In international law, statelessness is the lack of citizenship. A stateless person is someone who is not considered as a national by any state under the operation of its law.[2] Some stateless persons are also refugees. However, not all refugees are stateless, and many persons who are stateless have never crossed an international border.[3]
Most of the polyphenols in green tea are flavan-3-ols (catechins). The phenolic content in tea refers to the phenols and polyphenols, natural plant compounds which are found in tea.These chemical compounds affect the flavor and mouthfeel and are speculated to provide potential health benefits.Polyphenols in tea include catechins, theaflavins, tannins, and flavonoids.Polyphenols found in green tea include but are not limited to epigallocatechin gallate (EGCG) , epigallocatechin, epicatechin gallate, and epicatechin; flavanols such as kaempferol, quercetin, and myricitin are also found in green tea.he phenolic content in tea refers to the phenols and polyphenols, natural plant compounds which are found in tea. These chemical compounds affect the flavor and mouthfeel and are speculated to provide potential health benefits.
Polyphenols are also found in animals. In arthropods such as insects and crustaceans polyphenols play a role in epicuticle hardening (sclerotization). The hardening of the cuticle is due to the presence of a polyphenol oxidase.In crustaceans, there is a second oxidase activity leading to cuticle pigmentation.he term polyphenol should be used to define compounds exclusively derived from the shikimate / phenylpropanoid and/or the polyketide pathway, featuring more than one phenolic unit and deprived of nitrogen-based functions.
