Glycolipids play an important role in several biological functions such as recognition and cell signalling events. Glycolipids are lipids with a carbohydrate attached by a glycosidic bond or covalently bonded. They are found on the outer surface of cellular membranes where it plays a structural role to maintain membrane stability, and also facilitate cell-cell communication acting as receptors ...
The integumentary system provides a waterproof layer to keep water inside the body. The integumentary system consists of the skin, hair, nails, glands, and nerves. Of these, it is the skin that protects the body from dehydration. The skin is waterproof because its outer layer contains a protein called keratin and glycolipids. Layers of the Skin The skin consists of three layers The epidermis ...
Fats are important components of the cell membrane Both carbohydrates and Fats are modified extensively and sometimes combine to perform specialized biological functions. There are phospholipids, glycolipids, glycerophospholipids, sphingolipids, etc which yield different properties to areas of the cell membrane known as lipid rafts.
Lipids are the macromolecules that are produced by kind of condensation reaction i.e dehydration synthesis. Dehydration synthesis being sort of condensation reaction is usually involved in synthesis of macromolecules. It involves the joining of the two smaller molecules of low molecular weight i.e monomers with the removal of water(H_2O) molecule to form larger molecules having high molecular ...
Hydrogen to carbon is two to one, but oxygen is less than one. In carbohydrates the C:H:O is 1:2:1, this is why they are called carbohydrates, carbon and hydrous, which is water. one carbon ,two hydrogen and one oxygen just like water. In lipids the components are the same but the ratio is less for oxygen, so it is 1:2:less than one for C:H:O.
The diffusion takes place by simple and facilitated mode in the cell membrane. The diffusion through the membrane are of the simple and facilitated type. The simple passive diffusion occurs when small molecules pass through the cell membrane. The facilitated diffusion depends on carrier proteins that are impregnated in the cell membrane. The carrier proteins allow specific substances to cross ...
They consist of long chains of C, H, and O. In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous. Carbohydrates share the C ...
A fatty acid consists of a carboxyl head (COOH) bonded to a hydrocarbon tail. An unsaturated fatty acid contains one or more double-bonded carbons in the hydrocarbon tail, reducing the amount of hydrogen atoms present. A fatty acid consists of a hydrocarbon chain bonded to a carboxyl group (COOH). The carboxyl group is referred to as the head, and the hydrocarbon chain is referred to as the ...
Polymers are chains of smaller molecules that can interlink, while lipids have a starter molecule, like a fatty acid, and build long chains through a chemical reaction, like dehydration. Polymers are chains of subunit molecules that are all similar in a way that allows the subunits to continue building longer macromolecules on either end. By contrast, lipids are chains of carbohydrates that ...
Lipids, which include fats and oils are non-polar and hydrophobic. Non-polar substances such as fats and oils cannot be dissolved in water because they have made up of only carbon-carbon and hydrogen-carbon bonds. Only polar solutes dissolve in polar solvents,
