carbohydrates...???
To give us energy

Charbohydrate in daily life
What is Charbohydrate?? Carbohydrates are the most abundant
class of organic compounds found in living organisms.
The carbohydrates are a major source of metabolic energy.
A component of the energy transport compound, ATP.
Carbohydrates also protect your muscles and help regulate the amount of sugar circulating in your blood, so that all the cells get the energy they need.
Carbohydrates participate in cellular functions such as cell growth, adhesion and fertilization.

Carbohydrate originate as products of photosynthesis, an endothermic
reductive condensation of carbon dioxide requiring light energy and the pigment
chlorophyll.
Where is carbohydrate come from???

1. Monosaccharides and disaccharides are soluble in water. they have a sweet taste and a crystalline structure.
2. Polysaccharides, in contrast to mono- and disaccharides, are insoluble in water, do not taste sweet and do not form crystals.
3. Carbohydrates are linked to many proteins and lipids, where they play key roles in mediating interactions between cells and interactions between cells and other elements in the cellular environment

1
Monosaccharides: simple sugar with multiple –OH groups. Base on number of carbon (3,4,5,6).

• Glucose, "blood sugar", the immediate source of energy for cellular respiration.
• Galactose, a sugar in milk (and yogurt).
• Fructose, a sugar found in honey.

The chemical formula for glucose is C6H12O6
It is a six sided ring. Glucose also contains five hydroxyl groups If dissolved in water it’s make closed ring
form (hemiacetal). That is cause reaction between aldehyde/ketone carbonyl group with hydroxyl group.
Glucose rotates polarized light to the right Glucose is the carbohydrate found in the
bloodstream. Blood sugar level in our body around 80 to
120 mg glucose/100 mL (= 0.8 to 1.2 g/L) is considered normal.
Glucose is also formed when stored body carbohydrate (glycogen) is broken down for use.
