Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen‚ CO2 and lipid soluble molecules

How Much Protein Do You Really Need? Why is protein important? Protein is part of an important food group that you will need in order for your body to be able to function properly. As a macronutrient‚ protein allows your body to undergo proper growth and development‚ as well as to strengthen its immunity against various sicknesses and diseases. Protein is also responsible for acting as the main building block that repairs your tissues‚ organs‚ tendons‚ muscles‚ and even your bones‚ skin‚ and eyes

A catalyst is a substance that has the capacity to speed up chemical reactions without itself being altered after the reaction is complete. Characteristics of Enzymes 1. Most enzymes are proteins or proteins combined with other chemical groups‚ and other enzymes (ribozymes)

what are carbohydrates and what is the function of carbohydrates in the body? And secondly‚ what is meant by a low carb diabetic diet? The function of carbohydrates is to provide your body with it’s main source of energy. Your body will either use that energy straight away or store it for later. Carbohydrates are recognised as one of the most important influences on blood sugar levels. Many people with diabetes have found that eating a low carb diabetic diet helps them to control

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example

EXTRACTION AND ISOLATION OF PROTEINS Background of the experiment Pure proteins are not readily available for study or use. There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many possible sources where we could get proteins. It can be from plants

EXERCISE 3: DIFFERENTIAL PROTEIN PRECIPITATION Vanessa Andrea Estepa University of Mindanao‚ College of Science and Mathematics ABSTRACT: Denaturation is the disruption in the original conformation of the protein wherein the secondary‚ tertiary and quaternary structures are all affected. Denaturation is brought about by various kinds of physical and chemical means; this includes the addition of strong acids‚ heavy metal cations‚ alkaloidal reagents‚ salting out and addition of organic solvents.

High Protein Diets: Good or Bad? Lose weight while feasting on steak‚ burgers‚ cheese‚ and bacon? All without feeling hungry? What’s not to love? Meat lovers have flocked to high-protein‚ low-carb plans like Atkins‚ Zone‚ Protein Power‚ and Sugar Busters. While these diets can work‚ you need to carefully consider the risks and rewards before deciding if one is right for you. How Much Protein? Most Americans get 12%-18% of their calories from protein. With a high-protein diet‚ it can be much

Amino Acids Glycine is the smallest of the amino acids. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH‚ glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic
