The Hair Follicle Stem Cell Niche and the Function of the Rac1 protein within the niche. Abstract: An adult stem cell’s niche is responsible for the preservation of the stem cell’s undifferentiated state through either intrinsic or extrinsic expression of specific proteins (Scadden‚ 2006). Situated in the bulge of the hair follicle‚ hair follicle stem cells (HFSC) are quiescent in nature and are responsible for not only its self renewal but also in the production of rapidly proliferating cells

Do Fats Digest More Slowly Than Carbohydrates and Proteins? The foods we eat are classified into six elementary groups: carbohydrates‚ fats‚ proteins‚ vitamins‚ minerals‚ and water. These foods are broken down into various nutrients during digestion. The time taken for the body to extract nutrients and the complexity of the digestion process depend on the molecular nature of the food eaten. Fat molecules seem more complex than the others so its digestion often takes a longer time. Types of Fat Fats

Proteins are made up of long chains of amino acids‚ just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiary structure is formed by even more folding and joining of the chains to make a globular mass or fibrous mass. An example of this would be a carrier protein. Proteins are needed for many things they are needed in our diet for growth and repair of cells

various methods that can be implemented that target specific proteins and/or receptors specific to particular organelles. SDS-PAGE (sodium dedocyl sulfate- polyachrylamide gel electrophoresis) is a technique used to separate proteins based on their mass. As different proteins vary in properties other than mass‚ the detergent sodium dedocyl sulfate is applied to protein samples (Pokorny‚ 2012). This disrupts associations by causing the proteins to denature and unfold into a polypeptide rod. It also prevents

such as respiration and energy production. Mitochondria even play an important role in apoptosis‚ or programmed cell death. This is achieved by disruption of electron transport‚ oxidative phosphorylation‚ and ATP production or even the release of proteins that trigger activation of caspase family proteases and alteration of cellular reduction-oxidation (redox) potential (Reed and Green‚ 1998). Succinate dehydrogenase (SDH) and malate dehydrogenase (MDH) are enzymes that play a role in the Citric Acid
