-Prion:the improper folding of a protein in the brain named PrPc. 2 important properties: -It is an infectious protein (PrPSc) that destroys nerve cells in the amyloid plaques of the brain and can lead to loss of brain function or dementia. -Has the ability to make more copies of the same misfolded protein over and over again. (Ahern & Rajagopal‚2012) Bovine Spongiform Encephalopathy: Chaperone Protein -misfolding of PrPc -> PrPSc = BSE -PrPSc passes on misfolding of prion and spreads to

applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent chapters on metabolism‚ molecular biology‚ and molecular medicine. Multiple-Choice Questions 1) Humans and mice differ because A) their cells have different small organic molecules

All orgs use same types of molecules: carbs‚ lipids‚ proteins‚ and nucleic acids 5. Instructions for growth‚ development‚ and reproduction are encoded in each organisms nucleic acids Have to know how cells are regulated and where this info is coming from Why/how energy is made or used up – always tracking

cells share; however‚ there are also important differences among various cell types (for example‚ animal cells vs. bacterial cells) • [Figure 3-23] The inside of a cell is loaded (crowded‚ packed) with molecules including RNA‚ ribosomes and proteins. o A cell is already packed‚ even with these few components; without even considering other organelles and components present in cells‚ the cell is already crowded; crowding changes the behavior of cellular components • Many different

really been a problem throughout the years. There was one case in 2012 but the meat was properly disposed of by the United States Department of Agriculture (USDA). Testing for the disease can be difficult because there are only small traces of prion protein in the blood or urine so the only reliable test comes from a necropsy. However‚ with newer technology‚ detecting the disease has come a little be easier because technology has become more developed and sensitive when it comes to detecting the disease

Proteins are arguably the most important things that people know the least about. As OpenStax CNX puts it‚ “Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins.

Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed
