Term | Definition |
Carbon- | backbone of all organic molecules, 4 bonds (covalent) |
Tetrahedron- | 4 single bonds with other atoms |
Double tetrahedron- | 2 carbon atoms bonded together |
Flat shape- | 2 carbons double bonded |
Hydrocarbon- | molecule with only carbon and hydrogen, stores energy |
4 variations in carbon skeleton- | length, branching, double bonds, rings |
Linear (Length) skeleton- | carbons arranged in a row |
Branching skeleton- | carbons branched off other carbon |
Double bond skeleton- | double bonds between carbon, reduces hydrogen |
Ring skeleton- | carbon arranged in a circle with hydrogen surrounding |
Isomer- | allows carbon molecules to be even more diverse |
3 types of isomers in organic compounds- | enantiomers, geometric isomers, structural isomers |
Enantiomers- | mirror images, L isomer and D isomer, amino acids |
Geometric (cis-trans) isomers- | same atoms, order, and covalent relationships, differ in spatial relationships |
Structural isomers- | molecules with same atoms in different order |
Saturated fat shape- | straight line |
Unsaturated fat shape- | bend |
Trans fat shape- | small kink |
digression- | structure effects function |
Functional group | molecular groups that attach to carbon backbone to make molecules very diverse |
Hydroxyl group: | (-OH), polar, alcohols |
Carbonyl group: | (-- C=O), sugars, ketones and aldehydes |
Ketones- | carbonyl group is bonded to interior carbon of carbon skeleton |
Aldehyde- | carbon group is bonded to terminal on the end of carbon backbone |
Carboxyl group: | (-COOH), carboxylic acids (organic), proton source, lactic, citric, and acetic acid |
Amino group: | (-NH2), acts as a base, accept protons |
Sulfhydryl group: | (-SH), two sulfhydryl groups bond together covalently and form disulfide bond |
Phosphate group: | (-OPO3^2- ), component of phospholipids and important to many chemical reactions |
Methyl group: | (-CH3), not reactive, effects shape of hormones and expression of genes |
