CHEMISTRY GLOSSARY
T-S diagram → T-S dijagram
The relationship between the temperature (T) and the salinity (S) of a seawater can be illustrated graphically on a T-S diagram, which is a simple, but powerful tool used in studies of seawater density, mixing, and circulation. In a T-S diagram, temperature is plotted along the vertical axis in degrees Celsius and salinity is measured along the horizontal axis in PSU (Practical Salinity Units). Seawater density is illustrated in the diagram by curved lines of constant density (isopycnals). Water tends to move horizontally throughout the deep ocean, moving along lines of equal density.
Chitin → Hitin
Chitin is a nitrogen-containing linear polysaccharide of ß(1->4) linked units of N-acetyl-ß-d-glucosamine. The structure of chitin is similar to cellulose except for the replacement hydroxyl group (-OH) at the carbon 2 with an acetyl amine group (–NH–CO–CH3). Chitin is the main component of the exoskeleton, or outer covering of insects, crustaceans, and arachnids. It is also found in the cell walls of certain fungi and algae. After cellulose, chitin is the second most abundant biopolymer in nature. It is insoluble in water, organic solvents, weak acids and lyes.
