Histidine

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 threonine in Palmaria palmata are comparable to levels found in legumes, while histidine in Ulva pertusa is present at levels similar to those in albumin. Both aspartic and glutamic acids constitute a large proportion of the amino acid fraction in seaweeds compared to soybeans and eggs, with glutamic acid being the most abundant…

Since acetic acid is considered a weak acid (strong within the scale of weak acids), there is a range at which the acetic acid and acetate will form a stable buffer. Using the Henderson-Hasselbalch equation for buffers, it’s possible to calculate the pH based on the ratio of acid to conjugate base, or calculate the ratio given the pH and pKa value. Finding charge on a protonated amine: The pKa value given for the amino group on any amino acid specifically refers to the equilibrium between the…

roduction In my report I plan Identify and discuss the following Carbohydrate Fats Vitamins Protein Minerals Water Fibre Discussing structure the needs and food sources. nutrition is a key part of life and to have a good balance of diet will mean healthy living and good long life Carbohydrate Roles within the Body, Carbohydrate is the main food source for the body, it provides energy/fuel for physical activity, organ function and brain function also a energy storage compound and components…

A second replication will then cause the new guanine to pair with cytosine. This is a transition mutation. 18. The Ames Test is used to determine potential carcinogenic effects of chemicals. This test uses S. typhimurium that cannot synthesize histidine. Mutagens are then added that causes missense or frameshift to fix the mutation and allow it to grow. 19. MutT is important because it helps in the degradation of base 8-Oxo-dGTP (oxoG). The base oxoG is able to form pairs with C and A. Cells…

We determined that the UV light treatment was the most potent treatment of mutagenesis and also the most effective in inducing mutations, followed by the Tn5 and the EMS was the least potent and effective treatment. Introduction A culture of E.coli K12, KL14 was used to carry out the experiment on. The advantage of using E.coli cells to experiment on is that they are haploid organisms and contain a single set of chromosomes so if a mutation was to occur, the bacterial cell will express it as…

papillomavirus (Basu). The vaccine does not contain any of the virus itself or DNA of HPV in the Gardasil vaccine, so it cannot cause any HPV- related illness or cancer. The Gardasil vaccine contains “aluminium, Sodium Chloride (salt), water, L-histidine, Polysorbate 80 and Borax, to stimulate the immune system and keep the vaccine stable and suitable for injection” (“How Does the HPV Vaccine Work?”). The vaccine is made by tiny proteins that look like the outside of the HPV virus. If the body…

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…

Inborn errors of metabolism are a group of rare disorders characterized by metabolic pathway abnormalities. One such disorder is Maple Syrup Urine Disease (MSUD) otherwise known as Branched-chain Ketoaciduria, a dangerous condition in which over saturation of amino acids in the blood can lead to toxicity progressing to encephalopathy, neurodegeneration, coma or respiratory failure (Haldeman-Englert, 2015). MSUD results from a malfunction of the branched-chain alpha-ketoacid dehydrogenase complex…
