Proteins

 What are proteins?

Proteins are long chains of amino acids. There are thousands of different proteins in the body. They. provide all sorts of functions to help us survive.

Functions of proteins

Proteins are providing structure, regulating body processes, transporting materials, balancing fluids, helping with immunity, and providing energy 



Structure of proteins 


Proteins are macromolecules. 

Contain the elements carbon, hydrogen, oxygen, and nitrogen 

The shape, size, and hence function of a protein are determined by its amino acid composition and sequence.

1-Primary Structure

2-Secondary Structure

3-Tertiary Structure

4-Quaternary Structure


Important Points 

They're 20 amino acids that differ in the structure of (R group). Amino acids is made up of 3 parts ( amino group , R group and carboxyl group)

There are many many different proteins because the number of sequence of amino acids. 

Proteins have structure functioning - enzymes are proteins - some hormones are proteins .we need proteins to stay healthy and its needed for growth and repair of body  tissues . 

We should eat 75-100% grams daily of proteins to stay healthy

Carbohydrates

 The Structure of Carbohydrates   Carbohydrates are organic compound of carbon , hydrogen and oxygen. C arbohydrat es have a ring-like structure  Most carbo hydrates are hydrophilic and soluble in water  The general chemical formula of Carbohydrates is (CH2O)n. Carbohydrates are found in living tissues and foods in the form of starch, cellulose, and sugar s. The Functions of Carbohydrates Carbohydrates provide the body with instant, short-term energy. Carbohydrates provide structural support to cells.They are a part of nucleic acids (RNA and DNA). The Importance of Carbohydrates in Our Body Carbohydrates provide the body with instant, short-term energy. Carbohydrates also help with controlling glucose in the blood. Carbohydrates provide structural support to cells.They are a part of nucleic acids (RNA and DNA). Consuming a lot of carbohydrates may lead to “Insulin resistance”,and many scientists believe that insulin resistance leads to a serious condition called ‘metabolic syndrome”

Lipids

 LIPIDS  What Are Lipids? Lipids are organic molecules that consist of a glycerol backbone and 2 fatty acid tails  .  Fatty acids are  long chains of hydrocarbons with a carboxyl group at one end  .  Lipids are   hydrophobic (water-fearing) because of the non-polar bonds between carbon and hydrogen  .  The structure is typically made of  a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic) . (lipids in the  cell membrane) Functions of Lipids Include: - They're used as long-term energy. - Lipids act as a waterproof covering. - They are also thermal  insulators. Why Do We Need to Eat Lipids?  Fats provide needed energy in the form of calories. Fats help our bodies absorb important vitamins. Interesting Facts About Lipids  - They can hold a lot of energy. - They help the body to absorb some of the vitamins - Helping produce hormones. Including estrogen and  testosterone ect.   Types of Lipids  1. Triglycerides 2. Phospholipids 3. Steroids 4.Waxes

Lab reports

Water Lab Experiment: In order to improve our understanding of the elements of a well-balanced diet, we conducted two experiments. In the first, we identified the features of water by observing its interactions with various substances, including itself. We also experimented with how many things water could dissolve and which ones it couldn't. Starch Test: In this experiment, four distinct foods (potatoes, oranges, apples, and pieces of bread) were given iodine drops. A food item contains starch if its color turns greenish-black. Next, we determine which food is starch-free. The apple, potato, and bread pieces had all turned black. The orange, though, didn't change. So, we concluded that oranges are starch-free. Protein Test: The Biuret Solution was used in the second experiment. One method for figuring out whether proteins are present in a sample is by using the Biuret solution. In order to determine whether or not water, milk, soda, or egg whites included proteins, we took fou
