Document Summary
Most of our energy - but not enough materials for everything else. Polysaccharides (glycogen - animals) (cellulose - plants, broken down by symbiotic orgs in animals) More commonly stored as fat, since glucoses attract water > heavy. Oh bonds contain energy (broken down glucose releases co2 and h2o) 1 glycerol, 1 phosphate, 2 fatty acids. Triglycerides: major energy storage molecules (fats, oils) Kinked fatty acid = double bond = unsaturated fatty acid (less packing) We do(cid:374)(cid:859)t ha(cid:448)e e(cid:374)z(cid:455)(cid:373)es h(cid:455)droge(cid:374)ated fats (unsaturated) Steroids i. e. cholesterol - sex hormone substrates. Cell work like form enzymes, structural components, signaling molecules, channels. Not stored longterm, broken down for energy or become fat. Amino acids: amine group (?) and carboxyl group. Humans are eukaryotes = true membrane enclosed nucleus. Rbc are anuclear, so it can fit into capillaries. Fertilized human egg (zygote) is diploid, v large due to needing much nutrients for ~week. 120tr cells and 200+ types in human.
