chemistry of life

Lipids, Nucleic Acids, indicators

Lipids fats, phospholipids, and steroids - non-polar
hydrophobic do not dissolve in water
fats backup source of energy, insulation and protection
triglycerides glycerol and 3 fatty acids, another name for fats
saturated fats solid at room temperature
unsaturated fats liquid at room temperature
trans fats unhealthy, risk of obesity ad heart disease
phospholipids build cell membranes
steroids cholesterol, estrogen and testosterone(sex hormones)
nucleic acids carry genetic information
nucleotides 3 parts - sugar, phosphate, nitrogenous base
DNA deoxyribonucleic acid produce proteins that form structure and control chemical processes, double helix,chemical that genes and chromosomes are made of
chromosome composed of genes
genes code for particular proteins that code for traits like hair color
RNA small to get out of nucleus and send message to make different proteins,single strand,ribonucleic acid
base pairing A,T,G,C-order of these bases is the code for different genes, A goes with T, G goes with C, Uracil replaces Thymine in RNA
cholesterol comes from what you eat, gives cell membrane flexibility
Indicators Test for specific substances
Litmus Paper determines acid(blue paper turns red) and bases(red turns blue)
pH paper dip into substance and color change is matched against a chart
Benedict Solution test for sugar, turns blue to yellow, green or brick red depending on sugar concentration
Lugol's or Iodine solution test for starch, turns from red to blue-black
