Lipids are fats that are either absorbed from food or synthesized by the liver. Triglycerides (TGs) and cholesterol contribute most to disease, although all lipids are physiologically important.
Cholesterol is a ubiquitous constituent of cell membranes, steroids, bile acids, and signaling molecules.
Triglycerides primarily store energy in adipocytes and muscle cells.
Lipoproteins are hydrophilic, spherical structures that possess surface proteins (apoproteins, or apolipoproteins) that are cofactors and ligands for lipid-processing enzymes (see table Major Apoproteins and Enzymes Important to Lipid Metabolism). All lipids are hydrophobic and mostly insoluble in blood, so they require transport within lipoproteins. Lipoproteins are classified by size and density (defined as the ratio of lipid to protein) and are important because high levels of low-density lipoproteins (LDL) and low levels of high-density lipoproteins (HDL) are major risk factors for atherosclerotic heart disease.
Dyslipidemia is elevation of plasma cholesterol and/or triglycerides, or a low HDL cholesterol level that contributes to the development of atherosclerosis.

A membrane protein is a protein molecule that is attached to, or associated with the membrane of a cell or an organelle.
More than half of all proteins interact with membranes.
Membrane proteins are proteins that interact with, or are part of, biological membranes. They include integral membrane proteins that are permanently anchored to the membrane and peripheral membrane proteins which are only temporarily attached to the lipid bilayer or to integral proteins.

Aptamers - New Class of Oligonucleotide for Therapeutic and Diagnostic Useajithnandanam
http://technologyinscience.blogspot.com/2014/01/aptamers-new-class-of-oligonucleotide.html
Aptamers are single-stranded RNA or DNA oligonucleotides 15 to 60 base in length that bind with high affinity to specific molecular targets; most aptamers to proteins bind with Kds (equilibrium constant) in the range of 1 pM to 1 nM similar to monoclonal antibodies. These nucleic acid ligands bind to nucleic acid, proteins, small organic compounds, and even entire organisms. Aptamers have many potential uses in intracellular processes studies, medicine and technology. Aptamers are often identified using a technique called SELEX (Systematic Evolution of Ligands by EXponential enrichment). By this techniques aptamers(oligos) having high affinity and specificity to the target is isolated from the sequence pool after several rounds of selection.
Being Part of the Medical Field as a Medical Technologistliceo01
Medical technologists do quite a wide variety of medical tests depending on the doctor’s prescription or order, ranging from hematology tests to hormone assays. Here are a few examples of these said tests and what they are usually for: - http://www.liceo.edu.ph
