Lipids are made up of carbon‚ hydrogen and oxygen (phospholipids also contain phosphate) and are found in a wide variety of organisms from bacteria to eukaryotes where they perform a wide variety of useful functions. This essay will expand on these functions to describe the role of lipids. There are several types of lipid including triglycerides‚ steroids‚ waxes and phospholipids. Triglycerides are made up of three fatty acids combined with glycerol by an ester linkage meaning they are predominantly

The Role of Lipids in the Body Donna Pote Western Governors University The Role of Lipids in the Body We have all been told at one time or another to be careful to limit the amount of fat in our diets. The thing is‚ fats play an important role in our body. They store and provide energy‚ insulate and protect our organs‚ and act as messengers‚ helping protein do their jobs. They start chemical reactions that help our immune system‚ reproduction and other aspects of basic metabolism. (Dutchen‚ 2010)

Lipids Biochemistry November 13‚ 2013 Lipids Lipids are families of biomolecules including fats and oils‚ waxes‚ steroids ‚ cholesterol and fat soluble vitamins. All lipids are naturally occurring compounds varying greatly in structure but share the common feature of being soluble in non polar solvents such as chloroform and ether but not in water. Lipids consist mainly of carbon and hydrogen atoms linked by non polar covalent

Another word for "fats." Lipids can be more formally defined as substances such as a fat‚ oil or wax that dissolves in alcohol but not in water. Lipids contain carbon‚ hydrogen and oxygen but have far less oxygen proportionally than carbohydrates. They are found in places as diverse as egg yolks and the human nervous system and are important component of plant‚ animal and microbial membranes A fatty or waxy are organic compound that is readily soluble in nonpolar solvent (e.g. ether)

Lipids‚ which are also known as fats play a very important part in our bodies‚ it provides energy to producing hormones. As humans we wouldn’t be able to digest and absorb food without lipids. Eating more fat than we need can lead to weight gain but with proper amounts of lipids they are a healthy part of our diet. The main role of lipids in our body is to provide energy for muscles and body processes. Half of the fuel our body needs when at rest or with everyday activity comes from lipids. Lipids

Fats‚ waxes‚ monoglycerides‚ and triglycerides are all types of lipids. Triglycerides are a main form of energy for both plants and animals. Triglycerides are broken down into 3 fatty acid chains. Each fatty acid chain is further broken down into multiple groups of Acetyl CoA. Acetyl CoA molecules go through the citric acid cycle and the electron transport chain. 12 ATP are formed from each Acetyl CoA molecule. Carbon chains that are saturated with hydrogen atoms Chains are straight and

Function of the Skin The skin is more than just external covering. It acts as a sensitive boundary between our bodies and the environment. The skin has several important functions‚ for example: Protection‚ temperature regulations‚ waste removal and sense of touch. Protection • The skin acts as a protective organ. The film of sebum and sweat on the surface of the skin (acid mantle). It acts as an anti-bacterial agent to help prevent the multiplication of micro-organisms on the skin. • The fat
