THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

of storage pathways‚ such as lipogenesis. Insulin stimulates lipogenesis in three main ways. Malonyl-coenzyme A In fat synthesis‚ the enzyme pyruvate dehydrogenase‚ which forms acetyl-coA‚ and also acetyl CoA carboxylase which forms malonyl-coA are obvious control points. These are activated by insulin. This leads to an overall increase in the levels of malonyl-coenzyme A‚ which is the substrate required for fat synthesis. Thus‚ the flux down storage pathway is increased when there

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

Acetylcholine is synthesized from acetyl coenzyme A and choline by the enzyme choline acetyltransferase‚ Coenzyme A is synthesized in mitochondria. Parts in the body that use or are affected by acetylcholine are referred to as cholinergic. it is the chemical that motor neurons of the nervous system release

Diet Analysis Proteins: After compiling data from my diet analysis‚ it became evident that my protein intake was within normal limits for my weight at 104% (97 grams) of the recommended range for me to lose weight. However‚ while being overweight‚ my calorie intake as a whole needs to be decreased in order to reach a healthy weight. Excess protein can lead to heart disease because a lot of it‚ at least in my diet‚ comes from saturated animal fats. These fats contribute to plaque buildup in the
