Do lipids deliver amino acids?
Lipids include all fats and so it doesn't follow that they deliver amino acids. Amino acids are the building blocks of proteins.
Answer 1) Amino acids! Becuase amino acids are basically lipids, fats, and oils. Answer 2) Amino acids are the monomers of proteins. Amino acids, however, are not lipids, fats or oils. Fats and oils are made up of fatty acids and glycerol. Lipids in general include fats and oils, but also include any other lipophilic natural molecules such as steroids, terpenes, phospholipids and many other compounds.
When discussing pure carbohydrates, lipids, and protein: Amino acids contain Nitrogen and some contain sulphur which are not found in the strictest definition of carbohydrates and lipids. However carbohydrates and lipids can also combine with amino acids to form compounds like glycoproteins and ceramides.
No. Amino acids are the building blocks of proteins, which are in a different category than are lipids, which can also be classified as fats. Examples of lipids are phospholipids (in cell membranes), steroids, glycerols and fatty acids, and cholesterol. If you want to know more about the role of amino acids in Protein synthesis (because this is why they exist at all--to make protein), then I would look at this presentation: http://www.wisc-online.com/objects/index.asp?objID=AP1302
The monomers of proteins are known as amino acids. ...A further explanation: Do not confuse amino acids with nucleic acids. Nucleic acids are DNA and RNA and are another one of the BIG 4 macromolecules that are needed to survive. The 4 are: Carbohydrates (monomer: monosaccaride) Proteins (monomer: amino acids) Lipids (monomer: fatty acids) Nucleic Acids (monomer: nucleotides)
