What else can I help you with?
Where would the leucine side chain most likely be found in a protein dissolved in water?
The leucine side chain is nonpolar and hydrophobic, so it would most likely be found in the interior of the protein away from the water molecules. This helps to stabilize the protein's structure by minimizing its exposure to the aqueous environment.
A series of hydrophobic side chains will congregate together as a protein folds in an aqueous solution and be stabilized by?
hydrophobic interactions. These interactions occur between nonpolar side chains, which are repelled by water and tend to come together to minimize exposure to the aqueous environment. This clustering leads to a decrease in entropy of water molecules surrounding the protein, contributing to the overall stability of the folded protein structure.
Is trp or gln more likely on a protein surfaces?
gln is more likely to be on the surface of protein because this is hydrophilic and can make interaction with water. However, trp is hydrophobic and want to avoid any contact with water so therefore buried in the interior of protein
How are newly synthesized integral proteins inserted into a membrane?
Newly synthesized integral proteins are guided to the membrane by signal sequences that target them to the endoplasmic reticulum (ER). Once at the ER, the proteins are translocated across the membrane through a channel formed by the translocon complex. The hydrophobic regions of the protein interact with the lipid bilayer, while the hydrophilic regions remain exposed to the aqueous environment, resulting in the protein being inserted into the membrane.
Where would you expect to find a hydrophobic amino acid like valine?
Hydrophobic amino acids like valine are typically found in the core of a protein structure. These amino acids are often buried inside the protein, away from water molecules, to avoid contact with the aqueous environment. This positioning helps to stabilize the protein structure by minimizing interactions with water.

What is interior protein network?
An Interior Protein Network is when it anchors proteins to specific sites and determines the shape of the cell.
What dose integral protein do?
Integral proteins are embedded within the lipid bilayer of cell membranes and play crucial roles in various cellular functions. They assist in transporting molecules across the membrane, serve as receptors for signaling, and contribute to cell recognition and communication. Their unique structure allows them to interact with both the hydrophobic interior of the membrane and the aqueous environment outside the cell.
Why is a protein denatured?
depending upon the normal environment of the given protein, the secondary, tertiary, and the quaternary structure of the protein depend upon interactions between the amino acids of the protein itself within the structure of the protein, and interactions with the environment surrounding the proteinas an example:a protein that normally exists in an aqueous (mostly water) environment will have a structure in which the non-polar amino acids in large part will be confined to the interior of the structure where they will not interact with the aqueous exterior environment, as well as polar or charged amino acids on the exterior interacting with water, cytosolic fluid, or other polar substances.this occurs because non-polar amino acids do not interact favorably with polar solvents-just as non-polar cooking oil separates from highly polar water- and are at the lowest possible energy state when they are not interacting with polar substances. this normal interaction of proteins makes their usual conformation the most thermodynamically stable which is why they exist in solution in said conformation.Short answer: see belowif the environment is changed from polar to non-polar then the intermolecular interactions between the solvent and the amino acids of the protein will change, which would cause change of conformation of the protein structure, and thus possibly cause denaturation because as we all know from BIO 101: structure determines function.
Is ammonium sulfate aqueous?
No, by itself it is not. If dissolved in water it would then be aqueous.
Would you find hydrophillic or hydrophobic amino acids on the external surface of a protein a protein?
Hydrophilic amino acids would likely be found on the external surface of a protein as they interact with the aqueous environment surrounding the protein, while hydrophobic amino acids tend to be buried within the protein core away from water.
What is found in a membrane?
phospholipid biolayer is the membrane it self. the protein is what gets stick in the membrane. protein In context of unit membrane, it consists of a fluid mosaic of phosphoplipid bilayer and proteins. A phospholipid bilayer is made up of two layers of phospholipids with their non-polar tails facing away from the aqueous environment and polar heads towards the aqueous environment. They make up 40% of the membrane. Proteins make up 60% of the membrane and are of two types: 1. Integral proteins 2. Peripheral proteins There can also be presence of cholesterol molecules in the membrane in the hydrophobic region.

What is the salt effect?
the low concentration of salt increases the protein solubility on aqueous solution,known as salting in effect
Digestion of proteins?
Pepsin digest protein in the acidic environment of the stomach, Pancreatic Protease digests protein in the basic environment of the small intestine.
