What else can I help you with?
Is triglyceride hydrophobic?
yes
Is triglycerides hydrophilic or hydrophobic?
These molecules are highly hydrophobic because the long chains of fatty acids esterified to a glycerol molecule. They are the most important lipids in plasma membrane that form the so-called lipid bilayer. When the fatty acids present in triacylglycerols are saturated, they become a strong water repelent to the cell. When these fatty acids have one or more unsaturated bonds, they turn to be more akin or water tolerant. While the unsaturated bonds are more present in fatty acids, the more water tolerant they will be.
Are triglycerides polar or non-polar?
Yes. Like carbohydrates, lipids also contain oxygen, hydrogen and carbon. But unlike COH, they have much fewer oxygen atoms. As a result lipids are said to be saturated with hydrogen atoms making the bonds between atoms non polar convalent. This means that lipids do not disolve in water. This property is know as being hydrophobic
Why are triglycerides called a neutral fat?
Triglycerides are called neutral fats because they are composed of three fatty acids and glycerol. They are neutral because their fatty acids do not have any charged groups, making them hydrophobic and nonpolar. This nonpolar nature allows triglycerides to be stored as energy reserves in the body without interfering with cellular functions.
What Bonds are between lipids?
Lipids are held together by non-covalent bonds such as hydrogen bonds and hydrophobic interactions. Furthermore, lipids can also form covalent bonds to create structures like ester linkages in triglycerides or phosphodiester linkages in phospholipids.
Is triglyceride hydrophobic?
yes
Why are lipase that are found in saliva and in the stomach not very effective at digestion?
because triglycerides are hydrophobic
Are triglycerides amphiphilic?
No. Because the polar hydroxyls of glycerol and the polar carboxylates of the fatty acids are bound in ester linkages, triglycerides are nonpolar, hydrophobic molecules, that are essentially insoluble in water.
Why triglycerides that are very hydrophobic are soluble in acetone which is a polar solvent?
Acetone is only a weak polar solvent.
Explain the difference between the solubility behaviors of glycerol and triglycerides?
Glycerol is highly soluble in water due to its hydrophilic nature, while triglycerides are insoluble in water due to their hydrophobic fatty acid tails. Triglycerides are more soluble in non-polar solvents like oils and fats.
Is triglycerides hydrophilic or hydrophobic?
These molecules are highly hydrophobic because the long chains of fatty acids esterified to a glycerol molecule. They are the most important lipids in plasma membrane that form the so-called lipid bilayer. When the fatty acids present in triacylglycerols are saturated, they become a strong water repelent to the cell. When these fatty acids have one or more unsaturated bonds, they turn to be more akin or water tolerant. While the unsaturated bonds are more present in fatty acids, the more water tolerant they will be.
Which of the lipid types are most soluble in water?
Phospholipids and glycolipids are more soluble in water compared to triglycerides due to the presence of a hydrophilic head group, which interacts favorably with water molecules. Triglycerides, being composed mostly of hydrophobic fatty acid chains, are less soluble in water.
How does phospholipid differ from triglyceride?
Phospholipids are a class of lipids, and a major component of all biological membranes, along with glycolipids, cholesterol and proteins. Phospholipids consist of a glycerol molecule chemically bonded to 2 long fatty acid chains and a phosphoester through a process called condensation. Phospholipids are amphipatic (has a hydrophillic region and a hydrophobic region) due to the hydrophillic phosphoester and the hydrophobic fatty acid chains. Triglycerides are the chemical form in which most fat exists in food as well as in the body. They're also present in blood plasma. These consist of a glycerol molecule chemically bonded to 3 long fatty acid chains via a process called condensation. Triglycerides are hydrophobic as the long fatty acid chains are hydrophobic as they are far too long to react with water.
Are triglycerides polar or non-polar?
Yes. Like carbohydrates, lipids also contain oxygen, hydrogen and carbon. But unlike COH, they have much fewer oxygen atoms. As a result lipids are said to be saturated with hydrogen atoms making the bonds between atoms non polar convalent. This means that lipids do not disolve in water.

What is the core of lipoproteins made of?
The core is made of cholesterol and triacygylcerols. It is hydrophobic.
Why are triglycerides called a neutral fat?
Triglycerides are called neutral fats because they are composed of three fatty acids and glycerol. They are neutral because their fatty acids do not have any charged groups, making them hydrophobic and nonpolar. This nonpolar nature allows triglycerides to be stored as energy reserves in the body without interfering with cellular functions.
What type of macro-molecule is also referred to as a fat?
A macromolecule referred to as a fat is typically a lipid, specifically triglycerides. Lipids are hydrophobic molecules that include fats, oils, and waxes, and they play essential roles in energy storage, insulation, and cellular structure. Triglycerides consist of glycerol and three fatty acid chains. They are a major form of energy storage in animals and plants.
