Definition of Carbohydrate
The body’s main energy source is carbohydrate; a nutrient found in food which is composed of elements of Carbon (C), Hydrogen (H), and oxygen (O).
There are so many sources of carbohydrate found around us such as:
- Sources of carbohydrate in seeds: rice, corn, wheat
- Carbohydrate Sources in Fruits: Bananas and all kinds of fruit that tastes sweet.
- Carbohydrate Sources for Roots /Bulbs: Sweet Potatoes, Cassava, Taro, Potatoes, and others.
- Sources of carbohydrates in the leaves: Green vegetables.
The function of carbohydrate for the body:
- As the body’s main energy source
- Energy reserves in muscles and liver
- To facilitate digestion
- As a natural sweetener
Division of Carbohydrate
It is a carbohydrate that can not be hydrolyzed into a simpler form divided into trioses, tetrosa, pentose, hexose, heptose. Hexoses in the body include glucose, galactose, fructose, and mannose.
Produce 2-6 monosaccharides through hydrolysis. Oligosaccharides that are important in the body are disaccharides that produce 2 monosaccharides when hydrolyzed, examples of disaccharides include sucrose (granulated sugar), lactose ( milk sugar ), and maltose (wheat sugar).
Hydrolysis of sucrose produces glucose and fructose. Lactose hydrolysis produces galactose and glucose. Maltose hydrolysis produces two glucose molecules. Polysaccharides Produce more than 6 monosaccharides through hydrolysis. Example: starch, glycogen, insulin, cellulose, dextrin.
Definition of Protein
one of the giant biomolecules, in addition to polysaccharides, lipids, and polynucleotides, which are the main constituents of all living things. In humans protein accounts for 20% of the total body weight.
The function of protein in the body
- Regulating the balance of acid-base levels in cells
- function The formation and repair of damaged cells and body tissues.
- Making hormones (hormone synthesis), which helps cells send messages and coordinate body activities
- Making antibodies for our immune system.
- Role in Muscle Contractions – two types of proteins (actin and myosin) involved in muscle contraction and movement.
- Making enzymes. An enzyme facilitates biochemical reactions such as binding to hemoglobin, transporting oxygen through the blood.
- As a backup and source of energy for the body. Three important types of nutrients function as a source of energy for the human body: Protein, Carbohydrates, and Fat
- Meat and Poultry meat
- Fish and eggs
- Dairy products
- Seeds and beans
- Soy products
- mushroom extract.
Distribution Of Protein
Soluble in H2O and salt solutions. Example: Albumin, serum, Lactalbumin ( milk ).
Slightly soluble in H2O, soluble in dilute salts, clump when half saturated with NH4-Sulfate. Example: serum globulin, egg globulin.
Soluble in ethanol 70-80%, insoluble in absolute ethanol and water rich in arginine.
Soluble in saline solutions rich in lysine.
Insoluble in the aforementioned solvents but soluble in acids or bases.
Insoluble in water or salt solutions. Rich with: Glycine, Alanina, Prolin.
Vitamin is a complex compound that is needed by our body that functions to help regulate or process the body’s activities. Without human vitamins, animals and other living things will not be able to carry out living activities and vitamin deficiencies can lead to an increased chance of contracting a disease in our bodies.
- Fat-soluble vitamins = Vitamins A, Vitamins D, Vit E, Vit K
- Water-Soluble Vitamins = Vitamins B and C
1. Vitamin A
Vitamin A is the first fat-soluble vitamin to be found widely. Vitamin A is also known as Retinol.
Function of Vitamin A: Role in Vision, and is one of the constituent components of eye pigment. besides the function of vitamin A also plays an important role in maintaining health, immunity, growth, and development and is very good for maintaining healthy skin.

2. Vitamin B
There are several groups of groups of Vitamin B ( Complex B ) and in general, the benefits of vitamin B play an important role in the body’s metabolism, especially in terms of the release of energy when we do activities.
The role of Vitamin B in the body as a coenzyme compound that can increase the rate of the body’s metabolic reaction to various types of energy sources. Also, several types of B vitamins play a role in the formation of red blood cells. The source of B vitamins comes from milk, wheat, fish, and green vegetables. The types and groups of Vitamin B groups are as follows:
A. Vitamin B1
Another name for Vitamin B1 is Thiamine Hydrochloride -> one type of vitamin that has an important role in maintaining healthy skin and helps the process of burning carbohydrates into energy helps the process of metabolizing proteins and fats and many other functions of Vitamin B1.

The types of foods that contain lots of Vitamin B1 include wheat, rice, meat (liver), milk, eggs, and beans.
B. Vitamin B2
Name another of Vitamin B2 is Riboflavin. The function of vitamin B2 in the body plays an important role in metabolism. Vitamin B2 acts as a component of Coenzyme Flavin Mononucleotides and Flavin Adenine Dinucleotides.
Both of these enzymes play an important role in the regeneration of energy for the body, and oxidation of fatty acids and also play a role in the formation of red blood cells and support the growth of various organs of the body, such as skin, hair, and nails.
Source of Vitamin B2

The effects of vitamin B3 deficiency can cause spasms, muscle cramps, digestive system disorders, vomiting, and nausea.
D. Vitamin B5
Another name for Vitamin B5 is pantothenic acid. The function of vitamin B5 among others that play a role in enzyme reactions in the body and cracking reactions of food nutrients. other than that other functions of this vitamin is as neurotransmitters between the central nervous system and brain and help produce fatty acid compounds and body hormones.
Source of Vitamin B5
Animal foods, ranging from meat, milk, kidneys, and liver to plant foods, such as green vegetables and green beans.
E. Vitamin B6
Another name for Vitamin B6 is Pyridoxine —> is an essential vitamin for body growth, other than that the function of vitamin B6 is energy synthesis and also plays a role in nutrient metabolism and producing antibodies as the body’s defense system (immune).
