Fatty acids are known as isomers. Glycerol are also isomers.
Triglycerides. Triglycerides are composed of a glycerol molecule bonded to three fatty acids.
In case of the fat molecule, you have three long chain fatty acids attached to glycerol molecule. With the help of bile salts the fat is emulsified into very fine particles. So you have very large surface area is available for lipase to act upon the fat particles. Lipase splits the bond between the glycerol and fatty acids.
No, lipid is a type of macromolecule. Lipid is a large and diverse group that includes the molecule glycerol. Glycerol is an organic compound that is part of triglyceride, which is part of lipid.
Protein
All fats of animal origin (butter, lard, cheeses, etc.).
No. Salts are not macromolecules since they cannot be broken down into molecules that exist by themselves.Macromolecules include carbohydrates, lipids, and proteins. They are respectively chains of saccharides, glycerol+fatty acids, and amino acids.Salt is not a macromolecule but has a large lattice.
triglyceride
a large fat molecule is made up of 2 things. these are called glycerol and fatty acids
Fat molecules are made up of glycerol linked to fatty acids.
Fat molecules are made up of a molecule of glycerol and three molecules of fatty acids. The fatty acids each consist of a hydrocarbon chain with a carboxyl group at one end, while the glycerol molecule has three hydroxyl groups that interact with each carboxyl.
The elements in a fat molecule is three fatty acid molecules wrapped around glycerol. The hydrocarbon chain is hydrophobic and will not dissolve in water.
The building blocks of lipids are glycerol and fatty acids. However, triglycerol is only one type of lipid. Lipid is a large and broad class that also includes steroids, glycerophospholipid, and more.
Lipids are unlike the other macromolecules in that they do not have monomers per se. They are made up of glycerol and fatty acids, but it's not like DNA which is made up of nucleotides or proteins that are made up of amino acids. However, they are still considered macromolecules as lipids are a large category of important molecules in the human body.
Fats are hydrolised to fatty acids and glycerol by fat digestion which is aided by enzymes called lipases. Since fat molecules are large in size, a larger surface area needs to be provided; this occurs during emulsification in which bile, produced by the liver, is secreted, by the gall bladder, onto fat globules in the duodenum to emulsify fats into small droplets on which lipase can function in order to break-down the fats and produce glycerol and fatty acids. Hydrogen carbonate is secreted, as well, in order to neutralize the hydrochloric acid from the stomach; an almost-neutral pH (7.5) is optimal for the activity of lipases.
Fatty acids are one of the components of triglycerides. A triglyceride is made up of three long fatty acids chains, each of them attached to the same glycerol molecule - the part that holds the triglyceride together.
a fat is a large lipid made from 2 kinds of smaller molecules: glycerol and fatty acids
In case of the fat molecule, you have three long chain fatty acids attached to glycerol molecule. With the help of bile salts the fat is emulsified into very fine particles. So you have very large surface area is available for lipase to act upon the fat particles. Lipase splits the bond between the glycerol and fatty acids.
Enzymes are catalysts. They speed up the digestion of large molecules such as proteins. Digestion is the reaction of these large molecules with water, and it results in their conversion to small, soluble molecules which can be absorbed through the intestine walls. Proteins are converted to amino acids, starch to glucose, and fats to fatty acids and glycerol. Each type of food molecule needs a different enzyme.
