Stake attention in this memory
The image displays two chemical structures of amino acids, side-by-side, on a white sheet of paper. Above the structures, the question "Which Form Occurs in Water ?" is printed. The left structure is labeled "Nonionic form" and shows a molecule with an -OH group attached to a carboxyl group (C=O), and an -NH2 group. The right structure is labeled "Zwitterionic form" and depicts a molecule where the carboxyl group has lost a proton, becoming -COO-, and the amino group has gained a proton, becoming -NH3+. Both structures have a central carbon atom bonded to a hydrogen atom and an 'R' group, representing the side chain of the amino acid. The background of the image is a textured, tan surface that appears to be a wall or floor. There are no people visible in the image. The image was taken indoors or in a shaded outdoor area. There is no information in the image that would indicate its location in Jalingo, Nigeria.
