Dehydration synthesis
During protein synthesis, the amino acids are linked together by peptide bonds. This process is carried out by the ribosomes.
aminoacyl-tRNA synthetase
When monosaccharides are joined together by dehydration synthesis then it is called glycosidic linkage, it is a covalent bond. When lipids are being bonded together the bond is called an ester bond. When amino acids are joining together to form a polypeptide then the bonds are called peptide bonds.

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.
prohormones. These prohormones are inactive and need to be cleaved or modified to become biologically active peptide hormones.

Peptide bonds
Dehydration synthesis is the process that produces peptide bonds. A peptide bond is a covalent chemical bond formed between a carboxyl group and an amino group.
Peptidyl transferase is the enzyme that catalyzes the formation of peptide bonds between amino acids during translation of protein synthesis.
