Document Summary
Carbs and lipids don"t store info inside of them, where as protein contains it inside of them. Keeps the food eatable for a long time. Speci c molecular structure (shape or conformation) relates to speci c biological function. Structural: keratin (forms hair, nails, feathers) skilk (forms webs) Storage: albumin (in egg white nutrition for embryo) Each amino acid has 3 parts: amino group, carboxylic group, hydrogen, variable group. We have 20 different amino acids in our bodies. Peptide bond: a bond between two amino acids. Protein structure is the sequence in the amino acid. Unique and speci c amino acid sequence encoded in dna. Amino acid sequence speci city in function and folding conformation. H bond forms between -c=0 and -n-h of two peptide bonds.
