for the mostpart hydrophobic. peanut butter is very fatty (i.e. oily). These lipids are long chained carbon compounds, with little polarity (acid group)
Carbohydrates are hydrophilic, meaning they have an affinity for water. To test this, you can perform a simple solubility test: add the carbohydrate sample to water and observe if it dissolves. If it dissolves, it is hydrophilic; if it does not dissolve or forms a separate layer, it is likely hydrophobic.
The terminal hydroxyl group of a steroid is hydrophilic.
The polar end of a phospholipid in the plasma membrane is hydrophilic, meaning it is attracted to water. This hydrophilic end faces outward towards the aqueous environment both inside and outside the cell.
No they are opposite. Hydrophilic means water loving. Oleophilic means oil loving.

Materials that are hydrophobic (dislikes water) versus hydrophilic (likes water). The cocoa mass in chocolate is hydrophilic, whereas the hydrophobic cocoa butter fat molecules are composed mainly of carbon and hydrogen and do not readily interact with water. Hydrophobic and hydrophilic materials do not mix well. So an amphiphilic molecule (that likes both water and oil) is added. Such a mixture is called an emulsion. An "emulsifier" that is commonly added to chocolate is soy lecithin ,that promotes mixing of cocoa solids and cocoa butter: these amphiphilic molecules coat the hydrophilic cocoa solids with a hydrophobic layer, thereby helping to maintain a stable chocolate, and making the chocolate feel smooth in your mouth.

Carbohydrates are hydrophilic, meaning they have an affinity for water. To test this, you can perform a simple solubility test: add the carbohydrate sample to water and observe if it dissolves. If it dissolves, it is hydrophilic; if it does not dissolve or forms a separate layer, it is likely hydrophobic.

Yes, the heads of phospholipids are hydrophilic.
Silica is hydrophilic, meaning it has an affinity for water and tends to absorb or attract water molecules.
1. Is clean wool hydrophobic or hydrophilic? Why?
Glucose is hydrophilic, meaning it is attracted to water.
The polar end of a phospholipid in the plasma membrane is hydrophilic, meaning it is attracted to water. This hydrophilic end faces outward towards the aqueous environment both inside and outside the cell.
Starches can be both hydrophobic and hydrophilic, although most of them are hydrophilic.
