Photochemistry Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400 - 750 nm) or infrared radiation (750 - 2500 nm).

In a country obsessed with polls and statistics, neither the Department of Defense (DoD) nor anyone else has kept a running count of the number of children raised in the U.S. military over the years.You can't tell just by looking at them.

Biochemistry Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms.By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. The study of the chemistry behind biological processes and the synthesis of biologically active molecules are examples of biochemistry. 2  Genetics is the study of the effect of genetic differences on organisms.

Biochemistry Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. Over the last decades of the 20th century, biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine to genetics are

Pigments Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear colorful. Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths.

- Organic chemists are interested in photochemical preparations of molecules since light can act as a catalyst (or reactant), causing interesting reactions to occur. For example, we have previously discussed the use of ultraviolet light as a catalyst for the formation of radicals in the halogenation of alkanes.
