LIFESCI 2 Lecture Notes - Lecture 1: Beta Sheet, Alpha Helix, Alpha And Beta Carbon
Document Summary
Can be formed by hydrogen, oxygen, nitrogen, fluorine, sulfur. N h + o h , h bond formed between h and o. Water lattice, water is fluid so bonds are flowing (therefore shorter bonds) Significant to tertiary structures: x h glycine. Serves as neurotransmitter, fits into corners of proteins: proline. Ch2 x3, connects back to nh2: peptide bonds. Secondary polypeptide chain forms alpha helix, beta pleated sheets. R groups form any type of bonds. All 4 bond types: carbohydrates, 4 categories monosacc, disacc, ogliosac, polysacc, fructose, glucose, galactose, energy currency, glycolytic bonds, ogliosacc det blood type, recognition molecule, starch, glyocgen, cellulose poly) Cellulose = linear lipids: simple lipids (triglyceride) made up of 3 fatty acids + glycerol, connected w/ ester linkages, micelle circle of lipids with head/tails, phospholipid bilayer - two layers. Amphipathic: nucleic acids, 4th carbon oxygen presence determines ribose/deoxyribose, phosphodiester bonds link within strand, hydrogen bonds between 2 strands of dna. Atp --> adp + pi + energy.
