Branched-chain amino acids

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…

quantity taken for amino acid analysis. Diluted hydrochloric acid was used for Free amino extraction. Nitrogenous macromolecules that were co-extracted were precipitated using sulfosalicylic acid and removed by filtration. A mixture of performic acid and phenol was used for Oxidation at 0°C. Hydrolysates of the sample were then adjusted to pH 2.2 using 7.5M sodium hydroxide sol. Amino acid analyzer based on ion exchange chromatography was used to separate amino acids. Amino acids were…

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…

Vitamin D exists in two forms. These forms are Vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). Vitamin D3 production occurs in the skin when exposed to ultraviolet sunlight. Such exposure to ultraviolet light initiates conversion of 7-dehydrocholesterol to Provitamin D3, a precursor of Vitamin D3, and consequently to Vitamin D3. Moreover, it can be obtained from animal sources including fish’s liver oil and flesh of fatty fish. On the other hand, Vitamin D2 (ergocalciferol) is…

properties of amino acids, the components used to create proteins, vary as determined by their r-group; some r-groups are hydrophobic while others are hydrophilic. Engleman’s and Kyte and Doolittle’s scales quantify the degree of this hydrophobicity. Through this experiment the experimenters hoped to gain an understanding of the correlation between Engleman’s and Kyte and Doolittle’s values and solubility, or the amount of amino acid dissolved, as well as how hydrogen bonds affect solubility of…

fish. The protein provided by the fish is among the easiest protein to digest. Expert also agree that, even in small quantities, fish can have a significant positive impact in improving the quality of dietary protein by complementing the essential amino acids that are often present in low quantities in vegetable-based diets. Thus, this shows that it is important to consume fish in our daily life. But in today modern world, there are two types of fish, which are wild-caught…

from a base sequence of 20 amino acids at the ribosome in cells. There are over 100,000 different proteins encoded by thousands of different genes within the human body. They all perform different functions e.g. antibodies providing immunity and enzymes catalysing metabolic reactions. The determination of which protein is made stems from the sequence of nucleotides in the DNA molecule. These are translated into RNA containing codons that each correspond to one amino acid; there are 61/4. A…

Ribs are an important part of numerous humans’ appetite in the United States. As yummy as these juice ribs are, they aren’t the best for our bodies and health. We usually get ribs from pigs, but pigs aren’t born and raised in the cleanest places which results in diseases. This affects humans because we love to consume these animals. The production of ribs doesn’t benefit the environment either. As you can see, there are positives and negatives about eating ribs, and hopefully the negatives…

My journey starts in Rwanda, a small country in East Africa. It started after I excelled in the national examination, an exam for high school students pursuing college admission, and got rewarded a scholarship to study college in the US. The experience I gained throughout my scholarship period, research, and background inspired me to pursue graduate studies. This goal has been an important reason for both my education and life pathways. In Rwanda, my country of birth, there is a presidential…
