Which functional group is found in glycerol but not in a fatty acid?
Which functional group is found in glycerol but not in a fatty acid?
Glycerol is a triol, an alcohol which contains three hydroxyl functional groups. A fatty acid is a long carbon chain, generally from 12 to 24 carbons in length, with an attached carboxyl group. Each of the three fatty acid molecules undergoes an esterification with one of the hydroxyl groups of the glycerol molecule.
What is the name of the functional group that is at the end of fatty acid chains?
carboxyl group
What type of lipid does not have glycerol?
Sphingomyelin is a phospholipid found in membranes that is not derived from glycerol.
Do fats contain glycerol?
A fat molecule consists of two main components: glycerol and fatty acids. Glycerol is an alcohol with three carbons, five hydrogens, and three hydroxyl (OH) groups. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.
Are there any elements in glycerol that are not in carbohydrates?
Are there any elements in glycerol not present in carbohydrates? No, all the same.
What is the simple formula for glycerol?
Glycerol Chemical Formula
| Chemical Formula of Glycerol | C3H8O3 |
|---|---|
| Extended Glycerol Molecular Formula | CH2OH-CHOH-CH2OH |
What is a similarity between glycerol and fatty acids?
Organic Compounds
| Question | Answer |
|---|---|
| List a similarity between glycerol and fatty acids | Both are non polar |
| Do fatty acids and glycerol both contain carboxyl group? | No |
| How are triglycerides formed? | by chemically joining one glycerol molecule and three fatty acids in Dehydration Synthesis |
What chemical substance is formed when the H and OH ends are joined?
water molecule
What elements are present in the common group of an amino acid?
Each amino acid is composed of a “common group” (a central carbon with a single hydrogen, an amine group –NH2 and a carboxyl group –COOH) and a “variable group“ designated as R. It is the variable group or R group that determines the differences in properties.
What molecule remains the same in any fat?
Part A: Fats On a molecular basis, all fats are somewhat similar. Just as carbohydrates are made of monosaccharide molecules, all fats are composed of smaller molecules. The smaller molecules in fats are glycerol and fatty acids.
What purpose is served by the loss of an H and OH?
Two molecules combine usually by some sort of attraction between them. When one molecule loses OH- ion, it becomes positively charges while the other molecule loses H+ ion and becomes negatively charged.
