Is Whey Protein the way to go?IntroductionWhey protein has become one of the most popular and safe ways in achieving "optimal health". Whey protein is also used to gain an "edge" is sport related activities along with bodybuilding. But where exactly does whey protein come from? Whey protein is a co-product of cheese, which is naturally in cow's milk. (Vardhanabhuti 1999) However, whey protein is not the only protein available from cow's milk. Casein is the other protein obtained threw cow's milk. Casein accounts for eighty percent of the protein found in cow's milk while whey only accounts for twenty percent. However whey protein is the most beneficial protein out of the two. Actually whey proteins are the best source of protein known to man. The other types of protein such as wheat, egg, casein, bovine colostrums, and ovalbumin do not have the excellent metabolic efficiency that whey has naturally.(Pasin 2000) However, other proteins such soy and egg are a good alternative to whey for people who are dieting or allergic to milk products. Whey protein is also popular to people who are only vegetarians or vegans.History of whey proteinNot long ago, whey protein was seen as a worthless co-product from cheese which was thrown away. This happened until the early 1990's when bodybuilders realized the nutritional benefits of whey protein. (Neville 2001) Once this happened the "protein bar revolution began to provide a portable and convenient delivery system for specific nutrients such as whey protein." (Neville 2001) Ultra Whey 99 is the protein most widely used because it "provides good-quality protein in a concentrated form with little associated fat or lactose." (Neville 2001) Protein bars are also easy to buy and consume when time is at a minimum.IngredientsProtein is an important nutrient used by everyone on a daily basis which, is made up of various kinds of amino acids. Some of these amino acids found in whey protein include: alanine, argentine, cystine, glutamate, glycine, histidine, isoleueine, leucine, lysine, methionine, phenylalalanine, praline, serine, threonine, tyrosine, and valine. Whey protein also contains "various proteins, peptides, amino acids, lactose, minerals, vitamins and varying quantities of lipids." (Walzem 357)All of the amino acids are naturally occurring and found in the Pro Performance 100 percent whey protein powder which is a highly used whey protein shake sold at nutritional stores across the world. Along with these amino acids, whey protein "supplies a high nutritional value including glutamine 'which' serves as fuel for the immune system, provides an anti-catabolic effect and is involved in protein synthesis." (www.gnc.com) Glutamine is important because it is lost during pro-longed high intensity activities. Whey protein also contains branched-chain amino acids which help the body in a few different ways. First, branched-chain amino acids "provide safe nutritional support for athletes and individuals seeking optimal...

Determination of Molecular Weight of a Protein by Gel Filtration

3339 words - 13 pages Introduction Purification of proteins is an essential technique that provides biochemists with the ability to obtain a sample that contains a specific protein of interest. In order to purify a protein biochemists typically obtain the specific extract, precipitate the protein using ammonium sulfate, preform gel filtration, and lastly run ionic and affinity chromatography. Understanding the use and methods of the different chromatography

Thus, the absorbance is directly proportional to the concentration of proteins. Eqn. 2 was used to determine the concentration of the unknown protein solution in trials 1 and 2 using the absorbance at 0.288 and 0.514

Neurons and The MECP2 Protein

1307 words - 6 pages The MECP2 protein is primarily necessary for the growth of neurons. However, the loss-of-function mutation to the MECP2 gene causes a decrease in neuron size and dendritic arborization (3). Individuals with the dysfunctional protein typically start out with normal development until about 18 months of life, and then undergo a short period of time where development ceases to occur, followed by rapid deterioration in language and motor skills

In humans, one of its functions is that it serves as a decarboxylation of substrate 1, which is pyruvate (Frank, 2005). Inhibition of PDK4 leads to higher amounts of glucose oxidation, which helps to make more pyruvate into acetyl-CoA (Zhang, 2014). This decarboxylation of substrate 1
