Cyclic peptides are polypeptide chains which contain a circular sequence of bonds. This can be through a connection between the amino and carboxyl ends of the peptide, for example in cyclosporin; a connection between the amino end and a side chain, for example in bacitracin; the carboxyl end and a side chain, for example in colistin; or two side chains or more complicated arrangements, for example in amanitin.

In mathematics, a cyclic order is a way to arrange a set of objects in a circle. Unlike most structures in order theory, a cyclic order is not modeled as a binary relation, such as "".

n. anything that is owned by a person or entity. Property is divided into two types: "real property," which is any interest in land, real estate, growing plants or the improvements on it, and "personal property" (sometimes called "personalty"), which is everything else. "Common property" is ownership by more than one person of the same possession. "Community property" is a form of joint ownership between husband and wife recognized in several states. "Separate property" is property owned by one spouse only in a community property state, or a married woman's sole ownership in some states. "Public property" refers to ownership by a governmental body such as the federal, state, county or city governments or their agencies (e.g. school or redevelopment districts). The government and the courts are obligated to protect property rights and to help clarify ownership.
