Document Summary
1 million proteins in the human body collectively the proteome. Every human body has small differences in the body"s protein, Genes --> determine amino acid sequence --> protein. Depends on diet that provides adequate diet and essential amino acids. Dna = template to make mrna mrna has the instructions for making protein mrna leaves nucleus. Attaches self to ribosome (protein making machine) trna carries aminoacids to the mrna. Each trna is specific to the 20 amino acids. Enzyme joins them together mrna and ribosome separate. Glutamate replaced by valine - changes shape of hemoglobin, can"t carry oxygen effectively. All cells of body contain genes for making all human proteins but these proteins are only made as needed. Lay down matrix of protein collage & fill with minerals to make bone or teeth teeth. Collagen found in ligaments, tendons, between cells ofartery walls. Skin cells die every 30 days, cells in deeper layers make new proteins to form hair and fingernails.
