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-).
More specifically, peptide bonds join the carboxyl group of one amino acid with the amino group of another. For example, the amino acid called glycine can bond with the amino acid called alanine to form a dipeptide. The prefix 'di' means two, so, a dipeptide is defined as a compound consisting of two amino acids.
