Which of these statements is true about lipids?

Top Answer

The statement that is true regarding the lipid molecules is that they have a glycerol backbone to which three fatty acid molecules are attached via ester linkage or through the amide linkage.

Which of the following is true about lipids quizlet?

Which of the following is true about lipids? Lipids found in the cell membrane are composed of one glycerol and three fatty acid chains and are called phospholipids. Triglycerides are composed of three fatty acids and one glycerol and are stable because they do not dissolve in water.

What do all lipids have in common group of answer choices?

The characteristic that all lipids have in common is that they are nonpolar molecules, which means they do not dissolve in water.

What are the 4 types of lipids and what makes the different from each other?

Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.

Which statement about unsaturated fats is true?

The correct statement concerning unsaturated fatty acids is b) They have double bonds in the carbon chains of the fatty acids. Explanation: Unsaturated fat is a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond(s) and are not completely saturated with hydrogen atoms.Sep 26, 2020

Which of the following is true about fatty acid?

Fatty acids are carboxylic acids with long-chain hydrocarbon side groups. In nature, they rarely exist as free fatty acids, rather they exist as an esterified form in a larger lipid macromolecule.

What do all lipids have in common quizlet?

What do all lipids have in common? All lipids are nonpolar and hydrophobic, thus all lipids are insoluble in water and are linked by nonpolar covalent bonds.

What do all lipid molecules have in common?

What two molecules are lipids made from? Three carbon molecule with one hydroxyl group attached to each carbon. All other bonds filled by hydrogen. What is a hydrocarbon chain?

Which of the following is a characteristic that all lipids share quizlet?

Which of the following is a characteristic that all lipids share? They are largely insoluble in water.

What are the 4 different types of lipids?

The four main groups of lipids include:

Fatty acids (saturated and unsaturated)
Glycerides (glycerol-containing lipids)
Nonglyceride lipids (sphingolipids, steroids, waxes)
Complex lipids (lipoproteins, glycolipids)

What are the 4 types of lipids and their functions?

Functions of Lipids

Storage of energy for long-term use (e.g. triglycerides)
Hormonal roles (e.g. steroids such as oestrogen and testosterone)
Insulation – both thermal (triglycerides) and electrical (sphingolipids)
Protection of internal organs (e.g. triglycerides and waxes)

What are the 4 main groups of lipids?

Major types include fats and oils, waxes, phospholipids, and steroids.

What is the structure of a phospholipid?

A phospholipid molecule has a polar "head" and a nonpolar "tail.". Much of the structure of the plasma membrane consists of a double layer of these molecules.

Which fatty acid has more than one double bond?

Fatty acids with more than one double bond are called. polyunsaturated. Linoleic acid is an example of a polyunsaturated fatty acid that has two double bonds between carbon atoms. Arachidonic acid is a polyunsaturated fatty acid with 20 carbons and 4 double bonds, so its structure is summarized as. 20:4.

How many carbons are in arachidonic acid?

Arachidonic acid is a polyunsaturated fatty acid with 20 carbons and 4 double bonds, so its structure is summarized as. 20:4. Fats are formed from. fatty acids and glycerol with the loss of the three water molecules (one for each ester bond formed). Revert fats to fatty acids and glycerol reaction.

What is the LDL?

LDL is a low-density lipoprotein involved in transporting cholesterol from the. liver to the tissues. It is spherical in shape, with an inner core of nonpolar lipids and a polar surface made up of the head of phospholipid molecules. LDL. Cholesterol is mainly synthesized in the liver.

What is the R′ group?

R′ group is the rest of the. glycerol (a three-carbon chain). Triacylglycerides, or fats, are formed by combining. three fatty acids with glycerol (a triol) to form three ester bonds. Each ester bond formed from a carboxylic acid and an alcohol leads to the loss of. one water molecule, for a total of three.
