Fat Fats and oils are categorized according to the number and bonding of the carbon atoms in the aliphatic chain. Fats that are saturated fats have no double bonds between the carbons in the chain. Unsaturated fats have one or more double bonded carbons in the chain.The nomenclature is based on the non-acid (non-carbonyl) end of the chain. This end is called the omega end or the n-end.ats and oils are categorized according to the number and bonding of the carbon atoms in the aliphatic chain. Fats that are saturated fats have no double bonds between the carbons in the chain. Unsaturated fats have one or more double bonded carbons in the chain.

Unsaturated fat An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain.A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. Where double bonds are formed, hydrogen atoms are eliminated.n cellular metabolism, unsaturated fat molecules contain somewhat less energy (i.e., fewer calories) than an equivalent amount of saturated fat. The greater the degree of unsaturation in a fatty acid (i.e., the more double bonds in the fatty acid) the more vulnerable it is to lipid peroxidation (rancidity).

Saturated Fats vs. Unsaturated Fats Note: It is technically more accurate to call saturated and unsaturated fats types of fatty acids, as it is specifically the fatty acid found in a fat that is either saturated or unsaturated. However, referring to fatty acids as fats is common.ats — or triglycerides — are made up of glycerol (an alcohol) and fatty acids, which are long carbon-hydrogen chains that end in a carboxyl group. Triglycerides are either saturated (with hydrogen) or unsaturated. Saturated fatty acids contain carbon atoms that connect with each other in a chain of single bonds.

- From a chemical standpoint, monounsaturated fats are simply fat molecules that have one unsaturated carbon bond in the molecule, this is also called a double bond. Oils that contain monounsaturated fats are typically liquid at room temperature but start to turn solid when chilled.

The Lipid Lowdown: Saturated, Unsaturated, and Trans Fats When all carbons in a fatty acid chain are in single bonds with hydrogen, the fat is known as saturated. This is because the carbons have the maximum number of single bonds possible, hence the term “saturated”. Unsaturated fats have at least one double bond in the fatty acid chain.

Saturated Fats vs. Unsaturated Fats Saturated fatty acids contain carbon atoms that connect with each other in a chain of single bonds. So each carbon atom can bond with two hydrogen atoms, and is said to be saturated with hydrogen. Unsaturated fatty acids contain some carbon atoms that bond with each other using double bonds.lso high in antioxidants. Cholesterol. Saturated fats increase Low Density Lipoproteins (LDL or bad cholesterol) & Very Low Density Lipoproteins (VLDL's).Sources of bad cholesterol are foods rich in trans fatty acids, refined carbohydrates, such as white sugar, and flour.

Lipids A fat molecule consists of two main components: glycerol and fatty acids. Glycerol is an alcohol with three carbons, five hydrogens, and three hydroxyl (OH) groups. Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18. In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom.

Unsaturated fat Thus, a saturated fat has no double bonds, has the maximum number of hydrogens bonded to the carbons, and therefore is saturated with hydrogen atoms. In cellular metabolism, unsaturated fat molecules contain somewhat less energy (i.e., fewer calories) than an equivalent amount of saturated fat.lthough both monounsaturated and polyunsaturated fats can replace saturated fat in the diet, trans unsaturated fats should be avoided. Replacing saturated fats with unsaturated fats helps to lower levels of total cholesterol and LDL cholesterol in the blood.

The Kinds of Fats Natural unsaturated fatty acids are in configuration that is called cis, but partial hydrogenation can flip the chemical bonds into a different configuration that is called trans. The difference between cis and trans is that the two H atoms are on the same side of the double bond (cis), compared to being on opposite sides (trans). This may not seem like much of a difference, but it affects the shapes of the molecules. In a cis configuration, the double bond creates a kink in the fatty acid. In the trans configuration, there is no kink. Therefore, a trans-fatty acid is structurally similar to a saturated fatty acid (which has no kinks, either). The kinks in the molecules determine whether the material is solid or liquid at room temperature.

Principles of Biochemistry/Lipids Thus, saturated fatty acids are saturated with hydrogen (since double bonds reduce the number of hydrogens on each carbon). Because saturated fatty acids have only single bonds, each carbon atom within the chain has 2 hydrogen atoms (except for the omega carbon at the end that has 3 hydrogens).ost naturally occurring fatty acids have a chain of an even number of carbon atoms, from 12 to 28. Fatty acids are usually derived from triglycerides or phospholipids. When they are not attached to other molecules, they are known as free fatty acids.

The Science of Fats Saturated and unsaturated fats and oils. The fatty acids in some vegetable oils are saturated: they only have single bonds between their carbon atoms. Saturated oils tend to be solid at room temperature, and are sometimes called vegetable fats instead of vegetable oils. Lard is an example of a saturated oil.

Structural Biochemistry/Organic Chemistry/Lipids Neutral fats (triglycerides) are composed of fatty acid hydrocarbon chains bonded to a single glycerol molecule. Fatty acids consist of long hydrocarbon chains with a carboxyl group while glycerol consists of 3 carbons and 3 hydroxyl groups.here is an image of a triglyceride molecule with three neutral fatty acid chains and a glycerol group. Saturated fatty acids contain single bonds between the carbons of the hydrophobic chain. Saturated fatty acids originate from animals and are found as component chains in a triglyceride molecule.

- Fatty Acids. Fatty acids consist of long, unbranched hydrocarbons with a carboxylic acid group at one end. The number of carbon atoms in a fatty acid molecule is usually even (6, 8, 12, 32, 36, etc.), although it is not impossible to find a fatty acid with an odd number of carbon atoms in its structure.

Fats, Oils, Fatty Acids, Triglycerides Common Fatty Acids. Fatty acids consist of the elements carbon (C), hydrogen (H) and oxygen (O) arranged as a carbon chain skeleton with a carboxyl group (-COOH) at one end. Saturated fatty acids (SFAs) have all the hydrogen that the carbon atoms can hold, and therefore, have no double bonds between the carbons.

Polyunsaturated fat Polyunsaturated fat. Polyunsaturated fats are lipids in which the constituent hydrocarbon chain possesses two or more carbon–carbon double bonds. Polyunsaturated fat can be found mostly in nuts, seeds, fish, algae, leafy greens, and krill. Unsaturated refers to the fact that the molecules contain less than the maximum amount of hydrogen. These materials exist as cis or trans isomers depending on the geometry of the double bond.

The truth about fats: the good, the bad, and the in-between A polyunsaturated fat has two or more double bonds in its carbon chain. There are two main types of polyunsaturated fats: omega-3 fatty acids and omega-6 fatty acids. The numbers refer to the distance between the beginning of the carbon chain and the first double bond.Both types offer health benefits.or long-term health, some fats are better than others. Good fats include monounsaturated and polyunsaturated fats. Bad ones include industrial-made trans fats. Saturated fats fall somewhere in the middle.

How Fats Work In other words, the chains are saturated with hydrogen. Fats (triglycerides) that contain palmitic acid and stearic acid are therefore known as saturated fats. Fats made up of saturated fatty acids are solid at room temperature.You can also see that oleic acid is not saturated. Two of the carbons are connected by a double bond, and two of the hydrogens are missing.ats (triglycerides) that contain palmitic acid and stearic acid are therefore known as saturated fats. Fats made up of saturated fatty acids are solid at room temperature. You can also see that oleic acid is not saturated.

Chem Ch 17 - Lipids 18.5 All fatty acids contain a long chain of carbon atoms with a carboxylic acid group.Saturated fats contain only carbon-to-carbon single bonds; unsaturated fats contain one or moredouble bonds. More saturated fats are from animal sources, while vegetable oils contain moreunsaturated fatty acids.

Saturated vs. Unsaturated Fatty Acids Fats can be saturated or unsaturated, depending on how many hydrogen atoms link to each carbon in their chemical chains. The more hydrogens attached to the chain, the more saturated the fat will be. If there are hydrogen atoms missing, the fatty acid is considered unsaturated. Saturated Fats Saturated Fats are fatty acids that have hydrogens at all the points on their chemical chain.

What are Fatty Acids? Fatty acids are acids produced when fats are broken down. They are considered “good fats.” These acids are not highly soluble in water, and they can be used for energy by most types of cells. They may be monounsaturated, polyunsaturated, or saturated. They are organic, or in other words, they contain both carbon and hydrogen molecules.

What are the types of fatty acids? Fatty acids are made up of carbon and hydrogen molecules. There are three types of fatty acids: saturated, monounsaturated, and polyunsaturated. The basic difference between each of these is the number of carbon atoms with or without two hydrogen atoms bonded to them. Here's the difference.
