Essential amino acid

explanation of how genetic information flows as it is passed from DNA to RNA to protein. DNA replicates and converts the information it carries into RNA, this process is called transcription. During transcription the information is passed through nucleic acids and there is no need for a change in the “language.” When RNA continues the flow of information and it is passed to proteins, this is called translation. It is called translation because the information must be translated, and this is…

Prokaryotes There are two types of organisms based cell types: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into two parts: Bacteria and Archaea. Prokaryotes are much smaller than eukaryotes. Prokaryotes contain a single loop of chromosomal DNA which is stored in nucleoid. Eukaryotes DNA is found on tightly bound and organised chromosomes. Genetic expression is the process where genotypes coded in the genes are displayed by the phenotypes of the individuals. The DNA is then copied…

As briefly mentioned before, atropine acts as an antagonist on acetylcholine because its chemical structure is similar to acetylcholine. Thus, structure is an important feature of the atropine molecule that is imperative to understanding its effects on the body. Although today’s chemists know the chemical structure of atropine, the conformational flexibility of the molecule is still poorly understood. A conformation is any three-dimensional arrangement of atoms within a molecule that results…

1. Most aquaporins have a similar structural arrangement, consisting of a similar fold. This fold contains helices encasing a small water-conducting channel where water is able to arrange in a singular line. There are cytoplasmic and extracellular loops immersing into the membrane through opposing sides, and form two smaller helices creating a psedo transmembrane segment. Within the membrane, there are four aquaporin molecules forming a homo-tetramer, creating a fifth channel; the channel is…

workouts are not the only challenges one has to beat while taking on a weight loss program. Taking control over hormonal changes namely hunger and cravings, while maintaining muscular strength, is the actual challenge. Lately, BCAA (branched-chain amino acid) supplements have made a predicted comeback to fitness groups, which crave a leaner body and with fat loss. Extensive research, studies and experiments have been conducted that support the utilization of BCAAs than most different supplements…

bonded sequences of amino acids and this happens through dehydration synthesis where complex molecules are broken down to simple components. Secondary structure happens within the protein and can repeat multiple times and this happens from the folds by the Hydrogen bonds. Finally, you reach tertiary structure where the final 3-dimensional shape is shown by the complete polypeptide chain. This is also where the R group interactions take place and with Huntington’s, the amino acid glutamine is…

Discussion: The specific purpose for this study was to see how enzyme activity would change as there was a change in temperature and pH. Both temperature and pH were hypothesized to have an affect on enzyme activity. Each had an optimal temperature. At this point, the rate of enzyme activity would stop increasing and begin to decrease. For temperature, it was hypothesized that the optimal temperature would be 48°C. For pH, it was hypothesized that the optimal pH would be 7. As temperature was…

S.aureus can be sensitized to B-lactams by preventing WTA biosynthesis through inactivation of TarO, which catalyses the first step of the WTA pathway(Maki,Campbell). This identified WTA biosynthesis as an attractive target for novel strategies to treat MRSA. WTAs are structurally diverse anionic polymers covalently attached to PG(Vollmer,Swoboda) and in S.aureus consist of a polyribitol-phosphate backbone of 11-40 repeating units(Xia10) decorated with three tailoring modifications:…

tentacles of various squid.” SRT protein is comprised of various amino acids, three of which are glycine, histidine, and tyrosine. Glycine and histidine comprise 40-50% of the total amount of amino acids in the ring teeth. Glycine provides the SRT protein with a rubberlike elasticity, and histidine is an important component in load-bearing and impact resistance tissues. The amino acid tyrosine makes up about 10-15% of the amino acids in an SRT protein, and the hydroxy group on tyrosine allows…

1.10. Uses of Lactic acid Lactic acid and some of its derivatives (salts and esters) are used in three main applications: foods, polymers, and industrial. Figure 2: Uses of lactic acid [22] 1.10.1. Food The food industry is the traditional large consumer of lactic acid and lactate salts. It is mainly used as an acidulant and preservative. Lactic acid has a mild acid taste and does not overpower weaker aromatic flavors. Since it occurs naturally, it does not introduce a foreign element into…
