Document Summary
Carbohydrates, proteins, lipids, nucleic acids make up life . Positive control-contains what you are testing for reaction to be predicted. Negative control-does not contain what you are testing for. Made up of monosaccharides (single 5 carbon ring but for 6 carbons) Benedict"s reagent (blue to reddish green) with high heat and high ph. Iodine can interact with these coils and turn bluish-black. We are made up of 20 amino acids, produce 11 on our own. Amino acids can be spoiled by carboxylic acid (-cooh) and amino (nh2) Peptide bonds are formed between 2 amino acids, amino group of one and carboxyl group of the other to form amide bond. C-n bond in peptide reacts with cu2+ of biuret test to produce violet color, needs 4 to 6 bonds for color change. Hydrophobic, slide each other, long hydrocarbon chain, any double bond produce a kink . Lipids are made up of fatty acids bonded to triglyceride.
