The Formation of Lipids This assignment is primarily about lipids, triglyceride, unsaturated and saturated fats I will be stating the formation of lipids and what they are made of. Lipids are a group of substances which include fats and oils, steroids which include cholesterol and some of the sex hormones, and various other substances such as the waxes which cover insect bodies and plant leaves. Lipids are a mixed group of hydrophobic compounds composed of the elements carbon, hydrogen and oxygen. Triglycerides are commonly called fats or oils. They are made of glycerol and fatty acids.
TAG is hydrolyzed in the digestive tract by the enzyme lipase , to release free fatty acids and monoglyceride. Otherwise, the key issue in the digestion and absorption of fats is one of solubility: lipids are hydrophobic, and thus they are poorly soluble in the aqueous environment of the digestive tract. The enzyme lipase is a water soluble and can only work on the surface of the fats globules. Moreover, digestion is greatly aided by emulsification, where the breaking up of fats globules into much smaller emulsion
It can be ionized in H2O since there is acidic functional groups (phenol and amide). Aspirin: has a polarity of its bonds (Carboxylic acid and ester) and polarity of it is partially same as paracetamol. It seems like its partition happens more in lipid because of the presence many non-polar hydrocarbons than polar (just carboxylic acid). It’s susceptible for ionization to water to form (carboxylate inion). Phenyl butazone Also same as Aspirin and paracetamol in its polarity, partition and susceptibility for ionization in water as it has (β-Dicarbonyl and alicyclic
Triglycerides contain three fatty acids and one molecule of glycerol. Saturated triglycerides are made up of saturated fatty acids. This means that they have high melting points and are hard at room temperature. This is because the molecules of a saturated fat are packed closely together. Examples of saturated triglycerides would be butter and fats in red meat.
The amphiphilic molecules form structures such as vesicles, liposomes, and membranes in an aqueous environment.They are insoluble in water, yet soluble in alcohol. (Human Biology) Lipids contain carbon, hydrogen and oxygen but they have far less oxygen than carbohydrates. They have high melting points. (Human Biology) The saturated acids have a higher melting point than unsaturated acids. Lipids can be extracted from plants and animals using solvents such as ether, chloroform and acetone.
Lipids Lipids are fats, oils and waxes, organic compounds containing carbon, hydrogen and oxygen. The same three elements are involved in the structure of carbohydrates, but the amount of oxygen in the molecule present is much less than in carbohydrates. Lipids are insoluble in water but soluble in organic solvents such as acetone and ether. They are relatively small molecules compared to the polysaccharides, but because they are insoluble they tend to join together to form globules. Lipids can be split into the following They are glycerol, fatty acids, oils, fats, waxes, phospholipids and triglycerides (ester).
Simple lipids include triacylglycerol’s, sterols, waxes and unesterified fatty acids. Glycerophospholipids and glycolipids represent complex lipids. Lipid function depends on the specificity. Specifically, fatty acids are the defining components of lipids and a major component of triacylglycerol’s. Fatty acids undergo β-oxidation.
The Function of Lips and Their Biological Significance Lipids are biological molecules and are insoluble in aqueous solutions but are soluble in organic solvents. Specific lipids have a physiological importance to humans; they have three major functions; serving as structural components of biological membranes, act as vitamins and hormones, provide energy storage (triaculglycerols). Lipids are made up of the elements carbon, hydrogen and oxygen. Lipids can exist as fats, oils and waxes. Fat and oils are similar in structure as they are triglycerides, however, they physically differ at room temperature fats are solid and oils liquid.
Volatile oils are insoluble in water, which is sufficient to impart taste and smell of the water and it is used for the preparation of aromatic waters in pharmacy. Volatile oils are soluble in alcohol, ether and other lipid solvents. Volatile oils are usually lighter than water. They have high refractive index and optical rotation. These oil present in entire part of the plant or other parts of plants like leaf, flower, bark, etc....
The animal fats and vegetable oils are esters of the alcohol, propane-1,2,3-triol (glycerol) CH2OHCHOHCH2OH and long chain carboxylic acids (often known as fatty acids) RCO2H, where the alkyl groups contain between 7 and 21 carbon atoms.”2 Saponification is the chemical reaction between fat and sodium hydroxide or potassium hydroxide. Saponification comes from the Latin word, “sapo,” which means soap. The fats and oils come from animal or plant sources and is made up of distinctive mixture of several triglycerides. The fatty acids of a triglyceride are weak acids composed of a carboxyl acid group with one hydrogen atom, two oxygen atoms, and one carbon atom plus a hydrocarbon chain. The hydroxide is an alkali metal such as sodium or potassium.
