The Rough Endoplasmic Reticulum (rER) The rER is a series of stacked membranes closest to the nucleus that is the site for synthesis and maturation of proteins destined for the plasma membrane, secretory vesicles, or endocytic vesicles. The cytoplasmic surface of the rER contains a protein called the SRP receptor that binds to the SRP, anchoring the ribosome with its growing peptide to the rER membrane

Both proteins are produced in the liver, but LCAT is active in the circulation at the surface of HDL, whereas hepatic lipase resides at the hepatic endothelial cell lining. Mesenteric lymph ducts drain into the thoracic duct, which enters the systemic circulation at the level of the jugular vein.In recent years, it has become appreciated that biliary phospholipid secretion is necessary for proper intestinal chylomicron assembly and thus for secretion of lipid into lymph.Studies in rats with interruption of the enterohepatic circulation by cholestyramine feeding43 or by manipulation of bile composition by dietary means44 revealed an accumulation of lipid in enterocytes
Insulin resistance in adult-onset diabetes is associated with fewer membrane long-chain unsaturated fatty acids due to impaired desaturase and elongase enzyme function. A fatty acid may be defined as an organic acid that occurs in a natural triglyceride and is a monocarboxylic acid ranging in chain length from C4 to about C30 carbon atoms
PICTURE endosymbiosis Theory that attempts to explain the origin of the DNA-containing mitochondria and chloroplasts in early eukaryotes by the engulfing of various types of bacteria that were not digested but became permanent additions to the ancestral "eukaryote". epithelial tissue Cells in animals that are closely packed in either single or multiple layers, and which cover both internal and external surfaces of the animal body

In the amino acid chain, each of the amino acids interacts with the others and it twists like a corkscrew (alpha helix) or it takes the shape of a folded sheet (beta sheet)

Some scientists believe higher concentrations of carbon dioxide and other greenhouse gases will result in an enhancement of the greenhouse effect and global warming. Rain is usually the precipitation type that is formed, and in most cases this moisture is delivered in large amounts over short periods of time in extremely localized areas

This layer is essential for the survival of bacteria in hypotonic environments; loss or damage of this layer destroys the rigidity of the bacterial cell wall, resulting in death. Resistance to the early sulfonamides, for example, was the result of a single amino acid change in the enzyme pteridine synthetase that caused sulfonamides to bind less well than p-aminobenzoic acid

In this chapter, we'll focus on several of the basic functions that cells have in common: creating fuel, manufacturing proteins, transporting materials, and disposing of wastes. As you might imagine, this disease affects virtually every part of the body, causing symptoms like mental retardation, neurological defects, and digestive problems

You know that shirt you're wearing? If it is made of cotton, that's cellulose, too! There can be thousands of glucose subunits in one large molecule of cellulose
Xenobiotic metabolism a series of enzymatic reactions that convert a foreign chemical compound into an inert substance that can be safely excreted from the body. HDL-cholesterol is considered "good cholesterol," because higher blood levels of HDL-cholesterol are associated with lower risk of cardiovascular disease
It is caused by a fatty liver dumping excess bile and cholesterol into the digestive tract as a coping strategy to get rid of the buildup of fatty sludge in your liver. If you take statins and block this self defense mechanism, while continuing to eat too much, your liver will really take a beating and your health will deteriorate regardless of your LDL number
The central core of this molecule, consisting of four fused rings, is shared by all steroids, including estrogen (estradiol), progesterone, corticosteroids such as cortisol (cortisone), aldosterone, testosterone, and Vitamin D. Phospholipids Lecithin Phospholipids are made from glycerol, two fatty acids, and (in place of the third fatty acid) a phosphate group with some other molecule attached to its other end
