Document Summary
Genes = units of heredity and molecularity. Take info from rna and use to synthesize protein. Nucleotides amino acids 3d protein structure (result of folding linear chains) Structural proteins give cells their shape and ability to move. Regulatory proteins help cells adapt to changing environment. Carry out work of cell, genes code for proteins that synthesize carbohydrates. Control regulation of genes, insure appropriate actions take place. Nutrient storage: seed proteins, albumens, milk proteins. Mobility and contractile proteins: actin-myosins, microtubules, cilia, flagella. *** defined as polymers of amino acids that adopt specific 3d shapes. Collagen: principal structural protein in bone + connective tissues. Insulin: hormone that signals need to store nutrients. ** same 20 amino acids are building blocks for nearly every protein on earth. Amino group, carboxyl group + hydrogen side chain. Everything is covalently bonded to alpha carbon (chiral center) Chemical synthesis of amino acids will give you an equal mix of l and d stereoisomers.
