INTRODUCTION Lovastatin is a statin drug that decreases the total cholesterol level in patients diagnosed with hypercholesterolemia. The drug aims to prevent serious cardiovascular diseases such as heart attack due to blockage of arteries. Lovastatin acts as a competitive inhibitor for the HMG-CoA reductase enzyme in catalyzing the conversion of HMG-CoA to mevalonate, (Alberts, 1998). The drug is also hydrolyzes in vivo to active form β-hydroxyl acid, (Katz, 2005) and was recently researched on…

The sulfide production test was also used to find out the identity of the unknown bacteria. When amino acids cysteine and methionine are decomposed, they produce hydrogen sulfide gas. Certain bacteria produce the enzymes necessary to break down those two amino acids and a simple stab test can be done to see if the bacterium is present. A sulfite indole motility medium is utilized…

But, in contrast to other environmental resources like healthcare and education, nutrition can directly modify gene structure and facilitate genetic factors by providing the specific molecules that enable genes to exert their potential or targeted effects on brain growth and development. The brain is a specialized tissue that depends upon the generation of electrical potentials and their conduction through long axonal components of cell-bodies and through the synaptic gaps between these…

BIOMOLECULES It is from the foods we eat that we get the essential compounds that our body needs. These types of compounds are used by our body for energy and growth. In this chapter, you will learn about biomolecules and their functions in the human body. iEngage Nutrition Facts Objectives To examine nutrition facts from food labels To recognize the importance of knowing the food labels Materials food label paper pen Procedures 1. Examine carefully the nutrition facts of…

source as the levels of essential amino acids meet the FAO/WHO requirements of dietary proteins and exceed the levels in soybean protein, corresponding to 36% of total amino acids (Galland-Irmouli et al., 1999). While lysine, threonine, tryptophan, methionine and cysteine are present in comparatively lower levels, Holdt and Kraan (2011) concluded that their quantities are still higher than those found in terrestrial plants. Lourenço et al. (2002) reported that the levels of isoleucine and…

Arsenic contamination and possible remediation Victoria Reyes Texas A&M International University Abstract Arsenic can be found in many places on Earth. This includes from natural sources and as a by-product from different anthropogenic activities. The fact that arsenic can be found so commonly on Earth has lead to the contamination of several countries’ drinking water. This has put many people at risk for arsenic poisoning. There are many complications that come from the continuous ingestion…

Describe Mendel's P, F1, and F2 generations in his experiments with pea plants. Student Answer: Mendel's F1 generation, also known as the first filial generation is the parent of the offspring generation which is the F2 generation(Daempfle,2016). The P generation is the also known as the parent generation. The parent…

CHAPTER 1 INTRODUCTION 1.1 TUBERCULOSIS Tuberculosis (TB) is an infectious disease caused by the bacillus Mycobacterium tuberculosis. TB is a major global health problem and it ranks alongside Human Immunodeficiency Virus (HIV) as a leading cause of death worldwide. According to the estimates of WHO global tuberculosis report of 2015, there were 9.6 million people who developed TB and 1.5 million who died from the disease in 2014. 1.2 TRANSMISSION AND PATHOGENESIS OF TB TB infection occurs when…

The individual roles of vitamin B12 also essential for human beings. Vitamin B12 can maintain myelin sheath, promote normal growth of nerve cells, and be involved in bone cell metabolism/activity. Vitamin B12 and folic acid reduce homocysteine to methionine, which is then converted into S-adenosylmethionine (SAM), a crucial co-factor for 150+ methyltransferases including glycine n-methyltransferase (GNMT) in the one carbon pathway.(Mitchell, Conus, and Kaput, 2014). Therefore, High levels of…

The benefits of a vegetarian diet are most evident among Seventh-Day Adventists. A systematic review and meta-analysis was done that compared vegetarian diet, Seventh Day Adventists and the risk of cardiovascular mortality. Eight studies combined equated to 183,321 participants. The 3 Adventist cohorts revealed significant relations between vegetarian diet and reduced all-cause mortality, whereas the non-Adventist studies failed to show any reduction in mortality in vegetarians. Likewise…
