journal of MEMBRANE SCIENCE The journal provides a focal point for ‘‘membranologists’’ and a vehicle for the publication of significant contributions that advance the science and technology of membrane processes and phenomena.The primary emphasis is on the structure and function of non-biological membranes, but papers bridging the gap between non-biological and biological membranes are sought. A broad spectrum of papers is encouraged: • theory of membrane transport • experimental data on membrane

study of Macromolecules in the body is significantly examined through Anatomy and physiology understanding the body at its most primary, fundamental level. Roles carried out by macromolecules are crucial to life contributing to functions throughout the entire body and by understanding these structures and methods, effective medicines to treat conditions can be developed successfully whilst the rest of the body can be grasped. In particular, I have decided to research Protein macromolecules. Proteins

that make up each of these macromolecules while also learning some of their important structural characteristics. This experiment will consist of two parts. The first of which will divide the yeast cells into three of its major macromolecular components: nucleic acids, proteins and polysaccharides. These components are large macromolecules that are quite unique in their composition, structure and function. However, they share a common feature as each macromolecule is composed of repeating subunits

lactase gene. A small change in a DNA nucleotide sequence can have a major effect on the production of a protein and the well-being of an organism. 3. Define macromolecules and list the three categories of macromolecules discussed in this chapter. Macromolecules are any very large complex molecule Three categories of macromolecules: 1) Carbohydrates 2) Proteins 3) Nucleric acids 4. Compare a dehydration reaction to hydrolysis. Dehydration reaction is a chemical reaction

Organic Molecules * Large organic molecules are called macromolecules * Four major categories of macromolecules: 1. Proteins 2. Nucleic Acids 3. Carbohydrates 4. Lipids * Several of these are long chains of smaller subunits. * The smaller subunits are known as monomers * The long chains of monomers are known as polymers * Four groups of Macromolecules * Building Macromolecules – Monomers and Polymers * Molecules, such as amino acids

human body, where the metabolic processes happen to in order to maintain life. It itself is considered a mini-organism made up from organs called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell contains the following organelles (Tracey Greenwood, 2012): the nucleus (which houses the DNA), mitochondria (which produce energy), ribosomes (which make protein), the endoplasmic reticulum (for transportation)
