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-).
Explain how a peptide bond forms between two amino acids. A peptide bond links the carboxyl group of one amino acid with the amino group. List and describe the three major components of an amino acid. Explain amino acids may be grouped according to the physical and chemical properties of the R group. At the pH in a cell, the amino and carboxyl groups are usually ionized.
