Carboxylic acid is organic chemical compound that contain a functional group that is carboxyl group –COOH which is made of hydroxyl group and carbonyl group both attached to the same carbon which is attached to hydrogen atom or alkyl group thus the general formula of the carboxylic acid is R–COOH with R represent alkyl group or a hydrogen atom. Carboxylic acid functional group is partly ionized in solution so it is a weak acid, however it's acidity is considered as the chef chemical characteristic of it as it is generally more acidic than the other organic compounds that contain hydroxyl group and more acidic than the common organic functional groups but it is generally weaker than the common mineral acids such as hydrochloric acid (HCl).
Erythritol which fall under the category of sugar alcohol is 60-80 times as sweet as sucrose and it contains almost zero calories. It has been approved for the use of food additives in the United States and many other countries as studies have shown that erythritol is safe for human consumption even on a daily basis and at a high amounts. It will not cause an increase in blood sugar, tooth decay and digestive upsets even consumed at a small quantities. 90% of Erythritol being consumed is being absorbed into small intestine and travelled into the bloodstream and excreted in the urine. The 10% left will enters the colon.
Apart from these A.fumigatus produces various toxic metabolites like Verruculogen, Pseurotin, Sulochrin, asterric acid, trypacidin, fumiquinazolins. Verruculogen is a potent tremorgen and is capable of modifying the electrophysical properties of the human nasal epithelial cells. Pseurotin A inhibits immunoglobulin E function
Mycotoxin is naturally occurring secondary metabolite of toxic in low concentration and low molecular weight (MW <700) (Sorriano,2007; Haschek & Voss, 2013). Several fungal species of the Alternaria genus are known producers of mycotoxins. Some of the powerful Alternaria toxins have been implicated in a variety of adverse health effects.
Naproxen (Naprosyn) is a nonsteroidal anti-inflammatory drug (NSAIDs) used to treat joint pain. M.H. was previously prescribed Naproxen to reduce the bilateral wrist pain and associated inflammation. Naproxen is mainly used to reduce inflammation, stiffness, and pain. NSAIDs block the formation of prostaglandins. Prostaglandins are involved in the body’s normal function and inflammatory response. Proteins, Cox-1 and Cox-2, control these prostaglandins. Cox-1 controls the formation of the prostaglandins involved in the normal function of the body’s organs. Cox-2 controls the formation of the prostaglandins involved in the body’s inflammatory response. By preventing the body from producing prostaglandins, NSAIDs reduce swelling and pain.
Following the instructions from the Biofuel Enzyme Kit, we performed a baseline experiment in which all factors remained constant except time in order to establish a control for absorbance and concentrations of p-nitrophenol. We then used this information to determine the Vo and the other concentrations in order to form a graph. On a molecular level, since the temperature, pH, inhibitor,
0.01 g of phenyl red was weighed out and put it in the test tube and also 1 mL of buffer was added to the test tube. It will form a yellow color as indicated it is acidic. So after the buffer run through the column and reach the surface of the column bed, we labeled 16 cuvettes and from 1-16 with 1 was used for blank.
1,4-disubstitution pattern, the diequatorial which is the most stable arrangement is known as the "trans" isomer. One substituent is "slant up" while the other one is "slant down". Chair flipping causes the methyl substituents to be in a conformation that is anti to each other. This results in a less stable conformation since it possesses two axial substituents.
The first portion of the lab was about preparing the standard curve for the reaction products. In this part we already know the concentration of the product, Nitrophenol. So, to perform this we took six test-tubes and filled each with 1ml of standard labeled with S1-S6 respectively. For example 1st =S1, 2nd=S2, 3rd =S3 and so on. After that we measured the absorbance of each test tubes setting the first one as blank. And the data is recorded in the table (5.1). After recording the reading we constructed a Nitrophenol Standard curve by plotting A410 on y-axis and concentration on the x-axis as on figure (5.2). The second portion require us to prepare acid phosphatase from the wheat germ extract. But, this part of the lab was already
To begin with, a chemical reaction is a rearrangement of atoms when bonds are broken in the reactants and new ones form which are the products. Atoms cannot be lost, changed, or gained in identity. For example, when hydrogen and oxygen are put together, they make water (Shipman, 2014). The chemical reaction known as oxidation is when oxygen, a very reactive element, combines with many substances in a reaction (Cobb, 1972). This reaction occurs in many fruits, especially apples because they contain a vast amount of an enzyme known as polyphenol oxidase (Gritzer, 2015).
In the last decades sucrose esters have attracted considerable interest by researchers, due to the vast applicability of these products in several industrial areas, such as in plant tissue culture , in cosmetic formulation to make most of the high-performance ingredients , in formulations of banana aroma in food and beverage flavoring industry , in microemulsion for synthesis of WO3 in nanoscale , in inhibition of bacterial growth such as inhibition of Streptococcus sobrinus for application in oral-hygiene products aimed at disrupting plaque formation and preventing caries . Despite these interesting applications, sugar esters present much more important applications in advanced technologies, such as in nanomedicine and in cancer
In the United States, The Food and Drug Administration has the power to decide what is and is not safe to be consumed by the human body. The pharmaceutical industry makes billions a year, they develop, design, add chemicals to, and produce hundreds of new drugs a year. It has been argued by many scientists, economists, and average american citizens that the FDA regulates and approves of drugs based on biased opinions and for reasons other than the health of consumers.
This paper will review the correlation between the use of anabolic drugs and the psychological impact of those who use them. This will be a compilation of of research taken from other studies using both human participants and key information gathered from each online publication in regards to the topic. According to the U.S. National Library of Medicine, National Institutes of Health, and the National Center for Biotechnology Information,“Inappropriate use of anabolic androgenic substances (AAS) was originally a problem among athletes but AAS are now often used in nonsport situations and by patients attending regular addiction clinics.” This paper will examine Kurt Skårberg, Fred Nyberg, and Ingemar Engströms research in conjunction
