Document Summary

Hsci 100 lecture 2: levels of matter and the major biomolecules. Our main themes: evolution, variation, competition, selection, adaptation, emergent properties interactions and connections promote novelty. Levels of biological organization: atoms (smallest unit of an element, molecules, macromolecules, organelles, cells (smallest unit of life, tissues and organs (multicellular organisms, populations communities, ecosystems, biome/biosphere. Bonds: chemistry of life, carbon, hydrogen, oxygen, nitrogen, sulphur, phosphorus. Ionic bonds: trade electrons from atoms (na+cl-, hydrogen ions/protons. O --> head: steroids (sex hormones, proteins, amino acids --> structure --, polymerized, hormones, enzymes and transport (diverse, more shapes so adapt, can denature and loose their shape --> loss function, amino acid --> protein. Four levels of protein organization: primary the linear order of amino acids in the polymer. Nucleotides purines: cytosine (c), thymine (t) and uracil (u) are single-ringed pyrimidines. Food molecules need to be breaking down --> produce atp.
