functions of proteins
control chemical reactions
Double stranded nucleic acid made from nucleotides sub unites containing A, T, G, and C that stores genetic info in cells
membrane protein with carbohydrates attached that helps cells identify "self" and plays a role in blood types, organ transplants, and germ recognition
macromolecule with a polar glycerol/phosphate "head" and 2 non-polar hydrophobic "tails" used to make cell membranes
Single stranded nucleic acid made from nucleotide subunits containing A, U, C, and G which carries information from the DNA to the cell for protein synthesis
Nucleotide subunit made from ribose sugar, adenine, and 3 phosphates which stores and transports ENERGY in cells

answer: Lipids, including fats, are organic molecules composed of carbon, hydrogen, and oxygen
What are functions of proteins in the human body?
basis for structures, transport substances, regulate processes, speed up chemical reactions, and control growth; building blocks
What are functions of carbohydrates in the human body?
energy source of fuel for fuel for cellular respiration; used to store energy for short periods of time; structural material in plants
What are functions of lipids in the human body?
energy when carbohydrates are scarce; long-term energy storage, cushioning of vital organs, and insulation for the body; also a major component of cell membranes; production of some vitamins and hormones
