why does biochemistry exist
what are lipds, carbohydrayes and proteins and what are their use
what is chromotography
Biochemistry is a combination of biology and chemistry. A study involving those two subjects.
Chemistry involves the study of chemicals and biology involves life. In terms of application and usage of biochemistry: Forensic, Medical purpose, Analysis of Contents, Crime investigation and Research, especially in creating subtances for whatever objective they have in mind.
Lipids (general), also known as fats, are hydrocarbon. Meaning containing only hydrogen and carbon atoms in their structure. Lipids are non-water-soluble, hydrophobic(water-hating) or better, fat-soluble (non-polar) so can pass through the phospholipid bilayer of our cell surface membrane easily. It can sometimes substitute glucose for respiration but producing greater amount of energy since more hydrogen means more reduced NAD and reduced FAD means more ATP per lipid burn in gram. Example of lipid is oil.
Carbohydrates (general), can be in two form: starchy or sugary. Starchy or Starch (example potato) is less sweeter than sugary(example chocolate). Carbohydrate can be classified into three classes: Monosaccharide(glucose), Disaccharide(maltose) and Polysaccharide(Starch). The glucose is always used for respiration in living organism--especially for the brain to function. Cellulose is also a carbohydrate found in the cell walls of plants.
Proteins are what made us. Addition of nitrogen in its structure. Proteins are made from groups of polypeptide which are made from the monomer, amino acids. The basic building block for every organisms. Enzymes, hormones, organs are made of protein. In biology, you may review back protein synthesis. Usually, for growth, regeneration of new cells, immunity included(antibodies are made of protein).
Lipids, Carbohydrates and Proteins are what we call, biological molecules.
Chromatography is a method involving seperation of a compound by their Rf value and time retention.
