Fats or Lipids |What are Lipids |Lipids Definition | Are Lipids Fats? |Source of Lipids | Among the six nutrients lipid or fat produces the largest amounts of energy in our body. Nearly all natural foods contain lipid. Fats or lipids are esters of fatty acids with glycerol. Lipid or Fat Structure |Lipid Molecule | Lipid Molecule Structure | Fat Molecule True fat has one molecule of organic ester of glycerol and three molecules of fatty acids. Classification of Fats or Lipids | Classes of Lipids |Types of Lipids a.Fats or lipids are classified, based on their nature: 1.Solid Fats: Fats that remain solid at room temperature and in normal pressure are termed as solid fats, e.g. animal fat, butter etc. 2.Liquid Fats: Liquid fats remain liquid at room temperature and in normal pressure, e.g. soybean-oil, mustard-oil, etc. b.According to their sources fats are classified into two groups: 1. Plant Lipids: Fats we get fr...

What are Carbohydrates ? One should meet 50 to 60 percent of total calories from carbohydrate foods.  Carbohydrates occupy the major portion of our daily diet. Foods containing carbohydrates are cheaper than other foods. They are the main sources of heat and energy for our body. Formation of Carbohydrates/What are Carbohydrates?/What are Carbs? Carbohydrates are compounds which contain carbon, hydrogen and oxygen as their basic elements. Carbohydrates are called 'Hydrates of Carbon' since they carry hydrogen and oxygen in the ratio of 2:1 respectively just as water does. Thus we can say that any compound containing hydrogen and oxygen in the ratio of 2: 1 can be termed as carbohydrate. Classificationof Carbohydrates Carbohydrates are classified, based on the number of saccharide goups in them: 1. Monosaccharides 2. Disaccharides 3. Polysaccharides 1.Monosaccharides: Carbohydrates formed by a single simple carbohydrate molecule...

Proteins| Nutrients of Food Nutrients of Food When food splits up different types of bio-chemical ingredients are found. These ingredients keep us healthy and active by performing various functions in our body. They are called nutrients. We use these nutrients for our different purposes. Nutrients are of six types. These are- (1) Proteins, (2) Carbohydrates, (3) Fats, (4) Vitamins, (5) Minerals (6) Water So we can say that we can have six types of nutrients from our foods. These nutrients are very necessary for building up our body, guarding it and producing heat. These six nutrients perform more than one fttnction in our body. We shall now discuss about Proteins nutrients here. Proteins The word 'Protein' is derived from the Greek word 'Proteos' meaning 'to take the first place'. Proteins play a significant role in all activities of living organisms. We cannot even imagine a living being without proteins...

Functions of Food and Nutrients To survive in life, food is inevitable. Various nutrients which we get from foods perform different functions in our body. Functions of foods are: 1.They build our body and help us to grow 2.Prevent decays 3.Produce heat and give us energy for work 4.Regulate internal functions of our body 5.Produce preventive to fight against diseases. 1.Build Body and Help to Grow: Protein in food builds up our body. Nutrients are the vital elements of our biological structure. A child grows up from a single cell in a mother's womb. By receiving nutrients from the mother this single cell gradually grows up and divides to form two cells. Innumerable cells are developed by this process and later on a whole of a human child is borne this way. Thus while being in mother's womb a child needs foods for nutrients. Foods help us to grow by building our body. Different nutrients present in food perform the job. 2.Prevent Decays: ...
