Metabolism Figure 1 above is adapted from João M‚ et al (2012) the chromatographic methodologies for analysis of cocaine and its metabolites which‚ shows the metabolic pathway of cocaine administrated. Cocaine is largely metabolized into two major metabolites benzoylecgonine (BE) and ecgonine methyl ester (EME) and two minor metabolites norcocaine (NCOC) and m- and p-hydroxycocaine (OH-COC) (Goldstein et al.‚ 2009). Benzoylecgonine is primarily produce in the liver by human carbozylerstrase type

AS Biology - Unit 1 ------------------------------------------------- Metabolism Metabolism is a term to describe all reaction which is taking place within a cell and is separated into two types which are * anabolic = compounds being built up * catabolic = compounds being broken down ------------------------------------------------- Water The water molecule is a molecule which is made up from 2 hydrogen atoms and 1 oxygen atom. It is bounded by 2 covalent bonds and has is polar.

INTRODUCTION: Bioactive vitamin D or calcitriol is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus‚ and in mineralization of bone. More recently‚ it has become clear that receptors for vitamin D are present in a wide variety of cells‚ and that this hormone has biologic effects which extend far beyond control of mineral metabolism. Vitamin D is thus not a true vitamin‚ as it can be synthesized in adequate amounts

critical for normal function of the thyroid gland‚ which is a key regulator of the body’s basic metabolic rate. Iodine is a micronutrient‚ meaning we require only small amounts of it. For example‚ adults need about 150 micrograms of iodine in the form of iodide ion per day. However‚ an insufficient supply of iodide via diet and drinking water causes the non-cancerous enlargement of the thyroid gland known as goiter. Prolonged lack of iodide can lead to loss of thyroid function and the birth defect known

When you hear metabolism the first thing you might think of is the number of calories your cells burn each day. Metabolism is actually the sum of all chemical reactions that take place in the body. Metabolic reactions that produce energy are dependent on the cardiovascular system‚ which send oxygen to all the cells in your body. Although metabolism is not primarily made of reactions that burn nutrients like carbohydrates‚ fats and protein‚ these are perhaps the most widely known of the metabolic

The results of my prediction were the same. 3. Explain why a change in extracellular Na+ did not alter the membrane potential in the resting neuron. There are less Na+ leak channels than K+ leak channels‚ and more of the K+ channels are open. 4. Discuss the relative permeability of the membrane to Na+ and K+ in a resting neuron. Membrane permeability to Na+ is very low because there are only a few Na+ leak channels. The membrane is more permeable to K+ because of the higher number of K+ leak

19 signs your thyroid isn’t working right By Anne Krueger Published August 29‚ 2013 Health.com The thyroid‚ a butterfly-shaped gland in the neck‚ can have a dramatic impact on a huge variety of bodily functions‚ and if you’re a woman over 35 your odds of a thyroid disorder are high—more than 30 percent‚ by some estimates. At least 30 million Americans have a thyroid disorder and half—15 million—are silent sufferers who are undiagnosed‚ according to The American Association of Clinical
