Lipids and Proteins? Proteins and Amino Acids?

Question

What is the relationship between lipids and proteins?
What is the relationship between proteins and amino acids?

They are all building blocks for structures in living things. However, what is there relationship between these individual pairs?

Answer 1

Proteins are amino acid polymers. So amino acids are the building blocks of proteins, though not all biologically significant amino acids are incorporated in proteins. For example L-ornithine is involved in the urea cycle and L-carnitine in lipid catabolism.

Lipids are generally not related with proteins. There are some exceptions. Some integral membrane proteins have a lipid anchor that helps them attach to the the cell membrane.
The only relation I can think of is that some lipids act as effectors for some enzymes (proteins) and that lipids are synthesized, modified and broken down by enzymes (proteins).

Answer 2

Well, ask yourself this, Are lipids soluble in a polar solution such as water, blood, etc.? The answer is no, so how do these lipids travel through your body. The same idea applies to you...how do you get to another country? You get carried there by either a plane, bus, or train. There is a mode of transportation that will allow you to get on the road and get to where it is you are going. Same with lipids, proteins such as Albumins in the blood help transport lipids throughout the body and drop them off at their destination. And Proteins are made up of Amino Acids. They are just long chains of Amino Acids folded and curled up to form a specific protein. Since there are 20 Amino Acids, there is a almost an unlimited amount of sequences and orders that there can be many distict proteins that provide different functions. Hope this helps out a bunch.

Proteins And Lipids

1.ans: a group of hydrophobic molecules such as fats‚ oils‚ and waxes (lipo = fat) 2.ans: In nutrition, the main function of lipids is the great energetic value that can be given with a small quantity of aliments. The long and total lack of fats produces serious disorders: stops the growth, skin modification, mucosa, hair and nails. Fat intemperance can provoke liver disease and favors obesity. In organism, fats circulate vitamins A, D, E and assure absorption in digestive canal. role: tissues reconstruction; nervous system organization; increases and assures a normal function of the skin; antibodies formation; good function of endocrine glands(thyroid); water metabolism; The fats accumulated and deposited in the body are a "food store" and in case of alimentary restriction, they serve at the body's nutrition. 3.ans: Glycerolipids are composed mainly of mono-, di- and tri-substituted glycerols,[5] the most well-known being the fatty acid esters of glycerol (triacylglycerols), also known as triglycerides. These comprise the bulk of storage fat in animal tissues. Additional subclasses are represented by glycosylglycerols, which are characterized by the presence of one or more sugar residues attached to glycerol via a glycosidic linkage. Examples of structures in this category are the digalactosyldiacylglycerols found in plant membranes and seminolipid from mammalian spermatazoa. Glycerophospholipids, also referred to as phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. Glycerophospholipids[6] may be subdivided into distinct classes, based on the nature of the polar headgroup at the sn-3 position of the glycerol backbone in eukaryotes and eubacteria or the sn-1 position in the case of archaebacteria. Examples of glycerophospholipids found in biological membranes are phosphatidylcholine (also known as PC or GPCho, and lecithin), phosphatidylethanolamine (PE or GPEtn) and phosphatidylserine (PS or GPSer). In addition to serving as a primary component of cellular membranes and binding sites for intra- and intercellular proteins, some glycerophospholipids in eukaryotic cells, such as phosphatidylinositols and phosphatidic acids are either precursors of, or are themselves, membrane-derived second messengers. Typically one or both of these hydroxyl groups are acylated with long-chain fatty acids, but there are also alkyl-linked and 1Z-alkenyl-linked (plasmalogen) glycerophospholipids, as well as dialkylether variants in prokaryotes. Sphingolipids are a complex family of compounds[7] that share a common structural feature, a sphingoid base backbone that is synthesized de novo from serine and a long-chain fatty acyl CoA, then converted into ceramides, phosphosphingolipids, glycosphingolipids and other species. The major sphingoid base of mammals is commonly referred to as sphingosine. Ceramides (N-acyl-sphingoid bases) are a major subclass of sphingoid base derivatives with an amide-linked fatty acid. The fatty acids are typically saturated or mono-unsaturated with chain lengths from 14 to 26 carbon atoms. The major phosphosphingolipids of mammals are sphingomyelins (ceramide phosphocholines), whereas insects contain mainly ceramide phosphoethanolamines and fungi have phytoceramidephosphoinositols and mannose containing headgroups. The Glycosphingolipids are a diverse family of molecules composed of one or more sugar residues linked via a glycosidic bond to the sphingoid base. Examples of these are the simple and complex glycosphingolipids such as cerebrosides and gangliosides 4.ans: Proteins are large organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. 5.ans: Proteins have many functions. They serve as enzymatic catalysts, are used as transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored in the liver as a complex with the protein ferritin); they are used in movement (proteins are the major component of muscles); they are needed for mechanical support (skin and bone contain collagen-a fibrous protein); they mediate cell responses (rhodopsin is a protein in the eye which is used for vision); antibody proteins are needed for immune protection; control of growth and cell differentiation uses proteins (hormones). These are just a few examples of the many, many functions of proteins.
