Long before a deeper understanding of their numerous biological functions, the plant lectins, also known as phytohemagglutinins, were noted for their particular high specificity for foreign glycoconjugates (e.g. those of fungi, invertebrates, and animals). and used in biomedicine for blood cell testing and in biochemistry for fractionation.
Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves. Radar waves. Heat (infrared radiation) Light.
Most simply put, radiation is energy that travels through space as either waves or high speed particles. There are two types of radiation: non-ionizing radiation and ionizing radiation. Together these two types of radiation form the electromagnetic spectrum, shown below in Figure 1.he electromagnetic spectrum, marked off above in various frequency (Hz) ranges, is composed of non-ionizing radiation and ionizing radiation. We spend most of our lives being constantly, and safely, exposed to many types of radiation including radio waves, microwaves, and visible light. (OSHA, 2011).
