What is hydrophobic and how do you determine if a molecule is hydrophobic?
Hydrophobic describes molecules that are repelled by water. You can determine if a molecule is hydrophobic by looking at its structure - if it contains mostly nonpolar covalent bonds or hydrophobic functional groups (e.g. alkyl groups), it is likely to be hydrophobic. Additionally, hydrophobic molecules tend to aggregate together in water due to the hydrophobic effect.
Why cant proteins and polysaccharides diffuse through the membrane like water does?
Proteins and polysaccharides are too large to pass through the hydrophobic lipid bilayer of the cell membrane. Water, being a small molecule, can easily pass through the membrane via simple diffusion. Proteins and polysaccharides typically require specialized transport mechanisms, such as channels or carrier proteins, to facilitate their movement across the membrane.
Is the molecule nonpolar and hydrophobic or hydrophilic?
The molecule is nonpolar and hydrophobic.
Are hydrophobic substances polar or nonpolar?
Hydrophobic substances are nonpolar.
Is the 20 different polysaccharides used to make proteins true or false?
Is the 20 different polysaccharides used to make proteins true or false?
Why proteins and polysaccharides cannot diffuse through the membrance?
They are too large and usually contain hydrophilic regions which prevent movement across the hydrophobic core of the plasma membrane.
What are the intermolecular of polysaccharide?
Polysaccharides are held together by intermolecular forces such as hydrogen bonds between the individual sugar molecules. These hydrogen bonds contribute to the stability and structure of the polysaccharide molecule. Additionally, polysaccharides can also interact through van der Waals forces and hydrophobic interactions.
Is polysaccharides a portein?
No. Polysaccharides are carbohydrates.
What are the subunits polysaccharides?
The subunits of Polysaccharides are monosaccharides
What are compounds with more than two simple sugars joined together?

What are exmaples of polysaccharides?
Starch and Cellulose are both polysaccharides
Are polysaccharides carbs?
Yes, polysaccharides are complex carbohydrates.
Is cholesterol hydrophobic or hydrophobic?
Cholesterol has many hydrophobic side chains and a single hydrophilic side chain. Because it contains both hydrophilic and hydrophobic groups, it is amphipathic.yes cholesterol Hydrophobic , choestol not soluble in water
