BIOL 203 Lecture Notes - Lecture 3: Globular Protein, Scleroprotein, Protein Folding
Document Summary
The molecules of life: four classes. Carbohydrates potatoes, pasta: fuel for energy, structural roles, such as clothes. Lipids: fuel for energy, structural roles. Nucleic acids: store transmit and decode hereditary information, small organic molecules make them up, macromolecules large molecules composed of thousands of covalently connected atoms. Molecular structure and function are inseparable, they determine each other. Each cell has different kinds of macromolecules: vary among cells of an organism, as well as in species, and even more between different species. An immense sent of polymers can be made from monomers. Thursday, september 10, 2015: long molecule made up of building blocks, building blocks are monomers, synthesis. Dehydration: water is removed and two monomers bond together. Enzymes can speed this up: breakdown. Hydrolysis: water is added and the polymer is broken down. Proteins: account for more than 50% of dry mass in cells, many different functions. Storage: storage of amino acids (ex: casein in milk for baby animals)
