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.

A covalent bond between two amino acids is a peptide bond.
A nitrogen atom in an amino group and a carbon atom in a carboxyl group
C-PEPTIDE test costs around $100 USD so you plus $20 or minus $20
Yes they is different, C language are case-sensitive.

C, o, u, e
Identifiers are a bit more generic in the context of programming. If you mean, in terms of the C languages (C, C++, C#), the question is the reverse...keywords may NOT be used as identifiers. For example, you cannot use keywords such as "int", "float", "double", etc. as the names of variables or objects.

A beta-peptide is any form of artificial peptide made from beta-amino acids, used in some antibiotics as an attempt to counter resistance.
