Why do serum protein molecules such as albumin and lysozyme adopt different charges within the physiological pH?
Proteins are molecules consisting of a linked chain of subunits called amino acids. Twenty different amino acids occur naturally. Different proteins (arising from different genes) will have different amino acid sequences. Each amino acid has a portion called a "side chain" that is unique in chemical composition and properties. The side chain can extend into the aqueous medium surrounding the protein. Some amino acids (glutamate, aspartate) have acidic side chains and so give up a H+ ion at physiological pH and leave the side chain with a "-" charge. Other amino acids (such as arginine and lysine) have basic side chains that tend to take up a H+ ion from the surrounding water and this confers a "+" charge on these units. Some amino acids (glycine, serine) do not interact with H+ ions at all. Thus, the net charge (sum of + and - charges) on any protein at a given pH is strictly a function of its amino acid composition. The pH that causes the net charge to be zero is called the isoelectric point and this parameter is measurable in the laboratory and can vary widely among different proteins.

What molecule is larger glucose or albumin?
Glucose molecules are larger than water molecules.
What type of protein is often used to carry other molecules?
glubour
Why doesn't albumin diffuse?
Albumin does not diffuse into interstitial compartment. That is the design of the nature to maintain the flow of fluid back from tissue to cardiovascular system. This takes place at the distal end of the cappilaries. Sometimes albumin diffuses into the tissue space in some pathological conditions and you land up in acute renal shut down.
What is an indicator for Albumin?
A common indicator for albumin is low serum albumin levels in blood tests. Low albumin levels can indicate malnutrition, liver disease, kidney disease, or other health issues that affect protein synthesis or metabolism.
What does albumin bind with in the body?
Albumin in the body binds with various substances such as hormones, fatty acids, bilirubin, and drugs. It plays a crucial role in transporting these substances throughout the body and maintaining osmotic pressure in the blood.
What information have you gained about the characteristics of lysozyme and albumin?
Lysozyme is an enzyme that helps break down bacterial cell walls, while albumin is a protein that regulates blood volume and helps transport molecules. Lysozyme is smaller in size compared to albumin and is known for its antimicrobial properties, while albumin is a major contributor to maintaining osmotic pressure in the blood. Both proteins play crucial roles in various biological processes.
Is albumin a polysaccharides?
No, albumin is not a polysaccharide. Albumin is a type of protein found in blood plasma that helps regulate osmotic pressure and transport molecules. Polysaccharides, on the other hand, are complex carbohydrates made up of multiple sugar molecules bonded together.
Does albumin change when iodine is addded?
No,Because albumin does not have any starch in it.
What molecule is larger glucose or albumin?
Glucose molecules are larger than water molecules.
What are functional proteins?
Storage molecules, transport molecules, and movement.
Is albumin a monomer?
No, albumin is not considered a type of monomer. It is considered a type of polymer made of many molecules.
What happens when you add alcohol to the egg albumin?
When alcohol is added to egg albumin, the protein structure in the albumin can denature, leading to the unfolding of the protein molecules. This can result in changes in the texture and consistency of the albumin, affecting its ability to form a stable foam or gel.
What results from boiling albumin?
Boiling albumin denatures the protein, causing it to unfold and lose its structure. This can result in the albumin becoming insoluble and forming a solid mass. Additionally, boiling can alter the functional properties of albumin, making it less effective in tasks such as emulsification or binding other molecules.
What type of protein is often used to carry other molecules?
glubour
Is albumin hydrophillic?
Yes, albumin is a water-soluble and hydrophilic protein found in blood plasma. It plays a crucial role in maintaining osmotic balance and transporting various molecules in the circulatory system.
Why egg albumin does not dissolve in water?
Egg albumin does dissolve in water, but it does not completely dissolve due to its complex protein structure. The protein molecules in egg albumin are large and have a unique shape, making it difficult for them to fully disperse in water. This is why egg albumin forms a suspension or colloid when mixed with water rather than dissolving completely.
What does AlbG means?
AlbG stands for Albumin Globulin. There are different kinds of protein in the body. Albumin blood level is an indicator of liver and kidney function.
