The Good – Unsaturated Fats Good fats come from vegetables, nuts, seeds and fish. The two broad categories of beneficial fats include monounsaturated and polyunsaturated fats. The good healthy fats are liquid at room temperature, and do not solidify. They are different from saturated fats as that have fewer hydrogen atoms bonded to their carbon chains. 1. Monounsaturated fats have a single carbon-to-carbon double bond resulting in two fewer hydrogen atoms than a saturated fat and are responsible
Structure of fatty acids: Differentiating between fatty acids can be in two main ways: the length of free fatty acid chains and the fatty acids degree of saturation. The number of carbon atoms determine the length of fatty acid chains which often categorized as short chain fatty acids (SCFA), Medium-chain fatty acids (MCFA), Long-chain fatty acids (LCFA), and Very long chain fatty acids (VLCFA) with aliphatic tails longer than 22 carbons, while the number of double bonds between carbon atoms
Donuts, bagels, and sweet, caffeinated drinks are loaded with sodium, carbohydrates, sugar, and fat; and as a result it is no surprise obesity is a rising problem in America. However, obesity is not the only major concern for people who eat such fatty, unhealthy foods. People consume many different types of fats everyday. Some fats promote numerous bodily functions, while others raise levels of cholesterol and increase the risk of cardiovascular diseases (Mayo Clinic Staff 1). Although it has never
you should consider the oils fat content, specifically, fatty acids. Generally speaking, there are typically three classifications of fatty acids and each oil contain all three of them, however, it is classified as the fatty acid that it contains the highest percentage of. The three types of fatty acids are Saturated, polyunsaturated, and monounsaturated; each oil has different nutritional properties and the different types of fatty acids and content levels also effect each one’s cooking ability
are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids. Formula REACTIONS OF LIPIDSLipid peroxidation Lipid peroxidation refers to the oxidative degradation of lipids. It is the process in which free radicals "steal" electrons from the lipids in cell membranes, resulting in cell damage. This process proceeds by a free radical chain reaction mechanism. It most often affects polyunsaturated fatty
cells structures and functions and Vitamin E posses the ability. Vitamin E protect the body from free radicals such as enzyme superoxide dismutase, catalase and glutathione peroxidase. It plays a critical role in the membranes, protecting polyunsaturated fatty acids in cell membranes through its free radicals quenching activity in biomembranes at an early stage of free radical attack. Although vitamin E has low molar concentration in the membranes, but it effectively serves as the major lipid soluble
triglycerides, however, they physically differ at room temperature fats are solid and oils liquid. Their differences in property are what help contribute to its significance in life. A triglyceride consists of fatty acid chains which are attached to a glycerol molecule; fatty acids are chains of carbon atoms, the first carbon atom is attached to an OOH group resulting in a carboxylic group (COOH). The normal length of the chain is roughly 14 to 22 carbons long, with the most common chains
micelle formation is unfavorable relative to a bilayer structure. Fatty acids are another type of lipid. The common feature of fatty acids is that they are all esters of moderate to long chain fatty acids. Two polyunsaturated fatty acids, linoleic and linoleic, are designated "essential" because their absence in the human diet has been associated with health problems, such as scaly skin, stunted growth and increased dehydration. These acids are also precursors to the prostaglandins, a family of physiologically
fats, 3.5percent of polyunsaturated fats and 12.5 percent of saturated fats. These nuts maintain the balance between omega-3-fattyacids and omega-6-fatty acids. These nuts are high in monounsaturated fatty acids and low in cholesterol. Macadamia nuts reduce the risk
SuperTracker analysis, it is ok to consume more linoleic acid than the target amount. “Linoleic acid is a polyunsaturated fatty acid of the omega-6 family” (Sizer & Whitney, 2014). Polyunsaturated fatty acids can help reduce the risk of heart disease or heart attack due to the effect on blood lipids (Sizer & Whitney, 2014). Whole wheat bread, chicken and whole wheat pasta are some of the foods Susanne consumed that are excellent sources of linoleic acid
of a glycerol molecule, with three fatty acid chains attached by ester linkages. Glycerol is an alcohol containing 3 carbon atoms. The fact it is an alcohol means it has an -OH group at one end. Fatty acids are hydrocarbon chains, with a -COOH group at one end. This -COOH group reacts with the -OH group of glycerol, and a condensation reaction occurs, which is what forms the ester linkage. As this breaks apart the -COOH group, which is what makes fatty acids acidic, once the condensation reaction
are made of glycerol and fatty acids. They are present in a wide range of living organisms and help to insulate and protect animals such as seal and marine birds. If there are no C=C double bonds in the hydrocarbon chain, then it is a saturated fatty acid (i.e. saturated with hydrogen). These fatty acids form straight chains, and have a high melting point. If there are C=C double bonds in the hydrocarbon chain, then it is an unsaturated fatty acid. These fatty acids form bent chains, and

Inflammatory bowel disease (IBD) is major disease affecting about 60 thousand people in Australia, about 1.4 million in United States (US) while
placed myself more likely as sedentary, this is because I am a full time student which studies and does school related activities around 45-60 hours per given week. Other things that stood out in this goal spreadsheet were the required essential fatty acids and the moisture goals, two things that I never often underestimate the necessity for. I presume moisture pertains to water content in the food I eat. My Plate analysis Of all the three charts I found this Report easiest to read, and quite informative
The term ‘cognitive health’ is often associated with conditions such as Alzheimer’s disease, ADHD, depression, etc. While an overwhelming body of research and evidence support that cognitive disorders are likely to be influenced by genetic predispositions and environmental factors, there has also been a great deal of research conducted in effort to explore the relationship between nutritional status and cognitive health. It has been found that many aspects of cognitive health are not only impacted
condensation reaction between glycerol and usually 3 fatty acids (the bond is called as ester linkage). The molecule is quite large and has long hydrocarbon tails. If every carbon atom is joined by a single C-C bond then we say it is SATURATED, if there is a double carbon bond C=C then we say this is unsaturated. [IMAGE] A chain with many C=C bonds is polyunsaturated. Most animal fats are saturated fats while most plants are unsaturated. Polyunsaturated fats found in vegetable oils are considered
saturated fatty acids (SFA), replacing them with monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids, and reducing trans-fat (TFA) intake as much as possible (USDA and USDHHS 2010). Generally, animal fats (e.g. lard) are more saturated than plant oils (e.g. soybean oil), and the ratio of PUFAs to SFAs is much lower (Chung and Pomeranz
a cost of $200 million. This product has been approved by the Federal Drug Administration (FDA) with warning labels. What is olestra? The olestra molecule differs from a fat molecule in that it has six to eight fatty acids on a sucrose core, as opposed to three fatty acids on a glycerol core. The bulkier olestra molecule is not digested, absorbed , or metabolized, and thus provides no calories” (Stern & Hermann-Zaidins ,1992 ). It has the same taste and texture of fat, and even retains this
sugars, the key is to be able to distinguish the “good” from the “bad,” as well as to learn ways to select leaner food products more wisely and to moderate our total daily fat intake. The fats that are considered “bad” are the saturated and trans-fatty acids, which are both associated with raising LDL cholesterol (Whitney & Rolfes, 2005, pg 159). An elevated level of LDL cholesterol is linked with artherosclerosis, a plaque formation in arterial walls that causes stiffening and the loss of elasticity
