BIOL 1501 Study Guide - Endergonic Reaction, Endosymbiont, Headache
Document Summary
Stem cells: gene delivery, marrow stroma, bone, adipose. Tendon and ligament: cardiac muscle, cartilage, biopharmaceuticals. Viruses: a lot of controversy whether or not viruses are considered as living species. Cell composition: a bacterial cell is composed of , 70% water, 30 % chemicals. Molecules in cells: water is the most common compound in cells, cellular chemistry based on the carbon atom, biomolecules are mostly comprised of chemical units called functional groups. Lipids, sugars, amino acids, and nucleic acids are the most common biomolecules in cells. Bonds: weak chemical bonds, e. g. ionic and hydrogen bonds, and very important in biomolecules, they govern the shape of large molecules, and help molecules adhere to each other, water is held together with hydrogen bonds. In cells, the electronegative atoms are usually oxygen or nitrogen atoms. Functional groups: components of organic molecules involved in chemical reactions and interactions. The number and distribution of functional groups give each molecule its specific properties.
