What are fats ?(1)

Fats are one of the three main macronutrients, along with carbohydrates and proteins. Fat molecules consist of primarily carbon and hydrogen atoms and are therefore hydrophobic and are soluble in organic solvents and insoluble in water. Examples include cholesterol, phospholipids, and triglycerides

Why is it important to know the biological molecules?

Biomolecules are an organic molecule that includes carbohydrates, protein, lipids, and nucleic acids. They are important for the survival of living cells. Some of valuable biomolecules have huge demand, which cannot be fulfilled from their renewable resources .

.Give 3 classes of carbohydrates and examples

On the basis of the number of forming units, three major classes of carbohydrates can be defined: monosaccharides, oligosaccharides and polysaccharides. Monosaccharides or simply sugars are formed by only one polyhydroxy aldehydeidic or ketonic unit. The most abundant monosaccharide is D-glucose,

How are proteins made

The information to produce a protein is encoded in the cell's DNA. When a protein is produced, a copy of the DNA is made (called mRNA) and this copy is transported to a ribosome. Ribosomes read the information in the mRNA and use that information to assemble amino acids into a protein. also called dextrose.esources.

.How do you break carbohydrates into monomers

The body breaks down or converts most carbohydrates into the sugar glucose. Glucose is absorbed into the bloodstream, and with the help of a hormone called insulin it travels into the cells of the body where it can be used for energy. ... For people with type 1 diabetes, the pancreas loses the ability to make insulin.

How do we test for fats and proteins ?(2)

Using a dropper add two drops of copper sulphate solution to the test tube. Add 10 drops of caustic soda solution and shake the test tube. Observe the colour of the mixture. Violet colour indicates the presence of proteins in the tested food item.
