At last! without posting for a week, I have finally gone through! HAHA!!!

Now! Since the Lord has granted me a privilege to update my blog (i waited for two hours staring at the computer just to wait for the homepage to appear), I will do it!

Okay! Last, last week... in Biology, our teacher told us some good news! She said that we were going to have a long test every Monday starting that week.

We have many projects, researches to do and assignments to pass in Biology. I like the subject. I, being the beadle, also have to record every human being who has passed their assignments with the air of importance (like someone I know) of a person who stood up on a sea monster because he or she has already passed their assignments on time. And you can't believe the head ache I would get after the stampede is over! It would be matter of time my guts would spread all over the platform!

In English, we were divided into ten groups. Each group is assigned to one chapter of the Animal Farm. Has anyone heard of a fairy story? Fairy story... fairy story or fairy tale? Anyway, that's what the book is. It's a fairy story (what's the difference? Story, tale?)

Okay! Hi Marianne! Hi Athena! Hi everybody! You guys not irritated that I haven't updated for so long? I've been utterly busy (Athena can relate to that).

Here's one of the topics assigned to us that I have researched (real waste of ink! It's even in color!)

Carbohydrates

Lactose is a
disaccharide found in milk. It is pivotally composed of a molecule of β-D-galactose and a molecule of β-D-glucose bonded by a β1-4 glycosidic linkage.

Carbohydrates or saccharides are simple
molecules that are straight-chain aldehydes or ketones with many hydroxyl groups added, usually one on each carbon atom that is not part of the aldehyde or ketone functional group. They are the most abundant biomolecules, and fill numerous roles in living things, such as the storage and transport of energy (starch, glycogen) and structural components (cellulose in plants, chitin in animals). Additionally, carbohydrates and their derivatives play major roles in the functioning of the immune system, fertilization, pathogenesis, blood clotting, and development.
The basic carbohydrate units are called
monosaccharides, such as glucose, galactose, and fructose. The general chemical formula of an unmodified monosaccharide is (C·H2O)n, where n is any number of three or greater. All carbohydrates have a hydrogen to oxygen ratio of 2:1. Monosaccharides can be linked together in almost limitless ways. Two joined monosaccharides are called disaccharides, such as sucrose and lactose. Carbohydrates containing between about three to six monosaccharide units are termed oligosaccharides; anything larger than this is a polysaccharide. Polysaccharides, such as starch, glycogen, or cellulose, can reach many thousands of units in length. Many carbohydrates contain one or more modified monosaccharide units that have had one or more groups replaced or removed. For example, deoxyribose, a component of DNA, is a modified version of ribose; chitin is composed of repeating units of N-acetylglucosamine, a nitrogen-containing form of glucose.
