reaction due to a catalyst. So in general biocatalysis is the use of biological (natural) catalysts, such as enzymes. These biological catalysts are used to transform organic compounds chemically. An enzyme is a protein catalyst that is responsible for the reactions in your body. Enzymes help with digestion of food, production of essential nutrients, movement of muscles, etcetera. Enzymes not only exist in our body but are used for quite a lot of other

What is cholesterol? Cholesterol is an organic molecule part of the classification of biomolecules known as lipids. It is a sterol, or steroid alcohol, that is extremely important as it is a major structural component of the cell membrane in animal cells and also a precursor for the production of steroid hormones (oestrogen and testosterone), bile salts, bile acids and vitamin D. Cholesterol is a waxy substance with the chemical formula C27H46O, it consists of three 6-memebered rings and one 5-membered

Phytochemical screening of the leaves extract All the solvent extracts were subjected to phytochemical screening and the results are presented in Table 1. Qualitative analysis of the leaf extract of A. muricata showed the presence of various phytochemicals. Methanolic extract of Annona muricata leaves showed the presence of alkaloids, flavonoids, coumarins, carbohydrates, glycosides, proteins, phenols, anthraquinones, steroids, phytosterols, cardiac glycosides and oil in the leaf. Carbohydrates,

released into the body’s system. This toxin prevents protein production and leads to cell death (Santi, Luca, Caterina Maggioli, Marianna Mastroroberto, Manuel Tufoni, Lucia Napoli, and Paolo Caraceni, 2012). RNA polymerase, the enzyme responsible for synthesizing mRNA, is the enzyme directly affected by alpha amanitin. Alpha amanitin blocks RNA polymerase from working properly within the cell (Hudon-Miller, 2013). Without RNA polymerase, mRNA is not transcribed from DNA. Without mRNA, ribosomes cannot

borrowed from the school laboratory and others were purchased from a “CVS” pharmacy. The milk was kept refrigerated prior to testing. Three beakers contained 150 mL of 100 % whole pasteurized milk. Prior to adding the store brand lactase and Lactaid enzymes, the milk was allowed to reach room temperature by setting the milk on a table for thirty minutes. Room temperature was approximately 70 degrees Fahrenheit and the air did not feel hot nor cold. The temperature was taken at the time the milk was poured

proteases, aspartate proteases and metalloproteases based on their remainder or cofactor fundamental in catalysis. A metalloproteinase, is any protease enzyme whose catalytic mechanism involves a metal. Most metalloproteases require zinc, but some use cobalt. There are two subgroups of metalloproteinases: Exopeptidases, a metalloexopeptidase is a type of enzyme that acts as a metalloproteinase exopeptidase. The term "metallocarboxypeptidase" is sometimes used to describe a metalloexopeptidas.

the activation energy. Enzymes are used to reach the correct activation energy in plants. They lower the activation energy to the correct amount for the reaction to take place. Certain enzymes catalyze certain reactions, which means that many enzymes to operate the cell. On each cell, there is a spot where the substrate will attach to the enzyme (active site). When the substrate and the enzyme come in contact with each other, it creates an enzyme-substrate complex. The enzyme and substrate then connect
