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-).
Proteins are linear polymer that are built up of the monomer units called amino acids. There are 20 different amino acid and they are connected by a peptide bond between the carboxyl group and the amino group in a linear chain called a polypeptide. Each protein has different side chains or the R groups.roteins are linear polymer that are built up of the monomer units called amino acids.
