Transcript of Anorexia Nervosa
By Saifa Reaz
is an eating disorder that lets people lose more weight than is considered healthy for their age and health
Inadequate food intake
Intense form to gain weight
Self-esteem related to gain weight
Inability to appreciate the severity of the situation
Cells are made of complex molecules called macromolecules. Macromolecules are made of thousands of molecules. The smaller units are called monomers & larger its are called polymer, which are joined form of monomers. There are four types of macromolecules.
Compounds made of Hydrogen, Oxygen & Carbon
Living things use as a source of short term energy
Plants use as structural purpose
Monomer is known as monosaccharide( Simple sugar) & polymer is known as polysaccharide( Starch, Complex sugar)
EXAMPLES: fruits, vegetables, rice, pasta, wood cellulose, glycogen, glucose, lactose, sucrose
lipids are large & varied group of biological molecules that are generally not soluble in water
made of Carbon, Hydrogen & Oxygen
used to store long term energy
makes biological membranes of cells
Monomer is called Fatty acid & Glycerol
Examples: olive oil, canola oil, yogurt, avocado, wax
Macromolecules containing Carbon, Hydrogen, Oxygen, Nitrogen & Phosphorus
Monomer is called Nucleotides.
Nucleotide consists of three parts; 5-Carbon sugar, Phosphate group & Nitrogen base
Capture & transfer chemical energy
Store and transmit heredity
Two kinds of Nucleic Acid; DNA & RNA
Contain Carbon, Hydrogen,Oxygen & Nitrogen
Polymers are called amino acid which is made of monomers, Amino group (-NH2) & Carboxyl group (-COOH)
Peptide bonds link Amino Acids to form Poltpeptides
Control rater of reaction & regulate cell process
Important for cellular formation
Dramatic weight loss
Preoccupation with food, weight, calorie, fat gram & dieting
Refusal to eat certain foods( e. g. carbohydrates)
Frequent comment about feeling fat, overweight
Anxiety about gaining weight or being fat
Slow heart rate
Low blood pressure
Reduction of bone density (osteoporosis)
Muscle loss & weakness
Fainting & fatigue
Dry hair & skin
Long Term Community Prevention
Anorexia involves both mind and body. A team approach to treatment is often best. People involved in anorexia treatment include medical doctors, psychologists, counselors, and dieticians.
Treating anorexia involves three steps:
Getting back to a healthy weight
Starting to eat more food
Changing how one think about oneself and food
One can be a role model for healthy eating, exercising, and body image by not making negative comments about their own body or anyone else's
One can seek advice from a health professional
One can avoid threats, scare tactics, angry outbursts, and put-downs.
Anorexia is often a symptom of extreme emotional distress & self hate, by managing emotional pain ans stresses it can be prevented
Low Carb Diets
Many people have adopted a low carbohydrate way of eating. With the alarming increase in obesity, people are interested in quick, effortless solutions to weight loss.
A low carbohydrate diet restricts foods that have carbohydrate in them such as grain products, fruits and vegetables, legumes, milk, yogurt, and foods with added sugar.
Low carbohydrate diets are high in protein and fat. Eating high fat, high protein foods cause us to feel full sooner. Also, it have many foods that are not allowed which results in a decrease of calorie intake. This contributes to weight loss. But it does not stay forever. After one loses weight and goes back to normal diet, they are the same as before
Body uses carbohydrates as the main fuel source. It breaks sugars and starches into simple sugars during digestion and absorbed into bloodstream as glucose. This glucose is used for energy that we use to walk, talk even think. Extra glucose is stored in liver, muscles and other cells for later use. Proponents of the low-carb diet believe that decreasing carbs results in lower insulin levels, which causes the body to burn stored fat for energy.
Following a low carb diet results in high blood pressure, bone mineral loss, gout, kidney stones and constipation.
People who suddenly and drastically cut carbs, may experience a variety of temporary health effects, including:
In addition, some diets restrict carb intake so much that they result in nutritional deficiencies or insufficient fiber. This causes health problems as constipation, diarrhea and nausea. Eating carbs that are high fiber, whole grain and nutrient dense can improve the health profile of some low-carb diet programs.
Dehydration Synthesis & Hydrolysis Reaction
Dehydration Synthesis is the reaction that links small parts by taking out water.
monomer+ monomer polymer + water
Hydrolysis Reaction is a reaction that splits up big parts by adding water
polymer + water monomer+ monomer
Catabolism is the set of metabolic pathways that breaks down molecules into smaller units to release energy.
In other way catabolism breaks the large molecule and creates more than two.
Anabolism is the set of metabolic pathways that construct molecules from smaller units.
In other way, its the reaction that joins or combines the molecules
Function of Different Types of Carbohydrates
Maintaining hormone balance in the body.
Stimulating the functioning of the immune system.
Helping in regulation of sugar levels.
Preventing the breakdown of amino and fatty acids.
Function of Unsaturated and Saturated Fatty Acid
Saturated fatty acid
provide with concentrated form of energy
essentials to carry fat soluble vitamins
protect essential organs
Unsaturated fatty acid
High in HDL
source of good cholesterol
Unsaturated Fat is considered the good one as it consists of double bonds and hard to build, so it doesn't block arteries.
Weight Gain & Loss in Term of Macromolecules, energy, & Calories
Cells are made of complex molecules called macromolecules. Macromolecules are made of thousands of molecules. Four main macromolecules are, Carbohydrate, Lipid, Protein & nucleic acid. These macromolecules are included in e food that we consume each day. From these, we get our essentials that help us to survive.
