptide linkage.


What is the first signal required for activation of a T cell?

The first signal required to activate a T cell is MHC(Major Histocompatibility Complex) presenting an antigen(foreign peptide) to the T cell receptor.


Is impulse function is an energy signal or a power signal or both Explain?

Is exponential signal an energy signal or power signal?

If the signal is not bounded by a step function, then an exponential signal is neither a power nor an energy signal. So the answer is neither.

Detector converts optical signal to electric signal


How might placing a peptide into a non-polar solution affect the tertiary structure of the peptide?

Placing a peptide into a non-polar solution can disrupt its tertiary structure, as non-polar solvents can disrupt hydrogen bonding and hydrophobic interactions that stabilize the structure. This disruption can lead to the unfolding or denaturation of the peptide, altering its overall shape and function.
