Each year Colorado Counties are required to submit to the Division of Property Taxation, the Property Tax Administrator, the State Board of Equalization and the County Board of Equalization (the Board of County Commissioners) an Abstract of Assessment.
Nageli and Cramer in 1855 had already suggested that biological cells are separated from their environment by a membrane possessing special characteristics, and in 1900 Overton performed some simple but classical experiments which proposed that cell membranes were composed of lipids (1).
Phospholipids, the type of lipid that makes up the majority of lipids found in the cell membrane, are made up from a phosphate head (circles) that likes water and a fatty-acid, or lipid, tail (lines) that hates it.ut the membrane is a border, as well as a wall â what should be inside and outside the cell is always changing, and the lipids help to regulate this traffic. The principle behind lipid membranes' powers of self-assembly is so simple, it has become proverbial â oil and water do not mix.
