biological catalysts. They are made in livings things built up by amino acids to make protein. Enzymes are able to speed up reactions and can repeat reactions. There are various factors that affect the activity of enzymes they are: "Y Temperature "Y pH "Y Specificity "Y Concentration of enzyme or substrate Enzymes are specific‚ this means that they only work on one substrate molecule. A substrate molecule is what the enzyme actually works on. The factors I have chosen to investigate are temperature

Tracing the footprints of Proteomics – To compare and study the techniques used in proteomics since the last decade. Abstract: Proteomics is a study of the proteome of an organism. The last few decades have seen a rapid progress in the development of this field. This paper attempts to compare and contrast the way in which proteomics studies are performed today as opposed to those performed ten years ago and analyse its future implications. The thrust of research while studying biology at a

Bromelain According to Alternative Medicine Review (2010)‚ bromelain is a general name for the family of sulfhydryl-containing proteolytic enzymes obtained from the pineapple plant (Ananas comosus). Aside from the primary component of bromelain which is the sulfhydryl proteolytic enzyme‚ it also contains of different elements that makes it of more beneficial. One of the components includes escharase which is a non-proteolytic substance in bromelain that is essential in the action of topical bromelain

the enzyme and thus increase thermal stability. The micro environment of surface and enzyme has a charged nature that can cause a shift in the optimum pH of the enzyme of up to 2 pH units. This may be accompanied by a general broadening of the pH region in which the enzyme can work effectively‚ allowing enzymes that normally do not have similar pH regions to work together. • Carrier-Binding: the binding of enzymes to water-insoluble carriers. • Cross-Linking: intermolecular cross-linking

used for preventing muscle soreness after intense exercise. This use has been studied‚ and the evidence suggests bromelain doesn’t work for this. Some people use a product (Phlogenzym) for arthritis (osteoarthritis) that combines bromelain with trypsin (a protein) and rutin (a substance found in buckwheat). Bromelain used in this way seems to reduce pain and improve knee function in people with arthritis. There isn’t enough scientific evidence to determine whether or not bromelain is effective

Stem Cell Culture Human embryonic stem cells are pluripotent stem cells derived from the inner cell mass of the blastocyst‚ an early-stage embryo. To culture these stem cells under controlled environments‚ one first must have a growth medium. This growth medium is made with DMEM/F12‚ which is cell culture medium‚ a 20 percent Knockout Serum Replacement‚ 100 μM β-Mercaptoethanol‚ 1 percent non-essential Amino Acid‚ and a Basic Fibroblast Growth Factor. This medium is then changed out everyday
