Why Are Steroids Hydrophobic
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts.
How Macromolecules Are Used In The Body
For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions. Four major types of macromoleculesproteins, carbohydrates, nucleic acids, and lipidsplay these important roles in the life of a cell.

When taken in doses higher than the amount your body normally produces, steroids reduce redness and swelling . This can help with inflammatory conditions such as asthma and eczema. Steroids also reduce the activity of the immune system, which is the bodys natural defence against illness and infection.
The Biological Building Blocks
The cell is the basic unit of life. All organisms are composed of one or more cells. As will be discussed later, humans are made up of many millions of cells. In order to understand what goes wrong in cancer, it is important to understand how normal cells work. The first step is to discuss the structure and basic functions of cells.
First we will introduce the common building blocks of cells. All cells, regardless of their function or location in the body, share common features and processes. Amazingly, cells are comprised almost entirely of just four basic types of molecules. Shown above is a cell surrounded by examples of these building block molecules.
Since they are present in living things these building blocks are called biomolecules. The next sections describe the structures and functions of each of these basic building blocks. Further information on the topics on this page;can also be found in most introductory Biology textbooks, we recommend Campbell Biology, 11th edition.1

Why Are Steroids Grouped With Other Lipids
Unlike phospholipids and fats, steroids have a fused ring structure. Although they do not resemble the other lipids, they are grouped with them because they are also hydrophobic and insoluble in water. All steroids have four linked carbon rings, and many of them, like cholesterol, have a short tail.

The Big Fat World Of Lipids
ByEmily Carlson09 August 2012
When you have your cholesterol checked, the doctor typically provides your levels of three fats found in the blood: LDL, HDL and triglycerides. But did you know your body contains thousands of other types of fats, or lipids?
In human plasma alone, researchers have identified some 600 different types relevant to our health. Many lipids are also associated with diseases diabetes, stroke, cancer, arthritis, Alzheimer’s disease, to name a few. Learning more about them could point to new ways to diagnose and treat lipid-related conditions. ;
Just as genomics and proteomics spurred advances in the study of genes and proteins, lipidomics has offered a more quantitative and systematic approach to lipids research. Much of the effort has been led by a research consortium called LIPID MAPS. With funding from the National Institutes of Health, LIPID MAPS first major activity was classifying lipids into eight main categories. Six include fats from mammals and the other two include fats from bacteria, plants and marine life. Cholesterol belongs to the “sterol” group, and triglycerides are “glycerolipids.” Another category,”phospholipids,” includes the hundreds of lipids that constitute the cell membrane and allow cells to send and receive signals.
Using the lipidomics data and tools, members of LIPID MAPS have answered this last question. ;;

How Macromolecules Come Together: Hydrolysis & Condensation Reactions
Biopolymers can be built from constituent monomers or broken down into constituent monomers through the process of anabolism or catabolism, respectively. Condensation reactions are the chemical process by which two molecules are joined with the loss of water, and is the process by which carbohydrates, proteins, nucleic acids, and proteins are synthesized from simpler subunits. Because water is lost, this process can also be called dehydration synthesis.
A-H;+;B-OH;;; ; A-B; +;H2O
Hydrolysis reactions are those in which theaddition of water allows for essentially to the opposite process of condensation to occur, thereby cleaving a larger molecule into smaller substituent molecules.

Phospholipids And Biological Membranes
Triglycerides are classified as simple lipids because they are formed from just two types of compounds:;glycerol;and;fatty acids. In contrast, complex lipids contain at least one additional component, for example, a phosphate group or a carbohydrate moiety .;Figure;depicts a typical phospholipid composed of two fatty acids linked to glycerol . The two fatty acid carbon chains may be both saturated, both unsaturated, or one of each. Instead of another fatty acid molecule , the third binding position on the glycerol molecule is occupied by a modified phosphate group.
This illustration shows a phospholipid with two different fatty acids, one saturated and one unsaturated, bonded to the glycerol molecule. The unsaturated fatty acid has a slight kink in its structure due to the double bond.
Phospholipids tend to arrange themselves in aqueous solution forming liposomes, micelles, or lipid bilayer sheets.

Fatty Acids And Triacylglycerides
The;fatty acids are lipids that contain long-chain hydrocarbons terminated with a carboxylic acid functional group. Because the long;hydrocarbon chain, fatty acids are;hydrophobic; or;nonpolar. Fatty acids with hydrocarbon chains that contain only single bonds are called;saturated fatty acids because they have the greatest number of hydrogen atoms possible and are, therefore, saturated with hydrogen. Fatty acids with hydrocarbon chains containing at least one double bond are called;unsaturated fatty acids because they have fewer hydrogen atoms. Saturated fatty acids have a straight, flexible carbon backbone, whereas unsaturated fatty acids have kinks in their;carbon skeleton;because each double bond causes a rigid bend of the carbon skeleton. These differences in saturated versus unsaturated fatty acid structure result in different properties for the corresponding lipids in which the fatty acids are incorporated. For example, lipids containing saturated fatty acids are solids at room temperature, whereas lipids containing unsaturated fatty acids are liquids.
A;triacylglycerol, or;triglyceride, is formed when three fatty acids are chemically linked to a glycerol molecule . Triglycerides are the primary components of;adipose tissue;, and are major constituents of;sebum;. They play an important metabolic role, serving as efficient energy-storage molecules that can provide more than double the caloric content of both;carbohydrates;and;proteins.

Anomeric Forms Of Glucose
Fischers brilliant elucidation of the configuration of glucose did not remove all uncertainty concerning its structure. Two different crystalline forms of glucose were reported in 1895. Each of these gave all the characteristic reactions of glucose, and when dissolved in water equilibrated to the same mixture. This equilibration takes place over a period of many minutes, and the change in optical activity that occurs is called;mutarotation. These facts are summarized in the diagram below.
When glucose was converted to its pentamethyl ether , two different isomers were isolated, and neither exhibited the expected aldehyde reactions. Acid-catalyzed hydrolysis of the pentamethyl ether derivatives, however, gave a tetramethyl derivative that was oxidized by Tollens reagent and reduced by sodium borohydride, as expected for an aldehyde. These reactions will be displayed above by;clicking on the diagram.
Second, a pentamethyl ether derivative of the pyranose structure converts the hemiacetal function to an acetal.;Acetals are stable to base, so this product should not react with Tollens reagent or be reduced by sodium borohydride. Acid hydrolysis of acetals regenerates the carbonyl and alcohol components, and in the case of the glucose derivative this will be a tetramethyl ether of the pyranose hemiacetal. This compound will, of course, undergo typical aldehyde reactions.;By clicking on the diagram a second time;this relationship will be displayed above.

Cyclic Forms Of Monosaccharides
As noted above, the preferred structural form of many monosaccharides may be that of a cyclic hemiacetal. Five and six-membered rings are favored over other ring sizes because of their low;angle and eclipsing strain. Cyclic structures of this kind are termed;furanose; or;pyranose;, reflecting the ring size relationship to the common heterocyclic compounds furan and pyran shown on the right. Ribose, an important aldopentose, commonly adopts a furanose structure, as shown in the following illustration. By convention for the D-family, the five-membered furanose ring is drawn in an edgewise projection with the ring oxygen positioned away from the viewer. The anomeric carbon atom is placed on the right.;The upper bond to this carbon is defined as beta, the lower bond then is alpha.Click on the following diagram to see a;model of -D-ribofuranose.

What Are The Four Macromolecules Of Life
Biology or informally, life itself is characterized by elegant macromolecules that have evolved over hundreds of millions of years to serve a range of critical functions. These are often categorized into four basic types: carbohydrates , lipids, proteins and nucleic acids. If you have any background in nutrition, you will recognize the first three of these as the three standard macronutrients listed on nutritional information labels. The fourth pertains to two closely related molecules that serve as the basis for the storage and translation of genetic information in all living things.
Each of these four macromolecules of life, or biomolecules, performs a variety of duties; as you might expect, their different roles are exquisitely related to their various physical components and arrangements.
