Biochemistry of Proteins; Isolation of Ovalbumin and Enumeration of thiol groups Abstract Thiol groups are important to protein folding and forming disulphide bonds that are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy

Protein synthesis occurs in two steps : Transcription and Translation. Transcription is the process of creating an mRNA copy of a DNA template; the mRNA is then translated into protein. The Messenger RNA (mRNA) contains the genetic information is copied from DNA during transcription . During translation‚ ribosomes synthesize the proteins using the mRNA copy produced during transcription. Proteins are complex molecules that each has a very unique shape‚ structure and function. The shape of the

mixture was then slowly heated while being stirred consistently. Once white clumps (curds) were seen the burner was turned off. 5. The filtering apparatus was set up. 6. The mixture was poured into the filtering equipment until all liquid (whey) was separated from the curds. 7. The way was then poured into the sink. 8. Curds were then put back into their original beaker and one spatula of baking soda was put into the mixture. 9. The mixture was stirred and then put on a two pieces of paper

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

I like cheese.Cheddar cheese is a relatively hard‚ pale-yellow-to-off-white (unless artificially coloured)‚ sometimes "sharp" (i.e.‚ acidic)-tasting‚ natural cheese. Originating in the English village of Cheddar in Somerset‚[1] cheeses of this style are produced beyond this region and in several countries around the world. Cheddar is the most popular type of cheese in the U.K.‚ accounting for 51 percent of the country’s £1.9 billion annual cheese market;[2] it is also the second-most-popular cheese

Describe how Bacteria decode its genetic information to produce proteins? Intro(10mins) Bacteria belongs to a group of organism that lacks cell nucleus and membrane bound organells. This group of organisms are termed as prokaryotes. Prokaryotes follows the central dogma of molecular biology first proposed by Francis Crick in 1958 to synthesize proteins from mRNA through a process called translation and the mRNA is being synthesized from the DNA by another process called Transcription.

Idea: How long will fresh milk last for after its expiry date? Aim: To determine what conditions help increase the likelihood of different types of fresh milk going off after the provided expiry date. Background Information: Full-Cream milk has on average 3.8% fat. Lite milk has less than 1.5% fat unless otherwise specified. Skim milk has less than 0.15% fat. No fat milk has less than or equal to 0.1% fat. Milk is detected as mouldy‚ spoiled and inedible when it smells bad and when swirled‚ it does

solids of milk is important when examining the quality of milk because it indicates the total amount of nutritive value of milk when water is removed (Leila et al‚ 2014). Milk is made up of about 87% of water and 13% of other components such fats‚ protein‚ carbohydrate etc. (Ward et al‚ 2016). Sheep milk is highly nutritious‚ rich in vitamins A‚ B‚ and E‚ calcium‚ phosphorus‚ potassium‚ and magnesium (Caja and Francois‚ 2017). It contains a higher proportion of short- and medium-chain fatty acids‚

Whey protein is one of the more commonly used protein supplements among bodybuilders. It is usually in powder form‚ readily mixable with water‚ juice‚ or milk to create an easy-to-consume shake. Here are some of the reasons why it is a favorite among the experts in the industry: 1. It contains majority of the essential amino acids that will help restore and bulk up your muscles. In bodybuilding‚ the person is subjecting his or her muscles to extreme stress so naturally‚ there is some form of breakdown
