Branched-chain amino acids

It is also found in the frigid North Atlantic, and utilizes the Anti-Freezing Protein 1WFB. This scleroprotein is fibrous, and consists of 38 amino acids after removal of the initial signal peptide, as well as a secondary sacrificial section. Before cleaving, the full chain is 82 amino acids long. As the initial form is only present during the production of the protein, it will not be investigated in depth. Secondary structure in the 1WFB protein is peculiar – it…

Cell penetrating peptides are proteins or peptides that typically consist of 5-30 amino acids. These peptides are unique in that they are able to cross cell membranes and other barriers throughout the body such as the blood brain barrier, intestinal and nasal mucosa, and even skin. Using CPPs, scientists are now able to explore their potential as a means of transporting cargo into cells and across bio barriers. With their ease of preparation and generally nontoxic nature, CPPs have gained a…

incomplete of essential amino acids, and thus one must consume red meat in order to have a balanced diet. The RDA recommends we consume 0.8 grams of protein for every Kg that a person weighs. Food and Nutrition Board, Institute of Medicine. (2002) Proteins consists of amino acids, these are often referred to as its building blocks. Human beings have a biological requirement for amino acids and cannot synthesise 9 of the 20 most common. These 9 are called the essential amino acids and must be a…

1998b). They are often present in much higher concentrations in enzyme hydrolysates and have been correlated to beany off-odours described in numerous literature. Solina et al. (2005) compared the volatile components of soy protein isolate (SPI) and acid-hydrolysed soy protein and concluded that the significantly higher lipid content of SPI was responsible for green or beany odours attributed to high levels of aliphatic aldehydes and ketones. The formation of undesirable lipid-derived products…

describe two groups of proteins and give some examples. Proteins (also called polypeptides, peptides or amino acids) are large polymers and main components of cells. They are produced by condensation reaction from amino acid monomers, therefore proteins are called condensation polymers. Each protein is formed by a unique sequence of 20 naturally occurring amino acids. However, not all the amino acids need to be find in one protein. Some can be found many times and some are not used at all.…

either side of the beta sheets and are fairly close together on either site. Q4) The α helices and the β strands are connected by loops made of amino acids. Q5) There is a significant amount of space, and thus a large interface between the subunits that form dimers. The interface consists of a few loops and a few protruding amino acid side chains. Q6) The interface between subunits probably contains the binding site for activators and inhibitors. Q7) Since most of the effector…

for proteomic analysis. Only a few proteases that are useful for proteomic analysis. For instance, trypsin and chymotrypsin are often used to cleave proteins at selective amino acid residues. Trypsin cleaves on the C-terminal side of the lysine and arginine amino acids, whereas chymotrypsin cleaves after the aromatic amino acids. Trypsin exhibits higher activity and narrower specificity compared to chymotrypsin. When the lysine reside is modified or flanked by proline, cleavage of trypsin is…

If one fatty acid is bonded with the glycerol, it’s called a monoglyceride. If two are bonded, it’s a diglyceride. Three is the max amount, and they are called triglycerides. They store energy for living things. An example is steroids, which are lipids that have had…

To be specific, it helps control the “regulation of vascular tone, homeostasis of blood pressure and proliferation of vascular smooth muscle cells” (CITE). The hempseed has a rich content of linoleic acid, which reduces the cholesterol level of the body, and low cholesterol helps decrease the risk of heart attack. It also contributes in regulation and avoidance of blood pressure. (Rodriguez-Leyva and Pierce). Their arguments mainly focus on the contribution…

6 ingredients for a healthy lifestyle Is your nutrition healing or harming you? The quest for healthy living is not a sprint but a marathon. It takes a learning curve that begins with setting the tone on the right foundation. 6 building blocks make this foundation. This is a fact backed by centuries of research done in the field of medicine and nutrition. When you become familiar with the functions of these building blocks within the human body, it provides you with the framework to make…
