Document Summary

What is biochemistry? biochemistry is a set of tools or technical skills that lend themselves to many diverse scienti c elds, most of which are related to the study of biomedical research. Primordial universe universe used to be mostly hydrogen and helium after the big bang came carbon, nitrogen, oxygen, phosphorus and sulfur. Human body elements human body is more than 60% hydrogen atoms, followed by carbon and oxygen. Oxygen - building block of biomolecules and water. Hydrogen - component of water, biomolecules and main component of ph in body uids. Carbon - building block of all organic molecules. Nitrogen - component of protein and nucleic acids (biomolecules) Earth"s crust mainly made of silicon and aluminum. Dna and rna both have a ribose sugar (made of 5 carbons) phosphate group attached at 5" giving molecule a negative charge. Other important biological structures membranes are composed of lipids lipid building block = phospholipid (pl)
