Essay on Protein

Detection of Biological Molecules

Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to […]

Study: Protein supplements may do damage

Here’s some bad news for body builders seeking to buff up with protein supplements. According to a new study just released by the U. S.-based Consumer Reports, those supplements that are commonly seen in large tubs on store shelves may help build muscle, but they are not as safe as they are marketed to be. […]

Investigating Membrane Permeability

Investigating Membrane Permeability Reason for choosing beetroot as the object of experiments Beetroot is usually used as the membrane ‘disruption’ experiment. It is because of beetroot has more pigments in their vacuole. These pigments show how variables damage the membrane of beetroot. The pigments will be automatically extracted from the vacuole when the membrane is […]

Immunostaining and In Situ Hybridization

The study of gene expression provides invaluable insight into an organism’s structure and function; how it is that from a mere embryo genes can control which cells, tissues, organs and limbs will develop, providing the organism with the inherited traits that specifically adapt it to its forthcoming environment. Mutations of particular genes are sometimes associated […]

What are enzymes

Enzymes are proteins that act as catalysts. They speed up the chemical reactions which occur inside living things. Without them, all reactions would be far too slow, and living organisms would not be able to function. Enzymes are extremely efficient at doing their job. Some of the chemical reactions, which take place in our cells, […]

Does Eating a High Protein Diet Harm You

Protein is required by the body for the growth, maintenance and repair of all cells. Protein is a major component of all muscles, tissues and organs and is vital for practically every process that occurs within the body such as metabolism, digestion and the transportation of nutrients and oxygen in the blood. Having a high […]

Isolation and Purification of Proteins

The purpose of the experiment was to isolate and recognize varying protein solubilization and assaying methods by using bovine liver protein. The experiment implicated the impact of different types of solvents like ethanol, water, PBS, PBS+1% Triton x-100, and PBS+2% SDS on protein solubilization. Bradford and Ghosh/Dumbroff methods were used to calculate the amount of […]

Biology Protein Lab Report

The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver, blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed, ammonium sulfate was added to the supernatant, chilled and then spun […]
