UGC NET preparation | UGC NET preparation online | UGC NET preparation tips | UGC NET Life Sciences | CSIR JRF Preparation
1. The main reason for a protein to fold into globular shape is hydrophobic forces, which resulted due to hydrophobic effect. That is tendency of non polar compounds to aggregate in aqueous / water medium.
2. Biochemistry of protein folding
3. Basics of protein folding
4. Hydrophobic effects dives protein folding

Ab toh paper top 🤯😎😎

Why mostly, hydrophobic effects are the main driving force behind protein folding instead of h-bonds or ionic interactions? (Narendra Vikram Singh)

[@proteinengineering007]

because polar interactions dont contribute much change in enthalpy during folding..

[@amritasingh6483]

What is the role of hydrophobic interactions in protein structure and What elements influence protein folding?

[@proteinengineering007]

hydrophobic portions of protein create hydrophobic effect..

[@rachanavanjare5041]

What happens if the nonpolar protein is mixed in a nonpolar solvent? Does the protein degrade or maintain the native structure?

[@proteinengineering007]

@Rachana Vanjare .... Like dissolves Like rule is always applicable in solubility....But in case of non polar or hydrophobic proteins, these are not completely nonpolar molecules. Such proteins have only some segments which are hydrophobic....for example a membrane receptor is an example of non polar protein that contain at least 1 stretch of totally non polar amino acids....if u keep that receptor in non polar solvent it wont be soluble as it contain polar regions as well....in order to solubilize hydrophobic proteins u add detergents which can stabilize non polar regions and solubilize protein. Hypothetically, if u have a protein with all non polar residues, that wont exist in aqueous cytosol... and may be soluble only in non polar solvent. Also to keep in mind protein degradation means peptide bong hydrolysis and that can not happen just by keeping a protein in a nonpolar solvent....to break peptide bond 1 need to give heat + acid or use Proteases

[@ibt012kajalyadav7]

What is the role of hydrophobic interactions in protein structure?

[@shwetatyagi8160]

it helps in folding of protein by folding the protein in such a way that the hydrophobic part forms the core.

[@simranshree8004]

What methods used for quantifying hydrophobicity in Proteins?

[@proteinengineering007]

hydropathy index

[@amritasingh6483]

What drives the hydrophobic effect and What is the difference between van der Waals and hydrophobic interactions ?

[@proteinengineering007]

VDW forces occur between nonpolar molecules...whereas hydrophobic effects is due to water

[@simranshree8004]

How significant are hydrophobic interactions in protein-ligand complexes?

[@proteinengineering007]

very crucial...thats why most drugs have hydrophobic group so that diffuse faster to target site in aqueous medium

[@JanhaviRai-IBT-]

Do hydrophobic interaction are bonded together?

[@proteinengineering007]

sliding interactions...very weak in nature

[@ibt012kajalyadav7]

Do hydrophobic molecules attracted to each other?

[@proteinengineering007]

ofcourse yes

[@JanhaviRai-IBT-]

How hydrophobic interaction occurs in any molecule?

[@proteinengineering007]

vander walls forces u call them

[@rohantyagi9266]

What happens when a hydrophobic molecule is exposed to water?

[@proteinengineering007]

it aggregates due to hydrophobic effect..

[@apaarnasrivastava4126]

How does urea diminishes the hydrophobic effect ?

[@proteinengineering007]

non polar side chains prefer urea over water so help in denaturation @Ms Apaarna

[@nakul_963]

sir but how is hydrophobic effect responsible for protein folding

[@proteinengineering007]

Polypeptide chain adopt 3d shape after translation, in the cytosole is because it contains stretches of non polar residues. non polar stretches tend to stick together to avoid water contacts. so acquire a shape. @19IBT034 Prakhar

What if a person with strong will drinks water while having this deadly disease,, what would have happen?
