Although legalization activists and many marijuana users believe smoking pot has no negative effects, scientific research indicates that marijuana use can cause many different health problems. Marijuana is the most commonly used illicit drug in the United States.
A peptide bond (amide bond) is a covalent chemical bond formed between two amino acid molecules.ne loses a hydrogen and oxygen from its carboxyl group (COOH) and the other loses a hydrogen from its amino group (NH 2). This reaction produces a molecule of water (H 2 O) and two amino acids joined by a peptide bond (-CO-NH-).
Building a polypeptide: As we noted for nucleic acids, a polymer is a chain of subunits, monomers, linked together by chemical bonds. The bond between two amino acids is known as a peptide bond. Two amino acids, joined together by a peptide bond, is known as a dipeptide.An amino acid polymer is known as a polypeptide.s we noted for nucleic acids, a polymer is a chain of subunits, monomers, linked together by chemical bonds.
