Polyphenols contained in teas are classified as catechins. Green tea contains six primary catechin compounds: catechin, gallaogatechin, epicatechin, epigallocatechin, epicatechin gallate, and apigallocatechin gallate (also known as EGCG).ea has been cultivated for centuries, beginning in India and China. Today, tea is the most widely-consumed beverage in the world, second only to water. Hundreds of millions of people drink tea, and studies suggest that green tea (Camellia sinesis) in particular has many health benefits.
An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.rbitals are given names in the form: where X is the energy level corresponding to the principal quantum number n, type is a lower-case letter denoting the shape or subshell of the orbital and it corresponds to the angular quantum number â, and y is the number of electrons in that orbital.
This article is about the orbit, the anatomical space that contains the eye. For other uses of orbit or orbita see Orbit (disambiguation) and Orbita (disambiguation) .In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated.Orbit can refer to the bony socket, or it can also be used to imply the contents. In the adult human, the volume of the orbit is 30 mL, of which the eye occupies 6.5 mL.he orbits are conical or four-sided pyramidal cavities, which open into the midline of the face and point back into the head. Each consists of a base, an apex and four walls. There are two important foramina, or windows, two important fissures, or grooves, and one canal surrounding the globe in the orbit.
