are not just critical to structural formation‚ but they also store molecules called growth factors and release them at various times to control the growth and repair of tissues and organs throughout the body. Production of abnormal fibrillin-1 monomers from the mutated gene disrupts the formation of multiple polymers of fibrillin-1 and prevents microfibril formation. This pathogenetic mechanism has been termed dominant-negative because the mutated fibrillin-1 disrupts microfibril formation though

Background -Hemophilia A is an inherited disorder in which one of the proteins needed to form blood clots is missing or reduced. This lacking protein is known as blood clotting factor 8. Without F8‚ the blood cannot clot properly to stop bleeding and can result in excessive bleeding or disabilities. Hemophilia A -When blood is not able to clot and allow wounds to heal‚ this is a result of Hemophilia A Symptoms Include: -Prolonged bleeding from cuts -Excessive nose bleeds -Many large

Organic molecules are those primarily made up of carbon‚ hydrogen and oxygen. The common organic compounds of living organisms are carbohydrates‚ proteins‚ lipids‚ and nucleic acids. Each of these macromolecules (polymers) are made of smaller subunits (monomers). The bonds between these subunits are formed by dehydration synthesis. This process requires energy; a molecule of water is removed (dehydration) and a covalent bond is formed between the subunits . Breaking this bond is called hydrolysis; it requires

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

CHAPTER 1 INTRODUCTION 1.1 PRELIMINERIES Due to highly development of chemical and biochemical industries‚ acetic acid has largely produced to fulfil the needs of world demand in production of daily used products and for pharmaceutical needs. Therefore‚ this study is carried out to introduce the production of acetic acid using biological pathways which includes the used of microorganisms. In this chapter will briefly explained on the knowledge about acetic acid and the microorganism

Molecules of carbohydrates and fats consist of carbon‚ hydrogen‚ and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose‚ fructose‚ galactose) to complex polysaccharides (starch). Fats are triglycerides‚ made of assorted fatty acid monomers bound to glycerolbackbone. Some fatty acids‚ but not all‚ are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon‚ oxygen‚ and
