Colostrum, the yellowish, sticky breast milk produced at the end of pregnancy, is recommended by WHO as the perfect food for the newborn, and feeding should be initiated within the first hour after birth.
The plasma membrane is a fluid mosaic. This means that it is flexible and made up of many different types of molecules. Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for
The Fluid Mosaic Model [edit]. The fluid mosaic model was originally proposed by S. Jonathan Singer and Garth Nicolson in 1972. Their idea of this model was to show and describe the general structure of a biological membrane.Biological membrane is composed of a lipid bilayer  that is essentially a two-dimensional solution composed of lipids and proteins.o break down each part of the name of the model: The fluidity of the model is based on the hydrophobic components like proteins and lipids. These two components allow for the membrane to have a fluid motion since it is not solid; it is not made of only one type of macromolecule.
